#9: Invaders in Your Yard: The Hidden Dangers of Invasive Species

There’s an invasion happening right under our noses—one that’s likely reached your own backyard. You may have even unknowingly played a part in it.

This is the spread of invasive plants, animals, and fungi. Once removed from their native habitats, these species reproduce rapidly, disrupting ecosystems, threatening biodiversity, and even endangering our food, health, and recreation.

Invasive species are wreaking havoc in every corner of the world, often with our unwitting help. But with knowledge, care, and action, we can turn the tide.

Griff Griffith guides you on a journey explaining how invasive species pose a threat, how they got here, and what you can do. Griff is joined by Dr. Sara Kuebbing (from the Yale School of the Environment), Emelie Swackhamer (Penn State University Extension), and Carl Klarner (Redwood Invasive Plant Eradicators).

[00:00:00] Michael Hawk: Hey, Michael here. As I was putting this episode together, I couldn’t help but think of a time about 12 years ago. I had no idea that the beautiful photo that I shared with my friends actually captured a devastating scene.

[00:00:12] Now, it showed a field of dense yellow flowers with vibrant green leaves. mirrored by the equally lush green hills in the distance, some of which were actually dusted with snow. I was new to California at the time, and I thought maybe this was one of those famed super blooms.

[00:00:27] But it turns out those mustard flowers were newcomers too, at least on an ecological time scale. But these newcomers were harming the environment in ways that the untrained eye could not see.

[00:00:39] Emelie Swackhamer: , humans move things around a lot and we’re good at moving things that we don’t intend to move because we’re so mobile.

[00:00:45] Griff Griffith: That’s Emelie Swackhammer, a recently retired extension educator for Penn State University And she’s not talking about how deciding to move your reclining chair leads to the unintended consequence of reorganizing your entire house.

[00:00:58] She’s actually referring to moving living things. Maybe you went for a hike and later realized that a bunch of prickly seeds hitched a ride on your pants and shoes. Or you purchased seeds online and got something entirely unexpected. Or you moved across country and took some garden plants with you, not realizing insect eggs, fungal spores, and soil organisms hitched a ride with you. Luckily, many of these examples turn out harmless, but sometimes it can be disastrous.

[00:01:26] Carl Klarner: a word I’m going to use a lot in this conversation is liana. A liana is, is a vine after it becomes woody, you call it a liana. A lot of people refer to it as the trunks of the ivy or whatever. I mean they get huge and I have like a trophy haul of these Lianas and I take them to events and show them to people.

[00:01:45] People just can’t believe that it’s Ivy. They’re like, that’s Ivy? Ivy grows in lots of different weird ways. For example, deadfalls. So, Ivy will get up in a tree and especially if it’s a deciduous tree, it’ll kill the tree. The tree will fall right down and a lot of the time the ivy doesn’t die and it sends out octopus arms all over the place and they in turn root and it becomes this giant monstrosity of a plant that’s just spread out over like a hundred feet or more it creates its own canopy and it’s, a lot of times it’ll send stuff out and go up other trees that are nearby.

[00:02:22] Griff Griffith: Carl Klarner is talking about English Ivy. You know, that docile, sophisticated looking plant that crawls up the walls of Ivy League school buildings and many other college campuses across the nation. European colonists brought this plant to the United States in the 1800s, maybe even earlier , looking to replicate the familiarity of their homeland.

[00:02:41] my own Welsh and Irish ancestors brought this plant to create wreaths during the winter that they believed would ward off evil spirits.

[00:02:48] But ivy escapes the confines of campuses and estates, and now it spreads wildly throughout many parts of the USA, creating the havoc that Carl describes.

[00:02:56] In fact, hundreds of plants, animals, insects, bacteria, fungi, and even viruses get spread around the country and around the world, and when they reach their destination, they can take on new and unexpected properties, spreading out of control, and wreak havoc on the areas they colonize, just like those mustard flowers Michael described a moment ago.

[00:03:17] Maybe you heard of some of these. Let’s have an invasive species roll call.

[00:03:20] Kat Hill, Laura Schare, Preston Ernest: Zebra mussel, kudzu, emerald ash borer, tumbleweed, pampas grass, Asian carp, house sparrow, wild pig, Bradford pear, spotted lanternfly, European starling, tree of heaven, Japanese beetle, Argentine ant, salt cedar, eucalyptus, glassy winged sharpshooter, European core borer. Quagga, Asian citrus psyllid, Norway rat.

[00:03:57] Griff Griffith: Wow, I know I recognize many of those. And I know they can impact everything from food production to water supplies to native plant diversity. Even wine and baseball bats are at risk. It sounds like an invasion. And in a way, it is. It is, but as overwhelming as it may sound, it is not too late. And as you’ll hear, you too can help.

[00:04:19] Griff Griffith: I’m Griff Griffith, and welcome to Jumpstart Nature.

[00:04:31] Dr. Sara Kuebbing: How do you define an invasive species? You could do an entire podcast or series of podcasts just on this. But my preferred definition is a species that’s been introduced by humans. So

[00:04:50] it’s not a species that migrates on its own or, you know, for whatever reason. Floats somewhere just sort of by happenstance, but moved by humans and generally moved by humans across either big distances, so it makes it less likely that that species would move it on its own, or over just barriers that would be hard.

[00:05:10] A mountain range, an ocean, something that is hard for that species to cross on its own. So a human, assisted migration of a species that once it arrives in its new location, it can spread very widely on its own. So that initial movement with humans and then spreading far beyond.

[00:05:31] One thing you may hear from a lot of especially policy focused organizations add on to that definition, is that there has to be an example of a harm, an ecological harm, a human health harm, an economic harm that that species poses

[00:05:47] Griff Griffith: Dr. Sarah Kuebbing is the Director of Research, the Yale Applied Science Synthesis Program.

[00:05:53] Dr. Sara Kuebbing: I have always been interested in understanding how we manage ecosystems and how we can manage ecosystems for multiple benefits. One of those benefits that I really love is biodiversity. Protecting nature for nature, but obviously humans use ecosystems for the services and the things, the commodities that they provide as well

[00:06:13] and so figuring out how do we most responsibly use these ecosystems in a way that doesn’t just take for humans, but also prioritizes and values other life forms that are using them. So that’s like the big broad arc.

[00:06:26] And that’s really what brought me into being really interested in invasive species.

[00:06:30] Griff Griffith: As Dr. Kibbing said, an invasive species is brought to a new location by people, sometimes purposely, as with many garden plants, and sometimes accidentally.

[00:06:40] And these plants, animals, or fungi, escape control and cause harm to our ecosystems, crops, health, or property.

[00:06:48] So no, termites and aphids usually aren’t invasive species because they are native and they’ve developed long term complexly important roles in their environment .

[00:06:59] Yes, they might be a bit of a pest at times. Say if those termites have turned their sights on the wood frame of your home, but in nature or even just a few feet away from your house, they are decomposing dead wood, creating soil and cycling nutrients back into the ground.

[00:07:15] Carl Karner, who you heard from earlier, has taken a special interest in English Ivy and the negative effects it’s had near his home in the majestic redwoods of Northern California. He was seeing ivy destroying habitats, not only in parks and public lands, but also on private properties.

[00:07:31] Carl Klarner: listeners are probably pretty aware of, that book, Nature’s Best Hope. If nature is only in these protected areas and parks, that’s it. We’re done,

[00:07:41] Griff Griffith: That’s Nature’s Best Hope by Dr. Doug Tallamy, who we featured in our very first Jumpstart Nature episode, The Yard of the Future.

[00:07:49] By the way, Carl is not an ecologist by training. He’s a political science professor and took special interest in invasive species.

[00:07:57] Inspired to do something, Carl founded RIPE.

[00:07:59] Redwood Invasive Plant Eradicators. More on that later. Let’s hear from Carl about the impacts of ivy.

[00:08:06] Carl Klarner: English Ivy, it gets on the ground and it chokes out native plants. Invasive plants are the second biggest driver of biodiversity loss , the first is obviously habitat change, but, it’s pretty expensive to buy land and set it aside for nature, but it’s a lot cheaper to just whack invasive plants.

[00:08:23] It’s also a great way to, promote native plants.

[00:08:28] English ivy all these native plants on the ground that are super important for the ecosystem.

[00:08:34] You know, like, all the things that insects eat and, the food chain all the way up from them is being affected by the ground ivy. , And, I’ve seen very large pieces of forest that are just nothing but ivy. The ivy is coming up literally to your knees. It’s just everywhere, and it’s growing over elderberry tree, you know, it’s like draped over everything, it’s all up the trees.

[00:08:59] And a lot of times it kills those trees, or it at least hurts the trees, makes them less healthy. It’s not just because it steals the water from the trees, but it also blocks sunlight, can act as a sail, tree can blow down.

[00:09:14] It does so many other harms too, like, it does destroy structures. Right next door to me, actually, is a giant workshop that was, it’s made out of brick and concrete.

[00:09:24] The whole roof is caved in because it’s got literally thousands of pounds of ivy on it.

[00:09:30] Griff Griffith: There are plenty of invasive plant species from tree of heaven to tumbleweed to Bradford pear, which by the way, doesn’t even produce pears. And much of the grass growing in the Western United States. And it causes more frequent and higher intensity wildfires, threatening many other native plants and animals, such as the sage grouse.

[00:09:50] As a quick aside, I want to be clear that invasive plants are very different from what we call weeds. Weeds are simply plants growing where we don’t want them.

[00:10:00] You may not want a native goldenrod growing in the cracks of your driveway. So you might consider that otherwise very beneficial plant to be a weed in that case. Invasive species reach a much more destructive level.

[00:10:11] In the case of tumbleweeds and English ivy for example, it’s easy to see how they are considered invaders, with their roots and leaves spreading across an entire landscape, but sometimes the infiltrators are much smaller and easily overlooked until it is too late.

[00:10:30] Emelie Swackhamer: They’re often feeding on the trunks of trees because their mouth parts at that point are pretty strong and they can pierce right through the bark of the trunks. And you’ll find them in big groups. While they’re feeding they’re withdrawing sap out of the tree and that’s you know their energy is coming from the energy of the tree, but they are inefficient in how they digest that and they pass a lot of it through their bodies and they excrete partially digested tree sap and we call that honeydew.

[00:11:02] And this honeydew, allows the sooty mold to grow. Sooty mold is a collection of different fungi, and it looks just like this black mold, and that can be on anything that’s underneath these insects.

[00:11:17] Griff Griffith: Emelie Swackhammer is describing an invasive insect that has been getting a lot of attention in recent years. The Spotted Lanternfly. Despite its name, it’s not a fly at all. It’s a type of insect called a plant hopper, which is why it has special mouth parts that allow it to pierce tree trunks to get at the nutrient rich sap underneath.

[00:11:36] Emelie Swackhamer: And they’re really quite pretty even in the nymphal stage. In the spring the eggs will start to hatch. When they hatch, the nymphs that come out of the eggs are really tiny.

[00:11:46] They’re black with white spots, and then they go through four nymphal stages. So going to that fourth stage, they’re, black and white but they also have red coloration on them.

[00:11:57] Their favorite host is the tree of heaven. it’s Latin name is a Ailanthus altissima and that tree has a thinner bark and a smooth bark. So they can certainly pierce through that and, and that’s a, uh, we call it a sentinel tree.

[00:12:12] It’s a tree to be watching. If you haven’t found them in your area yet, that’s where you might see them first.

[00:12:18] Griff Griffith: Tree of heaven. Some people in parts of the United States would call it the tree from hell. It’s an invasive species and can spread and out compete native plants easily. So maybe you’re thinking, Hey, the spotted lanternfly might actually help here by, you know, eating the tree of heaven.

[00:12:34] Well, unfortunately the lanternflies are not super picky. They’re like a teenager who loves potato chips, or in this case, the tree of heaven, but will gladly eat many other snacks laying around.

[00:12:45] Emelie Swackhamer: I have seen them feed on all kinds of other trees. So what comes to mind are the black walnut trees. The adults can feed on black walnut tree trunks and they will pierce through like the valley of the bark.

[00:12:57] Griff Griffith: Dr. Kibbing adds

[00:12:59] Dr. Sara Kuebbing: they’re of huge concern actually to the agricultural industry because, grape growers and, and apple orchard and plum orchard growers are really concerned about the damage that they could potentially do to their crop species.

[00:13:10] Griff Griffith: the spotted lanternfly invasion is still in its early stages, it’s unclear how it will evolve. Certainly, the lanternfly will continue to spread. It’s currently found in roughly 17 states in the Northeast and Midwest, and as it encounters new plant species, we may discover additional negative effects.

[00:13:29] As you might imagine, states like California and Florida, with their huge citrus, grape, and wine industries, are watching closely.

[00:13:36] In previous episodes, we’ve talked about the importance of native plants. As a quick recap, remember that plants are the source of nearly all of the energy the animals get. And unfortunately, you and I can’t photosynthesize, so we either eat plants, or we eat other things that eat plants on our behalf.

[00:14:04] Of course those plants don’t want to be eaten, so they defend themselves with toxic and bad tasting chemicals or even with physical defenses like thicker bark or super sticky sap. In turn, insects develop clever workarounds like higher tolerance for those chemicals or stronger mouths to penetrate the bark.

[00:14:23] This is sometimes called the evolutionary arms race. The plants and animals keep one upping each other, but also keep each other in check, each only gaining temporary advantages and both in the long run endure.

[00:14:37] Think about how monarch butterflies are able to eat milkweeds while most other insects and mammals can’t. These types of specialized relationships exist all over the insect and plant world.

[00:14:48] Every so often, an insect is accidentally introduced from another region or continent, and it turns out that they already have a taste for our local plants too. But our plants haven’t needed to develop defenses for these intruders. After all, they’ve never seen them before.

[00:15:03] A great example of this is the Emerald Ash Borer.

[00:15:07] It’s a metallic green jewel beetle from Northeast Asia that has co evolved to use ash trees as their host trees. In other words, the emerald ash borer eats those Asian ash trees, but since they evolved together, neither the Asian ash trees nor the emerald ash borer have a particular advantage. They keep each other in check.

[00:15:27] Jumping over to North America, it turns out we have different kinds of ash trees, but they are closely related to those in Asia. And it just so happens that the emerald ash borer is able to eat American ash trees just fine.

[00:15:41] And as beautiful as those beetles are, their appetites can have devastating consequences.

[00:15:46] How so? For that, we’ll need a quick biology detour. It’s fascinating stuff, though, I promise.

[00:15:52] burrow beneath the bark to feed on the nutritious and sugary layers of the tree, called the phloem and cambium.

[00:16:00] The phloem is where sugars and nutrients are transported in the tree, and the cambium is an important source of cell growth. If these layers sound important for the tree, it’s because they are.

[00:16:10] The ash borers meander under the bark, creating tunnels. And if enough borers are feeding on a tree, they can totally encircle the trunk of the tree, cutting off the flow of nutrients to the points higher in the tree. This is called girdling, and once this occurs, the tree will be dead in a few years.

[00:16:27] American ash trees don’t have defenses against this exotic insect. So these beetles are able to grow and reproduce very quickly.

[00:16:35] As a result, an estimated 100 million ash trees have been lost to this invasive species. Areas with infestations have lost as many as 99 percent of their ash trees.

[00:16:47] So this means that all of the native insects that rely on ash trees, like how the monarch relies on milkweed, are going to struggle, if not disappear entirely, decreasing biodiversity and weakening the food web.

[00:17:00] The problem with talking about biodiversity is that it’s hard to see, unless you’re like me, someone who closely observes nature.

[00:17:08] Ash wood is popular in furniture and cabinetry because of its strength, flexibility, and attractiveness. And the loss of these ash trees has dramatically impacted the supply of of these ash products.

[00:17:19] If you’re a baseball fan, you might know that the wooden bats used in Major League Baseball have traditionally been made of white ash. It was the wood of choice because it was lightweight and had a good ability to absorb shock while still being durable.

[00:17:43] A few players use maple bats, which is a harder wood but heavier, and the shift away from ash has been accelerated because of the emerald ash borer. But how did these invasive species get here and moved around?

[00:17:54] Dr. Sara Kuebbing: generally we can lump all of these introduced species that we bring in and just sort of two broad categories. There’s the species we intentionally bring in because we like them. They tend to be plants and animals.

[00:18:07] Pets, plants, animals.

[00:18:09] Griff Griffith: Like English Ivy, House Sparrows or the Burmese python, which is causing problems in the Florida Everglades.

[00:18:15] Dr. Sara Kuebbing: And then there’s the things that accidentally come in, usually as like hitchhikers on boats or on wooden pallets or other things hitchhiking as we move around planes. And so on the intentional side, of these things that we want to transport. We transport live plants all the time.

[00:18:32] Griff Griffith: Organisms find countless ways to hitch a ride, nestled in the soil of the potted plants we transport, hidden among shipments of fruits and vegetables. Clinging to firewood we take to a campground or stowed away in the ballast water of boats.

[00:18:47] Take zebra and quagga mussels. reproduce at astonishing rates, altering lake chemistry. Their shells clogging waterways and vital water infrastructure. They cover beaches in dense layers once inviting shorelines nearly impassable.

[00:19:05] Seeds and pathogens can even attach to our shoes and clothing. In fact, it’s believed that the fungus that has decimated bats in North America by causing white nose syndrome was first brought to North America by people who visited European caves, bringing the fungus back on their gear.

[00:19:20] Each of these examples we’ve talked about today have had a big impact. For example, I mentioned that we’ve lost a hundred million ash trees in our Eastern deciduous forests.

[00:19:30] Now consider that chestnut blight, an invasive pathogen, wiped out nearly 4 billion chestnut trees. The American chestnut was once the most abundant tree in the forest of the eastern United States and now is virtually extinct.

[00:19:43] And we’ve lost 80 percent of American elm trees due to an invasive fungal infection. And other invasive species are affecting beech trees, hemlock trees, oak trees, and more.

[00:19:54] Today’s Eastern Forests are a far cry from what they were just a few decades ago, AND we can tell similar stories of our lakes, rivers, deserts, grasslands, you get it.

[00:20:06] Wow. If you think too hard about this, it might lead to a case of ecodepression. But I wouldn’t tell you about all this unless there was some hope in something you could do to help.

[00:20:15] Dr. Sara Kuebbing: It becomes very easy to be sort of nihilistic and be like, oh, there’s nothing we can do about it. And that’s just not true. And, and sometimes we can do, we can have our highest impact locally. And so even if the problem is very large and we don’t have control.

[00:20:29] You can still remove an invasive plant from a forest within your town.

[00:20:34] right? I used to work up in Vermont, doing a lot of invasive plant both management and sustainability stewardship of lands, but also outreach and education. And there was an aquatic plant, called water chestnut.

[00:20:44] And there was a lot of outreach efforts in sort of the Lower Lake Champlain watersheds and Lower Lake Champlain to educate people on what it looked like. And the plant sort of just floated on top of the water and you could very easily pull it out , of the water and usually remove it. And they found, , a boy scout who had done a little unit on invasive species, found a water chestnut and a bigger water body where it quickly would’ve spread and caused a lot of, you know, economic impact of recreation and prevention of recreation and he prevented this whole invasion because he saw it and he had learned about it and he put in his canoe and he, you know, told someone at the dock that he had found it and people went out and found a couple others and that was a prevention of an invasion all through this like very local outreach and education.

[00:21:32] Griff Griffith: And this is exactly what Carl Klarner is doing with his group called RIPE.

[00:21:36] Carl Klarner: Redwood invasive plant eradicators. We’re trying to fill some unmet, needs when it comes to, plant eradication. One is, existing organizations and, and the, the. people that are focusing on invasive plant eradication are almost exclusively focusing on parks, protected areas, so we go to private properties, lot of that time is like our most effective work.

[00:22:01] Griff Griffith: Carl told us that the most return on his investment is targeting fruiting ivy.

[00:22:06] That’s because many birds and some mammals will eat the fruit and then we’ll poop it out somewhere. Depositing seeds in a new location.

[00:22:13] Carl Klarner: and that’s how it propagates.

[00:22:14] I’ve almost never seen it fruit, unless it gets up into a tree or some other place that’s high like a fence or stump or something and then it takes it actually quite a while to produce the berries, even when it’s in that tree like something like seven years or ten years or something like that, once it starts producing those berries it it goes into a hyperdrive.

[00:22:36] It’s super easy to kill if it’s in the trees. You just girdle the ivy around the base, everything above it dies. So, back to how many pounds of ivy are in a tree. Like a big infestation can have 2, 000 pounds, and in like 20 minutes I can kill 2, 000 pounds of ivy.

[00:22:50] If I’m pulling it out from the ground Which is important, it is important to do that, but you’re only going to get like, I don’t know, 50 pounds an hour.

[00:22:59] Griff Griffith: If you have ivy on your property, you might want to remove it and definitely do not let it climb and fruit.

[00:23:07] In fact, if you have any invasive plant, remove it as soon as you can. And there are several common backyard plants, such as tree of heaven, Japanese honeysuckle, Chinese honeysuckle, bamboo, wisteria, pampa grass, jubata grass, heavenly bamboo, kudzu, scotch, broom, and purple loose strife

[00:23:24] just to name a few.

[00:23:25] But there are so many more.

[00:23:28] I wish there was a simple resource that cataloged invasive species, but there aren’t any comprehensive and user friendly sources, but a great place to start is the USDA’s database at www. invasivespeciesinfo. gov. It takes some digging, but you can get lists for the most common terrestrial and aquatic invasives. And they have state by state maps under the resources section of the website.

[00:23:54] We’ll link to those in our show notes.

[00:23:56] And you know that amazing app, iNaturalist, that we often talk about. You can use it to help identify plants and insects.

[00:24:02] They label species that are generally agreed to be invasive, so maybe go on a backyard safari with iNaturalist to discover the invasive species on your property.

[00:24:11] Dr. Sara Kuebbing: Almost every state has university extension service

[00:24:15] researchers at the State University that almost certainly will deal with the local invasive species that are causing problems in agricultural or rangeland or forested systems.

[00:24:26] Griff Griffith: Dr. Kuebbing brings up a great point. You can contact your local extension office and just ask them about local resources or specific plants or insects in your yard.

[00:24:37] In fact, Emily Swackhammer who you’ve heard from throughout today’s episode is a recently retired extension agent. And speaking of extension offices, if you spot a spotted lanternfly, immediately contact your extension office. If you are confident in your ability to identify them, most places in the United States recommend that you kill them on sight. Here’s Emelie.

[00:24:57] Emelie Swackhamer: It’s important to identify them first. So we don’t want people to be freaked out by every insect, indiscriminately killing everything. It’s important to know that some insects are beneficial. There’s a lot of native insects.

[00:25:11] But if you’re positive that it’s a Spotted Lanternfly, it shouldn’t be here. We do want people to kill them. So there’s a variety of ways to do that. Simply getting rid of Tree of Heaven, which is their preferred host tree, it’s also from Asia, can help reduce populations in that particular location.

[00:25:30] Mechanically, , small scale, fly swatters. People have used vacuums like shop vacs to suck them off the trunks of trees. We have, developed traps – modified circle traps are great and you can catch hundreds of them and protect a particular tree with a trap.

[00:25:48] And then if you really need to, you think you need to use pesticide spray, don’t use home remedies. Dish soap is not an insecticide that’s labeled for use. It can burn your plants. Dish soaps have degreasers, fragrances, colors, often antimicrobial products; these are all things that you don’t want to use as insecticides. but you can get some really, , soft, environmentally friendly insecticides, even some of the botanical oil insecticides work pretty well against spotted lanternfly. Certainly things like insecticidal soap and horticultural spray oil And then there’s neem products. There’s pyrethrum, which is an extract of chrysanthemums.

[00:26:32] Griff Griffith: We have a link to how to build one of those traps Emily mentioned in our show notes. But how can we prevent hitchhiking species from getting into new territories in the first place?

[00:26:43] One way is monitoring and inspection. Virtually every boat owner already knows that they need to have their boat inspected for invasive mussels before putting it in a new body of water.

[00:26:54] but also:

[00:26:54] Emelie Swackhamer: there’s a lot of things coming in our ports all the time. And the people that work at the ports to inspect the goods that are coming in are amazing. They’re so well trained and, you know, they’re looking all the time.

[00:27:09] But you can imagine. how difficult that is if you have a barge full of products and you’re the inspector of the day.

[00:27:18] Dr. Sara Kuebbing: I just wish we would put more emphasis on monitoring systems.

[00:27:22] to both detect things early on entry or even again like prevent those hitchhikers and that’s more resources.

[00:27:29] I just like to think of all the amazing things that humans have done right like we’ve sent people to space. Humans can actually achieve really significant things and all these things we can do and we have actually a lot of the information and knowledge we need to do it. We just have to decide that we want to invest the time and the resources.

[00:27:47] in preventing it.

[00:27:48] Griff Griffith: And much of that can start with you, whether you’re thinking of taking your garden plant with you when you move to a new state or considering transporting fruits and vegetables through checkpoints.

[00:27:58] Stop and think about the possible consequences. Always buy firewood locally at the campground so you don’t mistakenly transport an invasive beetle and make sure plants and seeds you buy are not invasive and from reputable sources.

[00:28:12] Help educate your friends, family, and neighbors. Maybe even suggest this podcast to them.

[00:28:18] Your local county, state, national parks often need volunteers to help remove invasive species. Get out there and lend a hand.

[00:28:24] We just scratched the surface today, but without more education and without more people who care, the things we love in nature are at risk.

[00:28:33] What did you think of today’s episode and what invasive species are you concerned about in your area? We’d love to hear from you. Seriously.

[00:29:23] Griff Griffith: do you want me to do a bunch of varied voices or are you going to have a bunch of different people?

[00:29:26] Huh, that’s a good question. Um, this probably isn’t what you had in mind but I’m having fun so I’m gonna go with it, zebra mussel, kudzu. Emerald Ash Borer. Tumbleweed. Pampas Grass. Actually, it probably should be Jabata Grass. Asian Carp. House Sparrow. Bradford Pear. Spotted Lanternfly. European Starling. Tree of Heaven. Japanese Beetle, Argentine Ant, Salt Cedar, Eucalyptus, Glassy Winged Sharpshooter, European Corn Borer, Quagga, norway rat.

[00:00:00] Griff Griffith: On a crisp morning in 1983, Steve Jobs was on a mission.

[00:00:09] A helicopter carried him high above the rolling green hills just south of Silicon Valley as he searched for something that would change the future of Apple computers.

[00:00:20] With him was an Apple Vice President and a real estate consultant. Their objective? Find a new headquarters for the rapidly growing computer company.

[00:00:29] Jobs had found his site, the lush grasslands and oak savanna covered hillsides of Coyote Valley.

[00:00:36] Griff Griffith: Soon after, Apple owned the land and it looked like the headquarters project was off and running.

[00:00:42] Andrea Mackenzie: the Coyote Valley landscape has captured my heart.

[00:00:46] It’s

[00:00:46] a, in many ways, a forgotten landscape, a tortured landscape, and yet it survives and keeps coming back time and time again. It’s showing that resilience for nature and resilience for people.

[00:01:00] And turns out that the Coyote Valley is one of the most important undeveloped valley floor landscapes in the entire San Francisco Bay region. And so each day we’re discovering more and more about why this kind of a place adjoining the 12th largest city in the nation is so very important.

[00:01:20] Griff Griffith: , Andrea McKenzie is a general manager of the Santa Clara Valley Open Space Authority, an organization that stewards much of the land in Coyote Valley.

[00:01:29] Now you might be wondering how she can refer to the space as undeveloped when a tech giant like Apple , with a driven and unstoppable leader like Steve Jobs was intent on developing it.

[00:01:40] This is an amazing story of an incredible land with equally incredible history.

[00:01:47] Chairman Lopez: And if you look west , you would see the peaks of the Santa Cruz Mountains, and one of the tallest peaks. That’s Mount Umunum, and that’s the location of our creation story .

[00:01:56] Griff Griffith: And the story of what happened to Coyote Valley is full of unexpected alliances.

[00:02:01] Megan Fluke: I jokingly suggested that he should start donating to, uh, support all of the work that they were creating for me and the team. well, wouldn’t you believe it? they’ve been an annual donor ever since

[00:02:13] Griff Griffith: A little luck.

[00:02:14] Stu Weiss: one of the things I noticed is that every time a coyote valley development started getting some momentum the economy would crash or there’d be a tech crash, and the plans would go away for a few years.

[00:02:27] Griff Griffith: And Incredible Perseverance.

[00:02:29] Megan Fluke: yeah, it was hard. But at the end of the day, we were working in community

[00:02:34] Coyote

[00:02:34] Griff Griffith: Valley’s Story is one of hope and inspiration and it’s a model for nature conservation of all kinds.

Theme Music Here

[00:02:40] Griff Griffith: I’m Griff Griffith, and welcome to Jumpstart Nature Okay. You’re here listening to Jumpstart Nature. That tells me one thing. You are a nature lover., and I bet there’s a landscape near you that you absolutely cherish.

[00:03:09] It might not be famous. It might even be overlooked. It’s beauty and importance unnoticed by most, but you see it, you feel it. You have a deep personal connection with that place. We all have these places, but my next question is the most important one. Is that land that you love threatened by habitat loss?

[00:03:27] Human encroachment or construction? Is that land protected? If not, why not? But first let’s paint the picture of Coyote Valley a bit more to make it real for you.

[00:03:38] Michael Hawk: I moved to San Jose in 2011. So San Jose is considered the heart of Silicon Valley, where tech companies employ hundreds of thousands of people. It’s part of the greater San Francisco metro area, which is home to nearly 10 million people.

[00:03:53] After I moved here, I hiked a hill very close to my house and I noticed this vast open space to the south. It was a valley with a mosaic of landscapes. There was agriculture, a river running through the middle of it, there was a massive wetland full of water just over the hill from where I lived. It looked beautiful.

[00:04:11] I wondered why it hadn’t been built in to suburbs and business parks like the rest of Silicon Valley. The iconic US 101 highway bisects the valley. But I was drawn to that wetland. I wanted to go explore it. I could see the mountain range on the other side of the valley. It’s called the Diablo Range, and it was poking its way across the valley floor almost connecting to the Santa Cruz foothills on the other side, and the hills were dotted with massive and ancient oak trees, bay trees, buckeye, trees, and so much more.

[00:04:42] I slowly realized I’d lucked into moving to what was perhaps the last suburb to have been built next to Coyote Valley.

[00:04:49]

[00:04:49] Griff Griffith: That’s Michael Hawk, who you probably know as the founder of Jumpstart Nature and the producer of this podcast.

[00:04:54] He’s been telling me stories about Coyote Valley for years, and that we had to do a podcast episode about it. Well, he convinced me. To show you why you should know the story of this land.

[00:05:06] Nick Perry: So I grew up door to my grandparents. and they came here during the Great Depression when my grandpa did. He was actually a migrant farm worker from New Mexico.

[00:05:15] And so he would take me places to show me what Santa Clara County looked like before it was Silicon Valley, one of the places we would come to.

[00:05:22] As we would keep driving south, out of San Jose and to Coyote Valley, and he’d be like, Nicholas, this is what Santa Clara County used to look like. This was a paradise before it all got developed. And this is, this is your glimpse of what it was before. And it just really fascinated me. I was like, wow, this place still exists. My name is Nick Perry. Coyote Valley Project Director for the Santa Clara Valley Open Space Authority.

[00:05:44] Griff Griffith: Nick has a deeply personal relationship with this paradise.

[00:05:48] Just like Apple before, Cisco Systems, a global tech giant, wanted to relocate their headquarters to Coyote Valley.

[00:05:55] Griff Griffith: Nick, just a high school student at the time, couldn’t stand to see his paradise turn into another sprawling low rise office campus.

[00:06:02] Nick Perry: I created a Save Coyote Valley website, because I thought, well, you know, like there’s someone who needs to advocate for this place. When I created my little website, it got a lot of attention. And as a teenager I was getting emails from people, who were angry at me. I was just rereading some of them because I printed them out and put them in this folder that I’ve had since high school. But some of them were like, how could you stop progress?

[00:06:24] Griff Griffith: Politicians and real estate moguls like to call this “development”. You know, take some useless land and make it useful.

[00:06:32] Develop it. To developers, usefulness often starts with a large construction contract. For politicians, it starts with tax revenue, but there are other ways to value land too.

[00:06:45] Andrea Mackenzie: these kinds of large extensive open spaces

[00:06:48] act in our favor. They act to help us build resilience to these increased climate challenges by buffering lands from massive wildfires, soaking up storm waters as they come through, storing water underground, which we can tap during times of drought. These are the gifts that nature keeps giving us for free. And increasingly we’re putting a price on those and we’re understanding the value of them. But it’s really important to educate the broader public and decision makers so that piecemeal decisions aren’t made that undercut these services that nature is providing us

[00:07:28] Griff Griffith: That’s Andrea Mackenzie again. She’s talking about ecosystem services.

[00:07:33] There are so many things that nature does for us that we often take for granted and overlook. These services don’t show up on corporate balance sheets, but if they go away, they show up as natural disasters. They also show up in the form of increased insurance rates, increased food prices, pollution, floods, and wildfires. But it’s easy for a developer to discount or ignore these free services when advocating for their projects.

[00:07:55] After all, most of those costs I just mentioned, aren’t felt by the developer because they are paid by others often months or years later. In economics, these are called externalities. And unfortunately, are often overlooked.

[00:08:08] But in order to solve this, we must first understand how the land benefits us

[00:08:13] Megan Fluke: the Coyote Valley campaign, which you know, is a multi-generational campaign that started decades ago. The effort really seemed like a campaign to protect this landscape for the sake of the landscape, and that it was beautiful and it was open space and open space ought to be protected.

[00:08:31] The way that it evolved is we started to learn so much more about Coyote Valley, that it was an essential wildlife corridor for large mammals between the Santa Cruz Mountains and the Mount Diablo Range, that it protected San Jose’s water quality and protected San Jose from flooding. Just a whole host of other benefits that I could riddle off.

[00:08:53] The way that the goal evolved is that as we learned more about all of the value that Coyote Valley provides, that development in Coyote Valley just didn’t make sense both from a climate change perspective and also from an economic perspective.

[00:09:08] Griff Griffith: Megan Fluke, who we heard from in the intro, is the former Executive Director of Green Foothills, a non profit that advocates to protect open space and natural resources in the South San Francisco Bay Area.

[00:09:20] Green Foothills was among many other local advocacy organizations that have played a critical role in working to protect Coyote Valley, but ecosystem services aren’t just about the economic benefits of nature.

[00:09:31] It also includes the cultural and spiritual benefits.

[00:09:35] Chairman Lopez: My name is Valentin Lopez, and I’m the chairman of the Amah Mutsun Tribal Band. I’m also president of the board of directors of the Amah Mutsun Land Trust. Amah Mutsun Tribal Band is comprised of the descendants of the indigenous peoples that we’re taking the missions San Juan Bautista and Santa Cruz. Our territories began at the very southern end of Coyote Valley. History identifies our tribe as hunters and gatherers. And, uh, that’s quite insulting, and nothing can be further from the truth. Our people were very active stewards of the land. You know, our creation story takes place just directly west Coyote Valley, and if you look west, you would see the peaks of the Santa Cruz Mountains, and one of the tallest peaks. That’s Mount Umunum, and that’s the location of our creation story. And in our creation story, Creator gives us the responsibility to take care of Mother Earth and all living things. And so for us, all living things are the plants, the trees, The wildlife, the birds, the fish, the four legged, the finned, but then also the rivers, the mountains, and, the view sheds.

[00:10:54] Those were all our responsibilities and our people took it very seriously. We had the responsibility to ensure there was adequate foods for the fish, for the migrating birds, for the deer, the elk, the bear, etc. That was our responsibility to take care of those cultural resources, those food resources for all species.

[00:11:13] Griff Griffith: The depth of connection that indigenous people have with this land is hard for most non indigenous people to fathom. And modern society is often dismissive of traditional ecological knowledge because it doesn’t use the same terminology as Western science.

[00:11:26] And isn’t written up in pricey academic journals.

[00:11:29] Chairman Lopez: when I was in college, I went and looked at the words science and, because I knew that archaeology and chemistry, or biology, you know, I understood what those words meant, but science, what the heck did science mean?

[00:11:42] So I went to the library and looked it up, and science is the study of knowledge. And so when I look at it that way, all of our ancestors were scientists. You know, they’d studied how the plants interconnected, how they studied about the winds.

[00:11:56] They studied about the rains. They studied about the fog, the shadows. we knew that when the insects, nested in the ground, you know, what their nesting periods were so we wouldn’t burn during that time.

[00:12:07] Griff Griffith: You know, science is one of those terms we hear and use all the time, but I decided to look up the definition, just like Chairman Lopez did. Here’s what I found. The systemic study of the structure and behavior of the physical and natural world through observation, experimentation, and the testing of theories against evidence obtained. Over thousands of years, indigenous people had to study, observe, experiment, and test in order to thrive.

[00:12:49] As you might guess, open space adjacent to a prosperous area like Silicon Valley is in high demand.

[00:12:56] And And demand to develop in Coyote Valley has been consistent. Dr. Stuart Weiss is Chief Scientist at Creekside Science. He’s been working on various biology and ecology projects in and near the Valley for many years.

[00:13:10] Stu Weiss: Over the years, there’s just been all these development proposals in Coyote Valley. So back in the eighties, it was Apple and Tandem Computer wanted to put in a huge development in the late nineties cisco wanted to put their world headquarters right down there as part of Coyote Valley Research Park. And then in the mid two thousands people were pushing to have a city, developed on the valley floor. And one of the things I noticed is that every time a Coyote Valley development started getting some momentum, the economy would crash or there’d be a tech crash, and the plans would go away for a few years.

[00:13:51] I just thought that was an interesting leading economic indicator kind of wish I had based my stock investments on that

[00:14:00] Griff Griffith: the demand to develop Coyote Valley was so high that huge projects were pursued. Each one was complex and costly.

[00:14:07] And thankfully, there was a little luck that prevented these projects from proceeding. In fact, the Apple project fell through during the mid eighties, not just because of an uncertain economy, but Apple’s internal politics led to Steve Jobs being forced out.

[00:14:20] Apple ended up selling the land to another developer. And this is one of the first lessons that Coyote Valley can teach us. Perseverance is critical because you never know what is around the corner.

[00:14:31] Griff Griffith: But even as the development projects fell through, other threats remained.

[00:14:35] Dr. Weiss, while in graduate school, had been studying the Bay Checkerspot butterfly. The small butterfly used to be abundant across much of The San Francisco Bay Area. But at this time, only a few small populations remained, and one of those populations was in some hills adjacent to Coyote Valley.

[00:14:52] These grassland hills were grazed by cattle, so some of the researchers decided to fence off a section and see what happened. To their surprise, the fenced off area was taken over by non native Italian ryegrass. The soils in those hills were made of an ancient serpentine rock, which is known to be nutrient poor. And only specifically adapted plants can grow in serpentine soil. Why was the Italian ryegrass here when it struggled to grow so well in other serpentine areas?

[00:15:20] Stu Weiss: I went back to graduate school at Stanford to get my PhD. And I was sitting in a ecosystem ecology class, and the professor Peter Vitousek gave a lecture about something called dry nitrogen deposition. And it was like the light bulb went off in my head and I think it was the magnitude of the Las Vegas strip by the time it was over.

[00:15:46] Stu: And I made all the connections because I’ve been staring up at the smog cloud for about a decade at that point

[00:15:54] And then few back of the envelope calculations and it’s like, yeah, that’s a lot of nitrogen coming down. And that was the moment when I knew that this was an amazing connection here.

[00:16:06] Griff Griffith: It took Dr. Weiss a few years putting the research and science together. He needed to find out why the grazed areas showed more native plants and stronger butterfly populations, and why Italian ryegrass was growing so much better in those areas that were not grazed.

[00:16:20] Stu: And then I published a paper in 1999 that described the phenomenon.

[00:16:25] It’s called Cars, Cows, and Checkerspot Butterflies. And it’s become a bit of a citation classic at this point because I had made a really direct connection between the nitrogen deposition and the loss of biodiversity.

[00:16:38] Griff Griffith: Dr. Weiss was able to show that emissions from cars were fertilizing nearby lands. It was turning those nutrient poor soils into soils that could support invaders like ryegrass. His math showed that as much as 6 kilograms, or 13 pounds, of nitrogen was being applied to an acre of land every year.

[00:16:56] It turned out that the cattle were preferentially eating the invasive grass, due in part to how the grazing was managed. That’s right. Cows were actually helping biodiversity in this unique environment. This is a fascinating story that we looked at in more detail

[00:17:10] in Nature’s Archive Podcast Episode 37. But this discovery and the research that Dr. Weiss did was a key to unlock some of the biggest steps to protect Coyote Valley.

[00:17:21] In 1999, when Dr. Weiss’s paper was published, there was also a proposal to build a power plant in the north end of Coyote Valley.

[00:17:28] Stu: There was a proposal for the Metcalf energy center, 600 megawatt gas fire power plant,

[00:17:34] And it’s a large source of nitrogen oxides.

[00:17:39] The U S Fish and Wildlife service and the California Energy Commission told the proposers of the power plant that they had to do something, we have to mitigate for this.

[00:17:50] Griff Griffith: Many federal, state, and sometimes even local governments require projects that cause environmental harm to offset that harm in some way. In this case

[00:17:59] Stu: they really wanted the power plant and, we’re willing to put out a lot of extra what seemed to me have a lot of extra money, but it’s a half billion dollar project.

[00:18:08] 10, $20 million extra for mitigating was part of the capital costs and they were willing to do it. And we really wanted a precedent for mitigating for nitrogen emissions, because we figured we could start leveraging that. So that went through. In 2003, we have this ceremony dedicated in the Metcalf’s Energy Center Ecological Reserve.

[00:18:33] Stu Weiss: the mitigation for the Metcalf Energy Center turned out to be 131 acres of habitat conserved,

[00:18:41] Stu: So we had the precedent.

[00:18:42] Griff Griffith: This precedent led to 600 additional acres preserved when the US 1 0 1 highway was widened. Eventually, an 1800 acre hillside preserve was also developed This allowed local groups to show the public and the politicians this gem that people were driving by every day, but not noticing -until now. The views from the ridge were both breathtaking and informative.

[00:19:05] Advocates and biologists could tell the story of the land.

[00:19:08] They could show people super blooms of native flowers, the wetland below and how the highways bisected this narrow valley.

[00:19:14] People could easily see just how close the other range was across the valley.

[00:19:20] Andrea Mackenzie: One of the earliest Discoveries about Coyote Valley and why it was and is irreplaceable landscape is we realized that it was the last viable land connection or bridge connecting the Santa Cruz Mountains and the Diablo Range. A million acres of habitat in those two ranges. The success of those habitats depends on the gene flow and wildlife able to move between those two mountain ranges. So by protecting it, it’s the missing puzzle piece that allows us to avoid extinctions and to, improve the biological conditions for many, many species, some of which are found nowhere else in the world.

[00:20:06] And it’s easy for people to understand. It’s compelling. You have charismatic megafauna, as we like to call them, the mountain lions and the bobcats and the foxes and the golden eagles and the bald eagles that are all active in this landscape. And so they become really the salespersons, the ambassadors for protecting this landscape.

[00:20:28]

[00:20:28] Griff Griffith: I like to call those charismatic animal species

[00:20:31] ambassador animals. And if this story of landscape linkages and connectivity sounds familiar, it’s because we did a deep dive in the episode we called The Age of Connectivity.

[00:20:42] Biologists and the general public, like you , are recognizing that the impact of fragmented habitats goes way beyond tragic roadkill.

[00:20:50] Ambassador animals are a critical part of many successful conservation efforts. The charismatic mountain lion of Hollywood, P 22, did so much to sway public opinion, resulting in the construction of the Wallis Annenberg Wildlife Crossing in Los Angeles.

[00:21:04] And these types of stories are showing up more and more all around the world.

[00:21:15] Nick Perry: right now we have about 1, 500 acres of the valley floor permanently protected.

[00:21:19] Griff Griffith: That’s 1500 acres protected in addition to a few thousand acres in the bordering hills. The Santa Clara Valley Open Space Authority sees a bright future ahead, but protection of this landscape is just one important step in Coyote Valley’s journey. They are developing a comprehensive master plan that incorporates land use agriculture, habitat restoration, and access. And to do this well, they are engaging with the public, landowners, the Amah Mutsun, and other local tribes, as well as other users and stakeholders. Many more steps lie ahead. Some of the improvements will happen quickly, but some habitats may take years or even decades to fully recover.

[00:21:58] Andrea Mackenzie: Native American ethos and philosophy is that we should be thinking seven generations ahead. And conservationists know this. They feel it in their, bones that we must be thinking long term

[00:22:12] Griff Griffith: remember earlier when I asked you about the local landscape that you love? Chances are it needs some help just like Coyote Valley.

[00:22:20] And there are so many lessons to be learned from this story. So what lessons can our guests share from this experience in Coyote Valley?

[00:22:27] We already mentioned the importance of perseverance, even when times look tough. Unexpected turns led to development projects falling by the wayside. Megan Fluke elaborates on this.

[00:22:37] Megan Fluke: What was surprising was that at some point we realized that the energy to pave over Coyote Valley and industrialize Coyote Valley really was just coming from a handful of people who had hopes for an industrial and urban city on this landscape.

[00:22:55] It almost felt like the Wizard of the Wizard of Oz for those that know that story. Once we looked behind the curtain, this seemingly, you know, sort of formidable opposition that just we couldn’t really grasp, but we didn’t really know where all this, you know, energy was coming from. This opposition really wasn’t as powerful as we thought.

[00:23:15] the campaign to protect Coyote Valley not once felt hopeless. It felt hard. It felt overwhelming, maybe confusing at times, but not hopeless. we pushed through and we persevered because that’s what advocates do, and we had the community on our side. I

[00:23:33] Griff Griffith: Getting the community on your side is another critical lesson. Ambassador animals can help with that, but you need to be sure people are connected to the land and the vision.

[00:23:41] Megan Fluke: One way that we’ve found to keep people energized is connecting them to the land. One of my favorite quotes is from the naturalist and writer Obi Kaufmann, people protect what they love and love what they know. The way that I found that’s helpful to keep people energized is through education and community connection And. Frankly, having a good fight every so often also energizes people too.

[00:24:08] Stu: We started taking people up to Coyote Ridge to see it, in 2003, I invited all of the elected officials in Santa Clara county to come take a tour and we had it set up so they would show up we’d shuttle them to the top in our four wheel drive vehicles, . And we’d have them for a few hours.

[00:24:28] We’d feed them like this gourmet lunch, then we’d send them on their way back down the hill. And it was transformative. We ended up with some real champions in the elected bodies who realized that, hey, we’re Santa Clara county. We do things right.

[00:24:45] Griff Griffith: Finding champions is also critical, whether it be elected officials, energetic advocates, or existing landowners.

[00:24:52] Nick Perry: Coyote Valley is an amazing place for agriculture. It has great soil, good weather. Agriculture definitely faces economic challenges, but there’s really great potential to help reestablish local agriculture in places like Coyote Valley.

[00:25:08] Griff Griffith: And feel free to toot your own horn once in a while, too.

[00:25:12] Andrea Mackenzie: We acquired a piece of property and opened it to the public in 2015, 350 acres called the Coyote Valley Open Space Preserve. Right before we opened it to the public, we had convenings there and community celebrations to bring many, many people out. People actually drove 45 minutes from San Francisco to come check out this new landscape. And it became a wonderful gathering spot for people to learn about Coyote Valley.

[00:25:46] That would be just a fraction of the conservation achievements we’ve achieved since then. I kind of liken it to this analogy of a, a small bird sticking out its chest and trying to appear bigger than it really is. That’s the kind of behavior that, that we engaged in to show people this was a small but really, really important

[00:26:06] Open Space Preserve, and when we opened it to the public and invited them to come in, they started to get a taste of what this amazing landscape, which had been forgotten for so long, and was surely going to be developed over time, and now belonged to them. What it could be if we thought bigger.

[00:26:25] Griff Griffith: And too often, Indigenous knowledge and partnership is missed.

[00:26:29] Chairman Lopez: I think that what’s really important is for the land managers to recognize the importance and the contributions of traditional indigenous knowledge, you know, our knowledge of the use of fire for cultural burning, not just prescribed fires to reduce fuel, but the importance of fire for, you know, enhancing and developing cultural landscapes. Restoring native plants.

[00:26:55] we’ve talked about these authorities and we’re actually working with them on a number of these initiatives as such. we feel that we have a good relationship with them today. And, and that we are working with them and they do have an appreciation for indigenous knowledge.

[00:27:10] I’d like people to recognize that we suffered through three the brutal periods of colonization. They were very difficult to us. And we people to know that we do not look at them as being the perpetrators to what happened to us. We don’t blame them. But what we ask for them to recognize, how much they benefited from that horrific history. And to recognize that the tribes today, especially the unrecognized tribes, but all tribes today, to work with tribes to help them restore their culture, restore their spirituality, restore their identity, and restore their, their landscapes, and to work with us to heal and recover from the past, And there’s a number of ways they can do that, you know, by supporting tribes in a lot of ways. But like, say for example, our land trust. Our land trust is a non profit. We can only do so much work, according to the amount of, money that we can raise. And so if they can help our land trust through donations that would go a long way to helping Mother Earth and helping our tribe.

[00:28:26] Griff Griffith: And we need to remember an important saying in conservation.

[00:28:30] Megan Fluke: advocates at Green Foothills like Brian Schmidt and Lenny Roberts would tell me ” the wins are temporary, but the losses are permanent”

[00:28:36] Griff Griffith: The wins are temporary because there’s always a new push to develop or purchase land or rezone it.

[00:28:42] Nick Perry: If you look back at the history, Coyote Valley was, I think, first zoned by the city of San Jose for development in 1960 in the And then in 1975, they rezoned it back to agriculture because, you know, people started to advocate that maybe it wasn’t best to continue to sprawl out.

[00:29:00] but then in 1984, they rezoned it back to development when companies like Apple wanted to build here. And that was the case until 2021. So, tides can change.

[00:29:09] Griff Griffith: That’s perhaps the last lesson of Coyote Valley. It’s important to constantly remind people of the value of their land because it’s all too easy for it to be taken for granted. As Megan Fluke said, the wins are temporary, , but the losses are permanent. So think about the special land near you and what you can do to support it. Which groups can you join? Which city council meetings can you attend?

[00:29:31] Perhaps you can organize a hike, birdwalk, or bioblitz to and show others the value of the land. Just get started. And big thanks to our guest today, Andrea Mackenzie, Megan Fluke, Nick Perry, Stuart Weiss, and Chairman Valentin Lopez.

[00:29:45] Chairman Lopez mentioned the Amah Mutsun Land Trust. I love Land Trust because they give us another opportunity to connect, to save, to be a hero, to have a relationship with the land. You can learn more about the Amah Mutsun land trust at www. amahmutsunlandtrust. org. We have links to them and all of our other guests in the show notes at jumpstartnature.com/podcast.

Jumpstart Bonus: Top 10 Favorite Species with Griff Griffith, Michelle Fullner, and Michael Hawk

What do parasitic plants, 600 year old oak trees, salmon, and hoverflies have in common? Well, they are some of Griff’s, Michelle Fullner’s and my favorite wild organisms!

One of the species mentioned today – a hoverfly. And if you look closely, you can see producer Michael’s outline in it!

Today’s episode is a fun conversation with Michelle Fullner, Griff Griffith, and myself, Michael Hawk, where we advocate for our 10 favorite animals and plants. We each bring three species to the conversation…well, not physically. And we had a bit of a game to decide who got to pick the 10th one. All I’m saying is that I still think that aphids would be good at soccer, but you’ll have to listen to hear what that’s about.

This idea was all Michelle’s – and if you don’t know Michelle, she’s the host and producer of the Golden State Naturalist podcast, which is a fun and entertaining California-centric nature podcast. Her fourth season is about to launch, and she plans to cover topics that I know you’ll love – wildlife crossings, coastal wetlands, red-legged frogs, and much more. Be sure to check out her podcast and follow her social media, too.

And looking ahead, Jumpstart Nature is in the late stages of three new episodes for this fall, covering invasive species, outdoor cats, and an inspiring land conservation story that succeeded against all odds. And if you’re listening to this on the Nature’s Archive feed, well, we have plenty of fun episodes coming too – covering topics ranging from wildlife forensics to ants!

[00:00:00] Griff Griffith: It’s hard to even imagine how many salmon there used to be to anybody who’s been born after, you know, 1950. We can’t even, we can’t even fathom how many there were. And. Back in the day, people say there’s so many, you can walk across their backs. There was so many, you could dance across, you could break dance across her back. 

[00:00:14] Michael Hawk: So what do parasitic plants, 600 year old oak trees, salmon, and hoverflies have in common? Well, there’s some of Griff’s, Michelle Fulner’s, and my favorite wild organisms. So today’s episode is a fun conversation with Michelle, Griff, and myself, Michael, where we advocate for our 10 favorite animals and plants.

[00:00:34] We each bring three species to the conversation. Well, not physically, but virtually. And if you do the math, there’s three of us times three species. And you might be wondering, well, how do we get to number 10? So we had a bit of a game to decide who got to pick the 10th species. And all I’m saying is I still think that aphids would be good at soccer, but you’ll have to listen to hear what that’s all about.

[00:00:56] This whole idea was Michelle Fulner’s. And if you don’t know Michelle, she’s the host and producer of Golden State Naturalist podcast, , it’s a fun and entertaining California centric nature podcast, but the lessons in it span way beyond California. Her fourth season is about to launch and she plans to cover topics that I know you’ll love wildlife crossings, coastal wetlands, red legged frogs, and so much more.

[00:01:20] So be sure to check out her podcast and follow her social media as well. And looking ahead, Jumpstart Nature is in the late stages of three new episodes for this fall. We’re going to be talking about invasive species, outdoor cats, and there’s an inspiring land conservation story that succeeded against all odds that you just have to hear about.

[00:01:39] If you’re listening to this on the Nature’s Archive feed, well, we have plenty of fun episodes coming too. We’re covering topics from wildlife forensics to ants and much more. So, all right, here we go.

[00:01:49]

[00:01:49] Michael Hawk: So from this moment forward, no mistakes.

[00:01:53] Griff Griffith: Yeah,

[00:01:53] Michelle Fullner: Perfection is what we demand here. Alright, how’s everybody this morning?

[00:01:58] Grand 

[00:01:59] Michael Hawk: Getting there.

[00:02:00] Michelle Fullner: You getting 

[00:02:00] there? 

[00:02:00] Michael Hawk: at the grand level, but but not bad either. Somewhere in between.

[00:02:03] Michelle Fullner: We’ll get you a crazy straw for your coffee. Put it in, in, you know, a helmet. To get gravity working in your favor.

[00:02:09] Michael Hawk: Like those beer helmets. You see people it’s sporting events

[00:02:12] Michelle Fullner: With a straw,

[00:02:13] Michael Hawk: Yeah.

[00:02:13] Michelle Fullner: you’re gonna be good to go, definitely. 

[00:02:15] Well, all of us, I think have some roots in California, we’ve spent a lot of time kind of learning about the space, learning about , the world around us here. And so I wanted to bring us together and talk about some of our favorite species.

[00:02:28] . So I was going to go ahead and just kick us off and then we’ll just take turns. And then because there’s three of us, we’re making a top 10 list. So let’s get our top 10 favorite species, native species. And then because there’s three of us, that only brings us to nine. So we have a problem.

[00:02:42] Michelle Fullner: So each of us have four favorites and to choose which one is our number one, they’re going to have to compete. And we’re going to have to figure out which one is going to win in a game. And that game is yet to be determined by being drawn out of a hat. So a sport, and we’ll see which of our species would win.

[00:02:59] Griff Griffith: not a video game.

[00:03:00] Michelle Fullner: Not a video, you know, I should have put professional gaming in there, but I didn’t. Video gaming.

[00:03:06] Griff Griffith: I’ve never even 

[00:03:06] really seen a video game.

[00:03:07] Michelle Fullner: Okay.

[00:03:08] Griff Griffith: have. That’s it.

[00:03:09] Michael Hawk: I was really hoping for some truly exotic sports like underwater polo or, you know,

[00:03:14] Michelle Fullner: Oh yeah. They didn’t get that exotic.

[00:03:16] Michael Hawk: Ah,

[00:03:17] Michelle Fullner: mean, not just the top most televised sports for sure, but not super exotic ones either. We’ll see. We’ll see what 

[00:03:23] Michael Hawk: my aquatic beetle, my aquatic beetle may have a difficult time. I was planning on that underwater polo.

[00:03:29] Michelle Fullner: It was going to take us, it was going to take the competition away. You’re going to win us. Okay. So I’ll kick us off and then we can just kind of go through. We’ll go me, Griff, Michael, until we get to our number one spot and figure out which one’s going to win.

[00:03:41] Michael Hawk: sounds good.

[00:03:42] Michelle Fullner: All right. So, so number 10. This is number 10.

[00:03:45] , my first one that I have here is , it’s a butterfly and it is native to an area where I live and maybe, actually, I don’t think Michael’s in the range of it. Michael might be just south of the range of this butterfly, but it’s a Northern California butterfly that I love very much. And it’s beautiful blue and it has on the underside of its wings it has these beautiful like orange and white sort of spots and the back is almost like this black and then iridescent blue and the males are like more blue than the females.

[00:04:15] And it’s the California Pipevine Swallowtail Butterfly and it is gorgeous. Like they’re big, they’re beautiful, they’re very like to me charismatic. So I just really love seeing them in the forest. And I see them a lot of times in like riparian areas. I see them in Auburn all the time. And when I’m in Auburn, when I’m hiking there, the other thing I see is their host plant, which is the California pipe vine, sometimes known as the Dutchman’s pipe, which is the only place where the little caterpillars.

[00:04:44] Can grow up. So it’s their, it’s their food of choice and they love living on the Dutchman’s pipe. They eat it and they do something else that’s really cool. So I talked a little bit about their bright colors and maybe you guys can help me pronounce this word because I’m not actually sure how to pronounce it.

[00:04:58] Is it aposemitism? You guys know this word?

[00:05:01] Griff Griffith: I always say aposemitism,

[00:05:03] Michelle Fullner: Aposemitism?

[00:05:03] Griff Griffith: but that’s just me.

[00:05:04] Michelle Fullner: I, I heard somebody pronounce it the other way, but I don’t actually know.

[00:05:08] Griff Griffith: Yeah. I don’t think I’ve ever heard anybody pronounce it besides me and a couple other podcasters. So,

[00:05:15] Michelle Fullner: Thank you. Okay, so my default was aposemitism, and then I heard an entomologist say aposemitism, and so

[00:05:21] Griff Griffith: oh, let’s go with that then. Let’s

[00:05:22] Michelle Fullner: I don’t know. Okay, 

[00:05:23] Michael Hawk: All right. We’ll, we’ll get our team of fact checkers to

[00:05:25] Michelle Fullner: yeah, the

[00:05:26] Griff Griffith: where’s the all bugs by the Kevin? We just need to ask him.

[00:05:29] Michelle Fullner: There we go. There we go. That’s a great idea. So if anybody doesn’t know what aposemitism, we’re going to go with that, is, is basically you ever see those like really bright like frogs in the rainforest with these vibrant colors?

[00:05:41] They’re like poison dart frogs. Well, the bright colors Here’s the thing. This, the animal has, has an issue, right? So this animal is super poisonous and it’s like, I’m protecting myself by being poisonous, but that’s not going to help if the bird or the snake or whatever animal comes and eats it and has no idea that it’s a poisonous animal.

[00:05:59] So , the creature has these bright colors to let everybody know, Hey, I’m poisonous, don’t eat me. And that’s called aposematism. 

[00:06:07] Michael Hawk: they’re teachers. 

[00:06:08] Michelle Fullner: So these 

[00:06:09] butterflies, 

[00:06:09] Griff Griffith: dogs? I thought they were colorblind. They don’t get the scoop on this or what?

[00:06:13] Michelle Fullner: that’s a great question. 

[00:06:15] Griff Griffith: how many other animals are colorblind

[00:06:16] Michelle Fullner: we have like amazing color vision, humans have like some of the best color vision, birds are better than us, but like humans have really great color vision, but also a lot of animals that we think of as colorblind, it’s not like grayscale black and white type colorblind, they have some colors. So I

[00:06:32] Griff Griffith: Maybe all the important colors, like the poison colors.

[00:06:35] Michelle Fullner: I wonder if it’s like, you know, dogs can see orange or whatever it is. I’m not sure. Had to look that up.

[00:06:41] Griff Griffith: Oh, what an interesting question.

[00:06:43] Michelle Fullner: Yeah. Yeah. So I love that these, these butterflies do this because they’re just letting everybody know, Hey, don’t mess with me. I have these bright colors. Don’t eat me. And it’s because they get the toxicity from their host plant. They get it from the California pipeline. It’s a super toxic plant. And , the caterpillars chow down on that.

[00:06:57] And then it’s like their body is imbued with this toxin.

[00:07:00] Griff Griffith: Puts a whole new spin on art you are what you eat, huh?

[00:07:05] Michelle Fullner: Absolutely. 

[00:07:06] Michael Hawk: Well, I think you hit, you hit an interesting point there too, because you said birds have really good vision and a lot of them can even see like into the UV spectrum and that would be the primary predator of a butterfly would be birds, so it works for them.

[00:07:18] Michelle Fullner: that’s a great point. And it makes me wonder if there’s even colors designed for birds to see on the butterfly that we don’t even see.

[00:07:24] Griff Griffith: Oh, and you know what? Dogs and wolves, if they can’t see those colors, the dose is probably, you know, dose makes a poison. Like they’d have to eat hundreds of butterflies before it made a difference. Maybe they don’t need that color vision.

[00:07:36] Michelle Fullner: That’s a great point. Maybe it’s just not even important to them. It, maybe it would like knock out a bird, but it would barely touch a dog.

[00:07:41] Griff Griffith: Size matters.

[00:07:42] Michelle Fullner: Yeah, for sure. Okay, that’s interesting. So how to help these animals? Okay, so if you live in the native range, you gotta look up a range map. It’s, it’s northern California, and I know it’s a lot of northern California.

[00:07:53] I don’t know the exact parameters of where these butterflies live.

[00:07:56] Michael Hawk: They’re in Arizona as well. I, there’s a different there’s a different pipe vine down there.

[00:08:00] Michelle Fullner: here’s the thing though, This, our subspecies is only here. 

[00:08:04] So I was like, I was, had to be extremely on brand for this and I chose only endemic species. So

[00:08:10] all of, all of mine are only endemic to California. But Michael, you’re right.

[00:08:14] Cause there is

[00:08:15] Griff Griffith: What does endemic mean for our listeners?

[00:08:17] Michelle Fullner: So endemic is it’s only within a certain range. And so in my case, I’m choosing only Organisms that are endemic to California. And this is even a little bit narrower than that because it’s just Northern California. So,

[00:08:29] Michael Hawk: stay, staying on brand for, for me anyway, I love to get into the nuance. So you’re talking about a subspecies.

[00:08:35] So there’s pipevine swallowtail as a species. And then there are certain subpopulations that are a little bit genetically different and have slightly different behaviors or preferences.

[00:08:44] And the one you’re focusing on is the Northern California specific subspecies.

[00:08:49] Michelle Fullner: exactly. So yeah, there’s a whole bunch. I know in like the, the Eastern United States, and I want to say that they’re more in the Southeast, but they also, I think they get up pretty far North too. I’m not sure their exact range over there, but they’re not obviously the California subspecies. So yeah, those are, those are the ones that we have here.

[00:09:05] And if you live In Northern California, where these butterflies also live, a way to help them is to plant their host plant, which is the Dutchman’s Pipe or the California Pipeline, however you want to call it. Both are common names for it. But one of the things that’s good to know about this plant is that everybody talks about how slow it grows.

[00:09:22] So it’s a very slow growing plant, but you can accelerate it a little bit by giving it a lot of water when it’s establishing. So it’ll grow a little faster if you give it a good amount of water. I’ve had mine for, this is the third year it’s been back there, I don’t give it a lot of water because it’s this weird spot in my side yard that I just never go over there. So it’s grown really slow, but this year it like exploded. It’s on this trellis, it’s a vine, so it, it, it’s really great for the side yard, things like that, where it’s like, they say, plant it where the, the bottom of it. Will not get direct sunlight, but the leaves, it will grow into sunlight. So that’s like the ideal conditions for this.

[00:09:57] It’s great for taking up, you know, a wall type of space, putting it on a trellis, if you’ve got like a small space for it. And then after a couple of years is when it really starts to flourish usually, but you can accelerate that by, you know, giving it a little extra water.

[00:10:11] Michael Hawk: It’s a cool looking plant too.

[00:10:12] Michelle Fullner: It is, and it’s got the craziest flowers.

[00:10:14] They, it’s called the pipevine because the flowers look like these pipes. And they’re pollinated by what are they? What are they pollinated by?

[00:10:21] Michael Hawk: No, sorry.

[00:10:22] Michelle Fullner: They’re like little gnats, right? They’re pollinated by gnats, I’m pretty sure. Super 

[00:10:25] Griff Griffith: That’s what I, that’s what I remember. Anyways, I’m not looking it up.

[00:10:28] Michelle Fullner: I think so. And then, if you open one of the flowers up, you see a bunch of dead gnats in there. So people actually thought these flowers were carnivorous for a while, but they’re not. The gnats just can’t always find their way out. It’s just unfortunate for them.

[00:10:39] Griff Griffith: Oh, it seems like someone’s got some more evolving to do.

[00:10:42] Michelle Fullner: I know, like, let’s take advantage of that situation. Alright, let’s kick it over to Griff. That was my first one. That was number 10.

[00:10:48]

[00:10:48] Griff Griffith: so I picked my animals based on my relationships with them, not those kinds of relationships, but like, how I’ve experienced them throughout my life. And so most of them stem from my childhood. So not necessarily my favorite species, but they are the species that led me into conservation.

[00:11:04] And the first one I want to talk about. Is turkey vultures. So I always grew up on the edge of suburbia in the Bay area. So I was one of those kids. You’ll hear a lot of older conservationists my age say this from California. I was one of those kids that pulled out the stakes when I knew they were going to build, because I knew what that meant.

[00:11:18] That meant that my Creek was going to get put underground. That meant my pond was going to get drained. That meant terrible things were going to happen to the animals I liked. And I had everybody in my neighborhood convinced that I could tell the turkey vultures apart, and then I had them all named. That was a lot, but everybody fell for it. And so the one I remember the most was Big Red and I’d watch Big Red. He was the biggest one to me. And or she, probably she, but big red would circle around and I just loved turkey vultures. And I always thought they were circling around because there was something dead in the field across the street.

[00:11:48] So I always went over there and looked. And then later I found out that’s not true. Turkey vultures have a great sense of smell, but they won’t give up a meal. So when they’re circling, they’re actually rising on a warm air current that is spiral like so many other things in nature. It’s a spiral, just so interesting.

[00:12:05] And then, so I’d watch these and they had that wobbly flight, like they’re hitting turbulence all the time, but they barely ever flapped. Super cool to watch. And so I’d make up stories about them, blah, blah, blah. And so I finally became, I finally got my wildlife career started when I was 12, like on my birthday.

[00:12:19] And I volunteered at the Suisun Wildlife Care Center. And one of the first animals that I had to go get to be weighed was a turkey vulture. So the uh, the older volunteer was like, send the, this is the 80s. This would never happen today. So 12, if there’s a 12 year old listening and getting excited, you won’t be able to do this nowadays.

[00:12:36] This is the 80s. So they’re like 12 year old, go get the turkey vulture out of the pen and bring it in here.

[00:12:41] Michelle Fullner: These are large

[00:12:42] Griff Griffith: I. They’re large birds. I’m 12. I knew to put a towel over its head. Cause when birds can’t see, they get less stressed. So if you ever have to rescue a bird, cover it with a cloth or something.

[00:12:52] So I went in there and I went to go throw the towel over it and I missed, and the turkey vulture vomited and moved its, moved its head and spread vomit everywhere. And at that moment, I knew that this was my very favorite bird because I was 12 and I loved gross, and that was the grossest thing I’d ever seen.

[00:13:12] So I ran back inside and I was like, Oh my God, it threw up all over me. And the volunteer was like, Oh, that’s right. They do that. So I went back out there. I got it. And been in love with with vultures and wildlife care volunteers ever since. So, that was one of the things that was really cool and gross.

[00:13:26] The other thing is they. Pee oop, depending on how you want to say it, on their legs when, when it gets really hot. So birds don’t really have poo and pee so much. Like, you know, when you see bird poop, you see the brown part, the white part and the white part is kind of like the pee. So they pee oop on their legs to keep cool, which I thought was amazing.

[00:13:43] But also because they have such strong stomach acids and might also kill the bacteria on their legs, which I also thought was super fascinating. So 

[00:13:50] I was super. 

[00:13:51] Michael Hawk: with like reflectivity on their legs too. So it cools it off in the moment and then it keeps it a little more reflect,

[00:13:57] Michelle Fullner: Nice little whitewash.

[00:13:58] Michael Hawk: Like the

[00:13:59] albedo is higher than,

[00:14:00] um, 

[00:14:01] Griff Griffith: interesting. I can see how that would be, especially with the white and the puke or whatever. And then also they’re bald. Who can’t love that? And they’re not bald just because that looks cool. That actually has like, scientists believe an evolutionary function. So they’re not getting all the dead stuff on their their head.

[00:14:18] And like there’s some really cool Native American stories about how Turkey vultures lost their feathers. So if you want to look that up at your local tribe’s website, they might have a story, especially if you live in Turkey, well, there’s Turkey vultures and black vultures, but I’m sure the stories are pretty similar. So. I love them. And they have a sense of smell, which is really unusual for birds to have a strong sense of smell. So their sense of smell is even better than ours. So when you see turkey vultures dive and kind of cruise close to the ground, they’re going and they’re smelling for dead things when they do that.

[00:14:49] And that is also super fascinating. So I just think that they’re the coolest, most disgusting birds. And so if you have like a 12 year old who likes gross things and you’re trying to hook them in conservation, turkey vultures, and turkey vultures also are really closely tied to the land. Like all animals are, but like tied to what we’re doing on the land, our management, like lots of animals, but we can fix the turkey, like how turkey vultures are affected way easier than we can fix some of the other unhealthy relationships.

[00:15:17] And one of the best things you can do for turkey vultures is if you’re a hunter, switch to copper bullets, stop using lead bullets altogether so getting the lead out of hunting should be priority for all hunters.

[00:15:27] And I really like what like the Yurok tribe has done here locally is they have a hunters of stewards program because gut piles can help California condors, which are turkey vultures. And so getting the lead out could actually assist condor reestablishment in California. It can actually help scavenging birds like turkey vultures.

[00:15:49] And I think these are super easy for hunters to do. And so if you have, if you know, a hunter is really poor and can’t afford anything, but lead bullets, maybe. And you can get some copper bullets and trade them and take their lead bullets away. And say here you can have these instead. So those are just some of the reasons why I love turkey vultures.

[00:16:05] Also, the other really cool thing about new world vultures is they’re not related to old world vultures, even though they look so similar. It’s another fascinating example of convergent evolution, where two things in different parts of the world So, vultures in the new world are more closely related to seabirds, and that’s why they have such a great sense of smell.

[00:16:26] And then the ones in the old world, quote unquote old world, are more closely related to raptors, which is how the Oftentimes when you, when you see like raptors in North America and you’ll see turkey vultures on there, and I’m always like, what are they doing on there? But that’s wise because it’s a carry over from that old world tradition and accuracy because they are raptors over there.

[00:16:46] Michelle Fullner: Okay. That’s super interesting. And when you were talking about the turkey vultures, super great sense of smell, it reminded me about something super crazy about turkey vultures, which is that they don’t have a septum. So like that, that little bit of, of nostril, you know, like between your nostrils, a little bit of flesh right there.

[00:17:03] Turkey vultures don’t have that. And the reason why is because of that great sense of smell. So when they fly around, they’re getting air. passively passing through their nose so that they don’t actually have to sniff all the time. They can actually just have the air pass through and they can pick up this insanely small, like, parts per million amount of an odor of something, which is how they find, yeah.

[00:17:24] And so when they’re, I would imagine, They’re passively smelling just all the time, right? Cause they don’t have the septum. So when they’re circling, they’re, they’re riding that air current and they’re not even thinking about it. Like the air is just passing through. So if something was around, they would pick it up.

[00:17:37] Oh,

[00:17:40] Griff Griffith: about them is they don’t have a song. They don’t have a call. They have a hiss. That’s all they do is hiss. So if you wanted to like occupy some children for a long time, tell them to give them a hundred dollars. They go and hear a turkey vulture call and they’ll be outside for hours.

[00:17:55] Oh, wait, this is the eighties. I guess we don’t do that anymore. Right?

[00:17:58] Michelle Fullner: we need to 

[00:17:58] bring 

[00:17:58] Griff Griffith: the 80s, like, Oh, kids stay outside for all day long. That’s what my parents do. Yeah. Turkey vultures are awesome.

[00:18:04] Michelle Fullner: they’re rad. They’re super rad. Okay. Michael, let’s hear yours. What’s your number eight, Michael? What?

[00:18:13] Michael Hawk: species like turkey vultures. You can see the pipeline is a swallowtail. It’s a big butterfly and it’s always flitting around and it’s colorful. I’m going to go in the other direction and pick something that’s kind of ubiquitous, but easily overlooked.

[00:18:25] And I think that when we think of pollinators, we often think of bees and they get all of the press when it comes to pollination or most of the press, but my species, it’s actually a group of species, and I’ll, I’ll talk about one in particular. It’s the hover fly. So, some people know them as syrphid flies or flower flies, and I think they’re overlooked because they’re small, but they’re really colorful and they look like bees or wasps, and a lot of people will even call them sweat bees.

[00:18:51] So they’ll be patterned yellow and black, and you’ll see them kind of hovering around your flowers. And everywhere I’ve gone in the United States, I’ve found hoverflies, and usually multiple species, even in your backyard garden. So they’re really efficient pollinators. They’re very important. And in fact they are not just pollinators, but the larval form when they’re little babies, they actually, a lot of them will eat aphids and they’ll eat other pests too, that at least what gardeners think of as pests.

[00:19:21] So they play a super important role in the ecosystem. And it’s not just that they eat the the aphids or thrips or other things. But some hoverflies actually aid in composting and decomposition and other things. In fact, a lot of sewage treatment plants use hoverfly larvae to help with the breakdown of sewage.

[00:19:43] Yeah, there are certain species that that’s that’s what they do. So yeah, I find them fascinating because I missed them my whole life, you know, until I don’t know, four or five years ago. And I finally started paying attention and looking closely. Most of these flies, they’re pretty small. You know, if you take your average European honeybee, they’re going to be maybe one third to one fifth the size of that or smaller in some cases.

[00:20:08] But the really cool thing is you can identify to species most of the hoverflies because they all have a unique pattern, even though they kind of mimic wasps and bees, they’ll be like this intricate little calligraphy on their abdomen. And that pattern can help you identify them. And I said I would tell you about a specific hoverfly that I, you know, like more than others.

[00:20:30] And there’s a genus that are actually called calligraphers.

[00:20:33] And it’s like some little artist was drawing this special calligraphy

[00:20:38] on the back. So, yeah.

[00:20:40] Michelle Fullner: And they’re yellow and black?

[00:20:41] Michael Hawk: Yellow and black,

[00:20:42] yeah. 

[00:20:43] Griff Griffith: I have some that are, if they’re yellow and black, I haven’t seen it yet. Like they’re really, really small and it’s often gray here. Cause I’m right on the coast, but that’s the main insect I see flying around are fringe cups, one of our native plants here, and I always tell people like, bees are cool because they pollinate bees.

[00:21:00] But hoverflies can pollinate and they’re predators. You know, they’re like twice as cool.

[00:21:06] Michelle Fullner: Pull in double duty.

[00:21:07] Michael Hawk: I mean, there are some that are not yellow and black. I’m thinking of one called a grass skimmer that’s black and red. You know, and, and sometimes they have this really shiny gold on this special part on their, on their back. , I have a photo I’ll have to include it in the show notes, maybe that I call it a self portrait.

[00:21:22] So even though it’s this tiny little hover fly, I had my macro lens and I got really close to it and you can actually see the reflection of me in this shiny gold part of the

[00:21:32] Griff Griffith: Ooh, cool. 

[00:21:33] Michelle Fullner: Oh, that’s a really great shot. That’s cool.

[00:21:35] Michael Hawk: So how can you help? How can you help these wonderful

[00:21:38] Michelle Fullner: Just leave untreated sewage 

[00:21:41] Michael Hawk: Yes, 

[00:21:41] that’s, that’s what I was going to say.

[00:21:43] It’ll save you on your water bill. But maybe something more practical than that is just, I, I like to say leave those aphids alone. So, aphids are, are also super cool, but a lot of gardeners when they see aphids at the first sight of an aphid, they will get out the pesticide or spray them off with water or whatever.

[00:22:00] But what I’ve found personally is It’s so much fun to leave them because usually, not all the time, but usually the aphids will get taken care of by other predators like hoverfly larva or lady beetles or some of the other ones that take care of it. So, 

[00:22:13] Griff Griffith: Inspires a song like, Hey, gardeners leave those if it’s a long Um, uh, 

[00:22:20] Michelle Fullner: Also way better than the raw sewage idea. So I’ll grant you 

[00:22:23] Michael Hawk: Yeah. And, and just to give a little more context, I mentioned some other garden pests, but the, you know, they’ll eat mealy bugs and scale insects and things like that that a lot of gardeners just like. Cringe when they hear so yeah, those natural services from the hoverflies,

[00:22:37] Michelle Fullner: All right. I love it. I love it. Okay. So next one. Is back to me. And this is number seven. And this is one of the most deadly animals in the world. This is my number seven. And I actually had one of these when I was a kid. My brother and I caught it and we kept it outside of our, our home until physics did it in.

[00:22:58] And so this animal’s name was Newton and it’s another California endemic. And this is an animal with an incredible sense of direction. And it can, if you, if you drop it just about anywhere, it’ll know exactly which direction it needs to go to reproduce, right? To find its natal waters, because they always go back to the same places to reproduce.

[00:23:19] And also, it’s a creature that lives a double life. So if you think about the word amphibian, ampha means double and bios means life. So amphibians lead a double life. And this animal is the California newt. And it is found in California only exclusively. There are a couple of other species that are really closely related.

[00:23:38] There’s like a rough skinned newt that looks super similar to California newts. There’s like

[00:23:43] Michael Hawk: that’s what we have in our area.

[00:23:44] Michelle Fullner: Yeah. You have those guys. So we had California newts growing up and I love and adore them. I had no idea how toxic they were when I was a kid, but their skin is, yeah, is like imbued with, it’s tetrodotoxin and it can kill you super quickly.

[00:24:00] So there’s this, This story, I don’t know if this is a true story, if this is an urban legend about these two guys that had gone out camping and one of them went out to the stream, scooped up some water, made some coffee, drank the coffee and, and died. they were trying to figure out what happened to this guy.

[00:24:17] Well, at the end, at the bottom of that pot of water, they found a dead California newt. And so they had cooked this newt and ingested the tetrodotoxin from the newt skin and it killed the guy, which. To me is the perfect alibi, right? You’re like, Oh, my friend scooped up the water. Like, I think it

[00:24:32] Griff Griffith: Oh yeah. Good idea. 

[00:24:35] Michelle Fullner: For sure. It seems extremely shady to me, but that is the legend and it would kill you. Like there’s definitely enough toxin in one of these newts to kill a full grown human being. So. I’ve touched them many, many times. Turns out that’s not actually great like for the newt because we can spread all kinds of little terrible things with our skin and they have super thin breathable, breathable skin as amphibians and so it’s not great for us to touch them.

[00:24:59] I actually now carry nitrile gloves everywhere I go just in case I find a newt and I want to pick it up. So that’s my kind of nerdy thing that I have with me at all times.

[00:25:07] Griff Griffith: And that’s another example of

[00:25:09] Michelle Fullner: Oh yeah, they’re another, yeah, aposemitism.

[00:25:12] Griff Griffith: Mm-Hmm

[00:25:13] Michelle Fullner: California News, thank you, I didn’t get in the description. So they’re like sort of brown on top, sort of a warm brown, and they have these bright orange bellies. Super bright. And they

[00:25:22] Griff Griffith: And I accidentally picked one, one time walking down a trail and I saw it tumble. And when it landed, it landed on all fours, but it arched its backup to make sure I saw all of its orange.

[00:25:32] Michelle Fullner: I did that behavior for you. I forget what that’s called. There’s a name for that behavior.

[00:25:36] Griff Griffith: It’s called You Better Nut.

[00:25:37] Michelle Fullner: Yeah, you

[00:25:39] know, 

[00:25:39] Griff Griffith: It’s

[00:25:39] called. 

[00:25:40] Michelle Fullner: It’s like all the stay, stay back ism. So another little fun fact about these guys, is that you know they, they have some interesting behaviors when it comes to reproduction. They do something called a mating ball.

[00:25:50] And so there’ll be like a female and like four males or more, just all trying to get in there and make the magic happen. So that is called a mating ball and I’ve seen it happen in ponds and things where there’s like just this, it’s a newt ball and you see a ball of newts and it’s like writhing around in the water and that’s what’s going on there.

[00:26:07] So if you ever see that, it’s called a newt ball.

[00:26:09] Griff Griffith: don’t break it up. Don’t be like relax,

[00:26:11] Michelle Fullner: Don’t break up the party. No, they’re, they’re doing fine in there, hopefully, but it’s not our business if they’re not. And then the way to help these creatures, because like I said earlier, they have an incredible sense of direction. And these are animals that can live like 20 years.

[00:26:25] Nobody thinks that newts live that long because they’re just small and you don’t think about that, but they live forever. And they have this amazing sense of direction and they just take their same routes that they’ve always taken. back to where they want to reproduce. But a lot of times humans have put roads in the way of where they want to go.

[00:26:41] And so newts will just plod across roads. They don’t stop and check for traffic. They just walk right across. And so there’s actually groups of people that are like newt brigades that will go out and they’ll actually pick up the newts from one side of the road and ferry them across in the same direction they’re going.

[00:26:56] Love them, right? So if you want to help newts, check in your area to see if there’s a newt brigade. Because there are, so there’s some in like Sonoma County. I know there’s different ones around the state. So check around and see if there’s a new brigade, because there’s probably a lot of different new species that need that kind of help too.

[00:27:11] Michael Hawk: Yeah, my friend Merav leads up this group called Newt Patrol over by Lexington Reservoir here in the Bay Area and it was an overlooked roadkill hotspot until they started documenting this on iNaturalist, by the way,

[00:27:25] and, As a result now several of the agencies that are responsible for the neighboring lands are actually working to create safe crossings for newts, which is a huge win.

[00:27:33] It’s not done yet, but it’s on the right path.

[00:27:36] Michelle Fullner: I love that.

[00:27:37] Michael Hawk: I have a question for you, though. You said that your newt was named Newton and it was done in by physics. So was it like an apple fell on its head or what

[00:27:46] Michelle Fullner: So kinda, I mean, so what happened 

[00:27:48] Michael Hawk: didn’t know if that was a pun or, you know, I’m thinking of

[00:27:50] Michelle Fullner: it was it, so we named it Newton. Unironically, like we just named it Newton because it was a newt and we didn’t know how to take care of a newt. So we just kept it in a five gallon bucket with water. And we had like a stack of rocks in there so that if Newton wanted to climb out and get on the rock, he or she could.

[00:28:08] And one day the, one of the rocks fell and pinned Newton down. Yeah. And so Newton died. Yeah, underwater. It was, it was bad. I was like seven or eight, you know. I was not taking good care of it. It was sad. It was really sad. Poor Newton. Yeah.

[00:28:23] Griff Griffith: It’s funny how all the naturalists brought home little animals to die when they were in their childhood. You know what I mean? I did, too. Things came to my house and died. It was awful. I feel so

[00:28:32] Michelle Fullner: There’s some fatalities.

[00:28:33] Griff Griffith: I’ve made my Are you going to talk about the way that they got so poisonous?

[00:28:38] Michelle Fullner: Oh, is this the, is this the garter snake arms race?

[00:28:41] Is that what you’re talking about? Okay. So I hadn’t, I

[00:28:44] Griff Griffith: I mean, it might be too long, but I mean, it’s so interesting.

[00:28:47] Michelle Fullner: talk about it. You talk about it. ’cause I only know, I have a guess about what’s going on there, but I think that It’s, it’s an example of one of the arms races that I’ve, I’ve learned. And I love researchers who dig up these stories because they are the most fascinating. So whoever dug up this one, thank you. Thank you. Thank you. I don’t know who they are, but apparently the last time I read about it, it started in the Bay area and the, I think it’s the terrestrial or now the aquatic, one of the, one of the garter snakes eats the rough skin new or, you know, that group of newts.

[00:29:14] Griff Griffith: And so. As the newt, you know, became more and more poisonous with this tetrodotoxin, which is the same toxin as in pufferfish. And then the garter snake would get more and more resistant. And so the, and so over evolutionary time, then the new got more and more and more toxic, but the garter snake got more and more and more resistant.

[00:29:33] And so what’s happened is. In some places, the farther away from you get, you get away from the Bay Area. Sometimes the less toxic the rough skin newts get. And I found out this whole thing because I thought they were poisonous. I heard the coffee story years and years ago. And then I saw with my own eyes, a black crown knot heron eat a rough skin newt.

[00:29:53] And I was like, it’s going to die. Let’s watch. And I sat there for hours and it never died. And so I found out that there is a geography to this toxin 

[00:30:01] and this , yeah, it’s super interesting. And then the snakes that are the most resistant allegedly, and I read this once or twice, we might need to double check with another who’s that snake person you just interviewed, Michael?

[00:30:13] Michael Hawk: Oh Emily Taylor, Snakey

[00:30:14] Griff Griffith: Taylor. I mean, we didn’t ask Emily Taylor, but it’s like the garter snake keeps getting more and more bright. The more resistant it is against the talk, it’s bright. So I’ve seen some that look like slithering jewels. And I’ve been like, you are the selected, the special, the

[00:30:29] Michelle Fullner: well, do they become toxic too? Oh,

[00:30:33] Griff Griffith: hypothesis.

[00:30:34] So I don’t know if that’s been studied. I read about this years ago. Maybe there’s more on it now.

[00:30:38] Michelle Fullner: that’s amazing. I didn’t know that. Okay, cool. All right. Let’s jump to Griff. Let’s go back to you because now it’s number six. It’s your turn.

[00:30:45] Griff Griffith: Okay. So. I was a Ranger Rick kid, and whenever I saw something really cool in Ranger Rick, I had to have it or I had to go find it. So there was a article on box turtles. So my mom said, if I save 10 that I could go to and buy a box turtle to pet store. So I like did little work around the, you know, neighborhood, rake leaves or whatever, got my 10 bucks, went and bought my Myrtle the turtle and Myrtle the turtle became My best friend for a very long time.

[00:31:10] It was a Eastern box turtle. So there’s four species in North America, but the common box turtle has like four subspecies and I think Eastern box rules, one of them, if I’m remembering correctly. So I brought her home. She was the coolest box turtle. And I just let her hang out in the backyard and I would catch her eating all sorts of things.

[00:31:28] One time I caught her with a mouse leg in her mouth.

[00:31:32] Seriously. That was the cool. I was like. Nine or 10 at the time, I thought that was the coolest thing ever. So I so we moved a lot, but whenever we moved into a yard, there would be turtle habitat immediately built, which usually consisted of like a water source and some rocks, places for the hide and stuff.

[00:31:47] Everything I read about in Ranger Rick. But then as I got older I wanted a real pond and more turtles and more stuff. So I told all the kids in my neighborhood, if they helped me dig it in the small backyard, that they got to name something that went back there. And so next thing, you know, I had a waterfall and piles of rocks, great turtle habitat.

[00:32:01] And so people would donate. Turtles to me, box turtles. And and then I even stole one, one time from these people in my church. Sorry, Walls. Yeah. I’m the one that stole Quirky. I’m admitting it now, 40 years later, or 40 some years later, Quirky was kept in a box in a room. And. Her scales were coming off and her, her shell was malformed. And so I stole her and and I took her home and her shell hardened up after a year or two. And then she had babies with tank and another turtle that got donated to me. Cause I was like the box turtle rehab place now. So it was, I loved those turtles. They were so cool. They’re not native to California. They’re native to mostly the East coast, you know, depending on what species. And. When I went back East and saw them, the wild, I couldn’t believe that these were wild animals because to me, they were always 

[00:32:51] Michelle Fullner: mm-Hmm. 

[00:32:51] Griff Griffith: then they faced a lot of the same problems that the newts do. They’re being taken in the pet trade.

[00:32:56] And I know that’s a problem cause I used to take rough skin newts home all the time when I was a kid. And so they’re being taken. And the thing about it is, is they want to go home so bad. They have another homing. So they’re looking for their home. So if you take them far States away, when they get out, they’re going to be looking to go home.

[00:33:11] It’s just awful thing to do to anything, to take it away from its home. So the other thing that’s really happening to box turtles is the roadways. So same thing with the new, it’s, it’s the roadways that are killing them. And in some places where their numbers are starting to come back after the pet trade, they’re now being smashed on the roads.

[00:33:28] And so roadways are really something that we have to address. And Ben Goldfarb’s book Crossing has a whole section on roads, which is super amazing, hardcore and really open. Look, there it is. Oh,

[00:33:39] Michelle Fullner: I have it. . I just produced 

[00:33:41] Griff Griffith: cop. So that’s box turtles. I love them. Please don’t get them as pets.

[00:33:46] If you want a pet turtle in California or anywhere, go find an invasive species in your local lake or stream or, and take it home and make sure it can’t escape.

[00:33:55] Michelle Fullner: I just found one the other day. It was massive. It was a red ear. Red. Red. What’s it called? Readier slider

[00:34:00] Griff Griffith: Yeah. I think I’m, I’m getting, I have to go capture, capture some out of my local Creek and bring them home and make them pets. Because that’s what they were to begin with. They’re pets that people let go. Like around here, a lot of the bullfrogs and the turtles that are invasive are released pets.

[00:34:13] But anyways, box turtles. I love them. Leave them where they’re at. And please drive slow during the spring and fall. Cause during the winter, they’re hibernating. And during the hottest part of the summer, they’re like, kind of like estivating or summer hibernating. So it’s the spring and fall. You got to be careful on the road.

[00:34:27] Michelle Fullner: Okay. Great. All right. Let’s jump to Michael.

[00:34:30] Michael Hawk: Well, I’m going to have to change things up again a little bit because we’ve only been talking about animals so

[00:34:34] Michelle Fullner: Oh, okay.

[00:34:36] Michael Hawk: So I’m going to go in a different direction. And this this organism I saw for the first time in real life just a couple years ago. And this was after seeing these beautiful pictures of this weird looking bright red plant that peaks its way out of snow drifts.

[00:34:52] And yeah, you know what it is because it’s a snow plant. And if you’ve ever seen a picture of this, you can’t forget it really because it’s blood red. And it does grow where there’s still snow on the ground. And, you know, so how is this possible? What is this thing that can grow when there’s snow on the ground?

[00:35:10] Well, what it is, is it’s actually a parasitic plant. And the reason that it’s able to grow so early in the season is because it’s tapping in to a nutrient system underground that other plants have developed. In fact, it’s not just other plants, but the mycorrhizal fungi that connect those plants together.

[00:35:28] So this, this plant, it’s bright red because A, it doesn’t photosynthesize. It doesn’t need to because B, it’s a parasite. Um,

[00:35:39] Michelle Fullner: It was like, it’s not easy being green. I’m gonna be red.

[00:35:42] Michael Hawk: yeah,

[00:35:42] Griff Griffith: Right. And it actually flowers too! There are so many parasitic plants that I think get overlooked, but 

[00:35:55] Michael Hawk: pollen. , so they’re very cool from that standpoint. So the way it works, I just want to elaborate a little bit because As a parasite, I think a lot of us, when they hear that word, you kind of get this negative connotation.

[00:36:12] You think of things like ticks or fleas or roundworm or, you know, things like that, that we don’t like. But I would challenge people to maybe try to grow a different perspective on what it means to be a parasite. And it’s just a different lifestyle that has evolved or has occurred depending on how you look at the world it’s you know, or created, you know for that matter and if you were to adopt the perspective of the parasite And think about what would they think of us, you know, we we look at them and they’re like, oh, they’re freeloaders They’re you know, they’re you know doing these things without the work You know, they may look at us and be like you all are so frantic and wasteful You Yet, you know, we’ve learned to live a life that values patience and efficiency and you know The art of doing more with less so these plants do more with less by tapping into the mycorrhizal fungi that are there trading nutrients providing nutrients for the plants in the community that they’re that they’re in and they’ve developed this kind of Relationship with this other relationship.

[00:37:15] So it just shows me like all of this You Interconnectedness. I’m struggling to find the right word here because it just blows my mind every time because you have, you have the, the fungi that are connecting the plants together and helping get nutrients to the plants. And then you have this parasitic plant that’s coming in and tapping into that and providing its own services and its own beauty you know, out to the world.

[00:37:35] Griff Griffith: Have you guys ever seen a parasitic plant in anybody’s native plant garden?

[00:37:38] Michelle Fullner: Oh, no.

[00:37:39] Michael Hawk: That would be really hard. 

[00:37:41] Michelle Fullner: That would be hard. That would be like a multi year project, probably,

[00:37:45] Griff Griffith: Higher level

[00:37:46] Michelle Fullner: a really cool, 

[00:37:48] you’d have to get these really great mycorrhizal networks going on first for, for the micro heterotrophs, especially.

[00:37:53] Griff Griffith: not if you use dodder. Maybe if you use the that orange string looking plant that is that, that bites into things like a vampire, that’d be kind of cool plant to add to your native plant garden.

[00:38:02] Michelle Fullner: Yeah. Fathers be good to your daughters, as John Mayer would say.

[00:38:07] Michael Hawk: I, I’m so tempted to go off on data right now to be his dodder. So amazing. It’s recently been shown that it can kind of like see in a way when it first sprouts, it just has a day or two to find a host

[00:38:19] and 

[00:38:20] somehow I can 

[00:38:20] Griff Griffith: lapse videos of it. 

[00:38:22] Michael Hawk: Yes, it can evaluate what’s nearby and what the best choice is for it to go grow towards.

[00:38:27] And there’s so many amazing, you know, parasitic plants. Like mistletoe is, is a hemiparasitic plant. It’s

[00:38:32] partly it does photosynthesize, but it’s important for wax wings and bluebirds and so many other species

[00:38:39] Griff Griffith: And the kites nest in it.

[00:38:40] Michael Hawk: yeah, yeah. So anyway, that’s how to help, you know, don’t just assume that if something is parasitic, that it’s harmful or negative for the environment.

[00:38:49]  They’re part of the food web. They’re part of the ecosystem and. provide many other services to many other plants, animals, and insects.

[00:38:57] Griff Griffith: If you have an awesome parasitic plant growing in your native plant garden, it’s obvious that it’s in our garden, send it to us and we will post it on our Facebook pages

[00:39:05] Michelle Fullner: Yeah, that’s

[00:39:06] Griff Griffith: and give you a shout out.

[00:39:07] Michelle Fullner: That’s so cool. Well, and actually, also, it’s really funny that you chose that plant because just literally two or three days ago, I posted in my Instagram story, because I want to make a video about these, this family of plants. It’s called mycoheterotrophs, or maybe not family. I don’t know how related they are to each other, but mycoheterotrophs.

[00:39:23] So, so myco being mushrooms or the mycorrhizal networks, right? That are, we think of as mushrooms, although those are just the fruiting bodies. And then heterotroph, meaning that they have to eat other things, right? Like, autotrophs feed themselves, heterotrophs eat other things. We’re heterotrophs, sometimes I resent that because I want to just lay in the sun and like, then just have energy.

[00:39:43] And that’s not the way it works, but But anyways, , these cool plants that are plants and not fungi, even though they look like fungi a lot of times, because they have these weird colors and they pop out of the ground in these weird ways. I don’t have any pictures of them. So I’m actually crowdsourcing a reel right now because I want to make a video about them because I think they’re super interesting.

[00:40:00] And so I Instagram story, I’m like, Hey, plant nerds, like if anyone has any mycoheterotrophic photos, 

[00:40:05] send them 

[00:40:05] Griff Griffith: took a picture of one last week. I’ll send it to you.

[00:40:09] It was, it was interesting. Cause the Forester from Redwood Rising, Lathrop Leonard was like, Oh, and sometimes there’s ghost pipes and coral root up here, keep your eyes open. And I was like, there it is. And it was one just coming out of the ground.

[00:40:20] It’s all like pink, red, and it’s like just barely coming out of the ground, so I’ll send that one to you.

[00:40:25] Michelle Fullner: Sweet, cause most people sent snow plants, cause that’s what I talked about. But some people sent like some ghost pipes that were very cool 

[00:40:32] Michael Hawk: I have a few I could send you.

[00:40:33] Michelle Fullner: Ah, that’d be rad, thank you. Okay, who are we on? Is it my turn again? It’s my turn again,

[00:40:37] so number four. Also, not an animal. Not as mysterious or unknown as Michael’s not animal. But this one is a keystone species. So, it is not a parasite. Although I am acknowledging that parasites can be extremely ecologically beneficial.

[00:40:55] Lots of, lots of good that they’re doing in the world. But this one is actually a host species for just a myriad, a myriad of other species. And it plays a really crucial role. role where it is native. And so in particular, there’s a whole family of these beings, but the one that I particularly love is the Valley Oak. So I adore these plants. They are like, they can grow to be like a hundred feet tall. I think there are most majestic Oaks. They’re the biggest Oaks in California, maybe the biggest Oaks period. I’m not sure about that. They’re definitely the biggest Oaks in California, the tallest. And in some cases they can live like 600 years.

[00:41:32] So, these are ancient, majestic, like, wonderful trees. And they’re not as old as, you know, the redwoods or the sequoias, but they’re, they’re very old. And then there is that one community. It’s not valley oaks. But there’s some kind of like oak situation, Michael, or maybe Griff, maybe you guys know about this.

[00:41:48] What’s that ancient oak that is like re sprouting from the roots, I want to say? It’s not like a single stem that’s super old, but it’s thought to be like the oldest organism. It’s not a bristlecone pine. Like, it’s an oak. You guys know what I’m talking about? I’m 

[00:42:00] Michael Hawk: No. 

[00:42:01] Griff Griffith: California? Is it in Southern

[00:42:02] Michelle Fullner: I want to say it’s Central Coast somewhere, but

[00:42:04] Griff Griffith: I do remember reading about

[00:42:05] something that’s copper themed. Yeah, 

[00:42:07] it’s, it’s, it’s. It’s coppicing over and over

[00:42:09] Michelle Fullner: Yeah. Yeah. Yeah. Anyways. Okay. That’s an oak. This is a different oak, but valley oaks are the ones with the alligator skin bark. They’ve got very like furrowed bark, really rough looking. They’ve got the gnarly long limbs. And sometimes when they start to get older, they’ll send them down to like the ground and like have, you can just walk up a limb.

[00:42:27] They’re really beautiful. They have the really lobed leaves. And I think that they’re really mysterious and gorgeous and majestic trees. But in addition to that, they’re hosting hundreds of species of insects, which is super important because we’re having large insect die offs globally. We’re having a lot of problems with insect populations, not universally.

[00:42:47] Some insects are faring okay, but they’re not always the ones that we want to be faring okay. So oaks are really great because they bring in that Biodiversity, because they support so many different species of insects, and then there’s a lot of birds and things that use those to raise their young. So birds need tons of caterpillars to raise their baby birdies, and so they get those from the oak trees a lot of times, so.

[00:43:08] You get actually more bird diversity if you have the same kind of density of canopy. in an area. This was a study done in Sacramento, actually. You can have the same density of canopy in urban trees, and if there are oaks present, there are like seven more species of birds present. So regardless of like, how much tree cover there is, it’s the presence of oaks that’s making the difference.

[00:43:29] Griff Griffith: And if you live in an area that’s, that has set an oak death and it’s killing oaks, you can plant valley oaks because they don’t get set an oak death.

[00:43:37] Michelle Fullner: That is a great point. Yes, but one thing that they do have a problem with is the Mediterranean oak borer beetles. And so those were found in St. Helena in like 2017, something like that, and they’ve been spreading. So it’s a beetle species, yeah, where they’re, they’re boring and they kill the oaks. And that’s a really huge problem because the oaks are, you know, these food sources 

[00:43:59] Griff Griffith: keystone species.

[00:44:00] Michelle Fullner: Yeah, Keystone species. So, so anyways, it’s a huge problem. There’s also other species of beetles that affect other oaks, like the gold spotted oak borer. That’s more in SoCal, I think. That’s in the Black Oaks, the Coast Live Oaks, and the Canyon Live Oaks. But in the Valley Oaks, they’ve started to see these Mediterranean oak borer beetles.

[00:44:20] And one of the ways to help trees is to In general, specifically the valley oaks, because I love them with all my heart. They’re probably my favorite species, period, is to not move firewood around. Like if you were going camping, buy your firewood right there where you’re going camping. Don’t bring your firewood with you because these little beetles hitchhike on the logs and then they get into a new area.

[00:44:39] They escape from the logs. They don’t get burned up in the fire. Maybe some of them do, but some of them escape into the neighboring trees and they can cause massive infestations. So especially if a forest is stressed at all. It’s going to be extra susceptible, but also if it’s just this non native species that maybe the tree doesn’t have a natural defense to, I’m making that part up, but I’m guessing that that would also make it more susceptible.

[00:44:59] So those are, that’s one key thing that you can do that helps a lot of different tree species, not just oaks, not just valley oaks, is just don’t move firewood.

[00:45:06] Michael Hawk: What about the woodpecker brigade? An army of woodpeckers just everywhere, you know?

[00:45:11] Michelle Fullner: Bring them in.

[00:45:12] Griff Griffith: Bring them in.

[00:45:13] Michelle Fullner: I like it. So that was number four. We got Griff with number three.

[00:45:16] Griff Griffith: Number three. So of all animals, of all animals in California or animals period that I’ve had a relationship with it’s, it’s a genus, it’s the salmon Actually, it’s the coho salmon the most. So I grew up fishing for salmon with my grandfather, and then I started doing salmon habitat restoration when I was 18 in the California conservation core.

[00:45:37] And then went on to the forest service where I did fishery surveys, mostly for salmon, but all fish, but mostly it got to be mostly salmon. Cause those are the ones that were like the most in politics and. Important to indigenous folks, because a lot of the indigenous folks in my area, Wiyot and the Talawa and more Hoopa consider themselves like acorn salmon people.

[00:45:57] So salmon was like central to their culture. It’s a cultural keystone species for a lot of people. And which is cool is I’m Irish. And we also called ourselves in Southern Ireland acorn salmon people, because we were also eating acorn and salmon. 

[00:46:11] So my relationship hasn’t just been, you know, doing biological surveys on them and doing restoration. Also, I wanted to be a commercial fisherman for salmon because so many men in my family had done that. And it was important to me in my twenties to continue that. For some reason. So I went up to Alaska and I worked on a fishing boat and caught tons and tons of salmon and.

[00:46:32] I really understand the relationship between them as not just an important ecological species, an important cultural keystone species economic species. It’s, they’re really part of our identity in California, the Salmon are, and, and have been for thousands and thousands and thousands and thousands and thousands and thousands of years since time immemorial.

[00:46:52] And we’ve had. Commercial fishery shutdowns here in California. And I think that that really speaks to how we’re doing stewarding. Like salmon are a good indicator of how we are doing as stewards. And the fact that we’re losing them is not a good sign. And so many people are trying to bring them back.

[00:47:10] So many folks are working on bringing the salmon back and there’s lots of ways you can do that. So we won’t get into all of them, but salmon have a lot of interesting. Like so many interesting stories. And I would highly recommend looking up the indigenous people’s stories about salmon and the communication networks they had about salmon.

[00:47:27] Like there would be several tribes along a river and they would wait till a shaman or elder at the most up river. The most uprooted destination of the salmon would, it would give a blessing. And then that’s how the tribes down river, they would all agree to then start fishing. And these were people of different languages and religions and different cultures.

[00:47:47] This wasn’t like, this wasn’t like a monolith or monoculture. All these people were different and they cooperated. Around the salmon. So there’s a lot of stories like that with salmon. And I think that the day that we bring back salmon and salmon are off the list and we have a salmon fisheries reestablished, and we have trees that are getting marine nutrients from the wildlife dragging these salmon carcasses.

[00:48:09] Cause salmon die after they spawn, you know what I mean? Life is a virgin and then you die. That’s, that’s what I think about with salmon. Like they, it’s, you know, they meet the love of their life, if you will. And then they die shortly after. But their bodies would get drug into the forest. And so we still see these marine markers from salmon up in these trees that are far away from the water.

[00:48:28] And that’s because there used to be so many salmon. It’s hard to even imagine how many salmon there used to be to anybody who’s been born after, you know, 1950. We can’t even, we can’t even fathom how many there were. And. Back in the day, people say there’s so many, you can walk across their backs. There was so many, you could dance across, you could break dance across her back.

[00:48:45] There was tons and tons. I’ve seen it in Alaska, the way it used to look down here. And I hope one day that we can bring that back. So one thing people can do right now is it’s going to sound counterintuitive, but it’s not buying farm raised salmon, making sure your salmon are wild caught. Not eating salmon right now.

[00:49:01] I mean, even at the Yurok Salmon Festival, this is going to be the second year in a row where they haven’t had salmon at the Yurok Salmon Festival. So maybe switching to another fish for a while. Also knowing that everything ends up in the water. So whatever toxins you’re using around your waterway are ending up in there and they’re affecting the fish. So there’s a bunch of little things you can do. There’s a lot of different websites and stuff like that, where you can learn how to help salmon. But coho salmon are different from a lot of the other salmon in California because their babies stay in the creeks all summer long, which is

[00:49:29] unusual. So when you see baby salmon with the black par marks, those like vertical marks down their bodies.

[00:49:34] When you see those in the summer, those are probably coho. And that’s why they’re the most endangered is because they’re Left with us during the summer and the droughts and the water diversions, especially all the water diversions has really led to a shortage near extinction, extinction in some watersheds of the coho salmon.

[00:49:50] Michael Hawk: Can you elaborate on that kind of counterintuitive thing that you said about, you know, it’s better to buy wild caught salmon rather than farm raised salmon?

[00:49:59] Griff Griffith: So a lot of the farm raised salmon, and I haven’t followed up on this in the last couple of years. So if someone wants to correct me, I’m way into it, but farm raised salmon. Their meat is dyed, first of all, so it can be pink, but there’s so many of them concentrated in small areas and usually at the mouth of rivers where adults are gathering and waiting for the rains to come so they can make their way up into their natal streams because salmon are anadromous, so they start in the fresh water, they go out to the salt water, live three or four years, and they come back and spawn and then die in the fresh water, which is really.

[00:50:30] Really interesting cycle and the indigenous people have great stories around how to explain that to their kids or to themselves. It’s super interesting, but when you have a gathering. You know, a not unnatural gathering of salmon doing their, almost their whole life cycle in the river. And then you have the native ones, the wild ones going past this.

[00:50:48] They’re catching those diseases, sea lice and those other diseases, and it’s killing them. And so we don’t want to support farm raised salmon. We don’t want farm raised salmon to happen. We want to fix our streams, when to restore our streams, because we don’t need to have pens of salmon. We need to have streams.

[00:51:05] Full of salmon

[00:51:06] Michelle Fullner: hmm. Better Pink from the food that they eat.

[00:51:08] Griff Griffith: that are pink from the food they eat, not from dye.

[00:51:11] Good hmm. So, we had salmon. That was number three. Michael, what you got for us for number two?

[00:51:16] Michael Hawk: For number two, I’m going to tie back into your valley oak story a little bit here. And I I also maybe gave a little bit of a preview as to what this species is. So these are large and gregarious species. Many different kinds across the world I think with the exception of Australia and Antarctica and it’s woodpeckers. woodpeckers are very often as, as kids, one of the first birds that we notice because they are maybe colorful and gregarious and maybe they were even pounding away on the side of your house at some point and you’re like, what’s going on out there? In particular, I want to talk about the acorn woodpecker, which is found in many parts of the Western U.

[00:51:57] S. And I think that the name actually gives a little bit of tip off as to how they relate to Valley Oaks, because as an acorn woodpecker, well, obviously they must like acorns, right? And they do, but like so many common names, there’s another layer to the story. So acorn woodpeckers, they live in these communal groups you know, family groups very often, and they will go out and they collect acorns, and they store them in specially drilled holes that they make, where they just will, will make the hole just big enough and then wedge that acorn in there.

[00:52:31] And you can have thousands of acorns stored together. in a, in holes on a tree or on a power pole. A wooden power pole is one of our favorite places, actually. And and each of these little holes will have acorns, like every few inches, scattered across. And that’s called a granary. And I’m going to go off on the granaries here for a little, little bit and then come back to why acorns are not where the story ends for these birds.

[00:52:55] But the granaries are really interesting because if you put a fresh acorn in a hole and you put it in there really tight, because you don’t want somebody else to come along and steal your acorn, right? So, so you’re a special bird. You’re this really metal bird that you can bang your head against solid wood at forces that, you know, we can barely even fathom.

[00:53:14] you can really wedge that thing in there, but that fresh acorn is going to dry out at some point, or maybe there’s an insect inside that acorn and it eats it and it shrivels up a little bit and it gets loose. So there are, you know, specific birds in these communal groups that manage the granary and they go around patrolling, looking for loose acorns.

[00:53:33] And they’ll take it out and find a better fitting hole and continually move these acorns around and sometimes discarding the old, you know, the really old ones. Now you might be wondering, well, why are they storing all these acorns and not eating them? You know, why are they, why are they letting them dry out in the first place?

[00:53:50] And that’s because like almost every woodpecker, they prefer insects. So despite their name, Any chance they get, they would rather eat an insect. It doesn’t matter on what time of year it is. If there’s an insect available, they’re going to go for the insect. And in fact, acorn woodpeckers can fly catch. So like there’s this whole category of birds called fly catchers that, you know, maybe if you’re lucky, you get to observe one sometime and it will sit on a perch and it will look for a bug flying by of some sort, and it will sally out and grab that bug in midair and come back and, and eat it.

[00:54:20] Well, acorn woodpeckers will do the same thing if the opportunity arises. So as the day warms up, if you have a chance to look at acorn woodpeckers, you’ll see them fly catching. Now, on top of that, they will also mimic, well, mimic is too strong of a word, but, but they’ll use similar strategies to what a sap sucker will use.

[00:54:38] Whereas, you know, sap sucker is another type of woodpecker will go and drill these little holes and let the sap leak out and then insects get caught in that sap and they’ll come back and, and they’ll eat those insects. Acorn woodpeckers will do the same thing. Sometimes their own. you know, sap.

[00:54:52] Sometimes they’re taking advantage of other sap as well. So it’s really cool. And the acorns are just kind of a backup plan for them. So these are the planners of the woodpecker world where they have this large store of backup food just in case they need it, which by the way, sometimes attract insects too.

[00:55:08] So they can look like they’re eating the acorn, but they’re really going for that insect.

[00:55:12] Griff Griffith: So some people are probably wondering why the acorn whippeckers want their acorns to be so tight in those trees. 

[00:55:19] Michael Hawk: Yeah, 

[00:55:20] Griff Griffith: are they, why don’t they like it? Loose ones.

[00:55:22] Michael Hawk: yeah, like, 

[00:55:23] so when I was talking about other animals stealing the acorns, and that’s why they want it to be so tight, like, I’ve seen this actually happen, in fact, where an acorn woodpecker had some fresh acorns, and it was going to put it in the granary, and it starts to tap it in, and then suddenly like a raven or a crow will come in and scare away the woodpecker, and it’s able to steal that acorn and have it for itself, and squirrels would want to do the same thing. So there are many other animals watching. These acorn woodpeckers, and if those acorn woodpeckers can’t get those acorns tightly fit, it’s an easy meal for some other animal.

[00:55:55] Griff Griffith: Yeah. Speaking of drama, that’s some of the, that’s some of my favorite bird watching is acorn woodpeckers at the granary. That’s some good drama. Cause they’ll chase off anything. They are brave up there. I love it.

[00:56:06] Michael Hawk: they are. So now, how can you help? Well, listen to Michelle and plant some valley oaks. Protect those valley oaks. If you don’t live in California and you don’t have valley oaks, really you know, oak trees are great for all woodpeckers. Thanks. Part of it is because most woodpeckers are cavity nesters.

[00:56:24] They need holes in big, old, mature trees. And oak trees, very often when they get mature, they lose a limb, a hole develops, maybe there’s some carpenter ants that help along or, you know, something like that. Woodpeckers don’t always excavate their own holes. Sometimes they use naturally occurring holes, but other times they will excavate their own.

[00:56:41] So big, old trees, keep those around. Support those insects. Like we’ve talked about in a couple of different ways, because most woodpeckers will eat insects, you know, as their primary source. And the other thing is if you have a big old tree that has cavities in it, don’t just cut it down as long as it’s not a safety concern, you know, if it’s a safety concern, you know, that’s, that’s

[00:57:01] Griff Griffith: Cut it to height, cut it to height. If it’s a 

[00:57:02] Michael Hawk: Cut it to height. Exactly. So if you can leave a good chunk of that trunk, like up to where there are some holes, you’re doing a couple of things. You’re leaving those cavities, but then you’re also supporting the habitat because dead trees, trunks, things like that are habitat for many other organisms, not just birds.

[00:57:22] So, it’s very overlooked. We want clean, pristine parks and lawns, and it’s so tempting just to go remove these things, but lots of cool stuff happens on you know, on these dead and dying trees, if you can keep them.

[00:57:34] Griff Griffith: I just moved into a new place and I’m talking my housemates or whatever they’re called neighbors um, into creating a Snag out of a Bradford pair. And so, cause I’m going to girdle it and then we’re going to cut it to height and then they’re artists types. So I said, it’d be great if you guys could do some art on it and drill some holes in it and some cool patterns for the native bees, and that was the deal.

[00:57:58] That was how I sold it was. Do art on it. So we’re going to have this snag that’s going to have tons of art on it. We won’t get acorn woodpeckers here because it’s too close to the coast, but we will get some coolness and I can’t wait to see it. So if people aren’t into having snags in their yards or standing dead trees, you can cut them to height so they don’t fall on your house or fall on anybody.

[00:58:17] And then you can make art on them. And that might be a way to get standing dead trees more welcomed into our spaces.

[00:58:24] Michelle Fullner: That’s a great idea. 

[00:58:25] I love it. I love it. And speaking people’s language too. I love that you didn’t just be like, you know, you, you specifically knew you were talking to artists. So you’re like, Hey, let’s do art here. So tailoring your message or finding out about people before tailoring your message to them so that, you know, you 

[00:58:40] Griff Griffith: That’s how I got them on board. I was like, what, what patterns we plant these yellow flowering tidy tips in? And they’re like, Oh, we know they didn’t give a crap about gardening before, but once they got to do their expression, all of a sudden they got interested. They painted pots, all kinds of stuff.

[00:58:56] Michelle Fullner: Brilliant. 

[00:58:56] Michael Hawk: That’s awesome. And, you know, connecting in that way is great. I wanted to go back real quick to cavity nesters because cavity nesting birds, like many, many, many birds, most birds are in decline with a few exceptions, but the cavity nesting birds are very often doing worse than than many other birds because We have so few old growth trees and when they do get old and they start to look like they might be a safety risk, they get cut down to the ground, even in parks, you know, because it’s a liability for them.

[00:59:27] So, I, I can’t really stress this enough. It’s one of those, you know, hiding in plain sight conservation issues that we have.

[00:59:33] Michelle Fullner: Also, to me, it’s like whoever goes and takes a picture of just like a very normy looking tree. You know what I mean? It’s like, it’s beautiful when a tree has character. I wanna go and take a picture of a, a crazy like gnarled old tree with holes in it and stuff like, that’s more interesting to look at and has more character.

[00:59:49] And I think that it, it lends some of that to the adjacent kind of surroundings.

[00:59:55] Michael Hawk: And what’s better than getting a picture of a baby bird sticking its little head out of a hole in the side

[01:00:00] Michelle Fullner: That’s the best. That’s the best. Okay. For our number one. We gotta be ready. Let me go grab my hat. Oh, okay. I have this hat, and I have some slips of paper in here. Get some of those noises on the mic. And on the strips of paper, I’ve written different sports. Okay? I don’t know a whole lot about sports.

[01:00:16] And, that’s okay. Good. We’re kind of in good company. But I know the general idea of how these sports are played. And so, there were three of us. We each had three different sports. favorite species. And that means that we had a list of nine, but we need a list of 10. So to figure out whose top pick gets to be number one on the list, we need a way to figure that out.

[01:00:36] So what we’re going to do is I’m going to draw out one of these sports and read what the sport is. And then we’re going to each make a case for which of our species would win against the others. Why would our species be good at that sport? Alright. Does everyone understand the rules? Is that good?

[01:00:51] Griff Griffith: we’re going to reveal the name and then tell why it would be the

[01:00:53] Michelle Fullner: Yes!

[01:00:54] Exactly. Okay. Okay, so, the sport is okay, somebody say when.

[01:00:58] Michael Hawk: Go. 

[01:00:59] Michelle Fullner: Okay, soccer. All right, so who wants to go first? Who’s going to win at soccer?

[01:01:04] Griff Griffith: my species will lose because it’s stuck in the ground,

[01:01:09] but if you, soccer in the ground. I a ball. It’s If you kick a ball at it, it might ricochet back into the goalpost. That’s the only way that we would score.

[01:01:18] Michelle Fullner: What’s your species?

[01:01:19] Griff Griffith: Coast Redwood.

[01:01:20] Michelle Fullner: Of course it is. You’re being on brand today, too. All right, Coast Redwood. I love it. Well, I mean, I think, though, that they’re pretty wide, so they could make a great goalie.

[01:01:30] Griff Griffith: And their roots are really shallow,

[01:01:32] Michelle Fullner: There you go.

[01:01:33] Griff Griffith: so if they got some X Men powers, it would be easy for them to unbury their roots and kick things in, you 

[01:01:37] Michael Hawk: Well, I have a question. How long is this game? If we’re talking about like a multi thousand year game,

[01:01:43] Michelle Fullner: They’re the Redwoods are Oh yeah, that’s true.

[01:01:46] Honestly, change the terms a little bit, right? We got to be on plant time.

[01:01:50] Griff Griffith: It takes 2000 years. Yeah.

[01:01:53] Michelle Fullner: Humans are too hasty.

[01:01:54] Griff Griffith: Okay. Well, in that case, we got it.

[01:01:55] Michelle Fullner: Yeah. Coast Redwood’s great. Awesome. Michael, Unless someone’s got a bristlecone pine.

[01:02:00] Yeah. Outlast everybody. 

[01:02:02] Michael Hawk: species is a bristlecone pine.

[01:02:05] no! no, no, no. So my species, I’ve already talked about a little bit today. It’s aphids. And I think aphids would win this without a doubt because they can reproduce so fast. They’re just going to win in numbers.

[01:02:20] And, you know, the reason they can reproduce so fast is because.

[01:02:24] They give live birth. I don’t want to get into my whole aphid story here, but but yeah, I think I think aphids, they’re super

[01:02:29] Griff Griffith: They’re born pregnant, even.

[01:02:31] Michael Hawk: Yeah. So 

[01:02:32] Michelle Fullner: I’m

[01:02:33] Michael Hawk: they

[01:02:34] Michelle Fullner: sorry. You just blew my mind. I’m sorry. I’ve been pregnant and I was not good at playing soccer when I was pregnant. So I will just go ahead and put that out there. All right. So mine. is the yellow billed magpie, another endemic species. It’s a California endemic bird and it’s got this striking yellow bird.

[01:02:53] It’s a corvid and it’s got this long beautiful tail. It’s got these white wing tips. They’re just very distinctive, very easy, even for somebody like me who doesn’t know anything about birds to identify. I can spot these birds. There’s a certain neighborhood in Sacramento. Every time I go there, I’m like, Oh, there’s a bird!

[01:03:07] I’m in Arden now. There’s yellow billed magpies. Like, they always greet me every single time that I go in there. And I think they would win at soccer because they’re incredibly smart and cooperative. And so they have these like groups, right? Like they are able to communicate with like different squawks and things.

[01:03:23] So they are able to communicate with their groups. They’re cooperative, like the parents raise the babies together. And sometimes even like the older sibling will come and help raise the baby. And they’re corvids. They’re super smart. They’re like one of the smartest birds that’s out there. So I think they would have the strategy down.

[01:03:38] So I think that’s why the yellow billed magpies would win.

[01:03:40] Michael Hawk: The aphids would just fly into their eyes. Reproduction

[01:03:43] rate. I 

[01:03:45] Griff Griffith: would fall and crush everybody.

[01:03:47] Michael Hawk: I but the mags are op, they’ll eat whatever’s available, so they’re just, they’re gonna take out the aphids. So we’re just gonna gobble them up.

[01:03:57] the aphids got it.

[01:03:58] Michelle Fullner: Alright, alright, what do we think? So, out of these three, this is the part that I didn’t actually think through. How do we decide, after we make our case, which one of these actually wins?

[01:04:08] Michael Hawk: I should have picked the dung beetle is,

[01:04:10] Michelle Fullner: Oh, that would have been perfect yeah, 

[01:04:13] You know what though? Maybe the, the Coast Redwood wins for goalie, for sure. And the, you know, the yellow billed magpie is a great, like, coach be able, because it’s going to be able to tell those aphids where to go, and the aphids could be the actual players. Although I don’t know if they could move the ball, so that’s kind of a

[01:04:29] Griff Griffith: Maybe 

[01:04:30] if enough of them got on one side, they could use like gravity.

[01:04:33] Michelle Fullner: All right, so do we have to draw these out of a hat? Like, how do we decide which one is the winner? 

[01:04:38] Michael Hawk: I don’t think the aphids would win if I was being honest. I think, I think probably the magpies would win if you could teach them what to 

[01:04:46] Michelle Fullner: have yellow billed magpies be the winners?

[01:04:50] Griff Griffith: I think so. Yeah.

[01:04:51] Michelle Fullner: All right, yellow billed magpies are the winner, so we’ll put them in our number one spot. And these are really interesting birds. because they’re mostly in the Central Valley of California.

[01:05:01] They’re super bright, like I said before, and so they eat just about everything, which can be good and bad because they can eat rodents, which can have problems with rodenticide ending up in the yellow billed magpies. They eat insects, which can end up having problems with neonicotinoids ending up in the yellow billed magpies. So there’s some issues that they face because of their diverse diet. But one of the other really big issues that they face is West Nile virus. So in the early 2000s, I want to say like 2003, four or five, somewhere in there, West Nile virus hit the scene in California and it massively spread. just decimated the population of yellow billed magpies.

[01:05:38] And that population has never fully recovered. And there’s even kind of a question of, can this species build a resistance even once they survive it? Like, are they even building a resistance to West Nile? Or can they just get reinfected and die because they haven’t totally that? And these are super charismatic birds.

[01:05:56] I love watching them. They are absolutely my favorite bird species. I,

[01:06:00] Griff Griffith: can even learn to talk.

[01:06:01] Michelle Fullner: can they?

[01:06:01] Griff Griffith: Yeah. Now I had a friend who back in the eighties, whose mom brought home a baby that fell out of a nest and they kept it and it could learn how to talk and it could talk on cues. So when you walked in the door, it would say, hello. And when you were getting your key, when his mom was getting the keys ready, it would go goodbye, like I had, like it took cues, but it could speak a lot of

[01:06:21] Michelle Fullner: Oh my gosh. So it would sit there in the soccer game and be like,

[01:06:24] Griff Griffith: Yeah, right.

[01:06:27] Michelle Fullner: right. And , so West Nile is a huge issue. I don’t know how much we can do to help with the West Nile issue. So the thing that I said should help this species is not using neonicotinoids. Which is a whole class of pesticides, which are systemic in plants. So they can be applied to roots or they can be applied to the leaves of plants.

[01:06:45] They’re taken up into all the tissues of the plant. 

[01:06:48] Griff Griffith: Including The nectar.

[01:06:49] Michelle Fullner: Including the nectar. Exactly. And so whatever comes along and feeds on that plant, maybe it’s a bee going to pollinate it. Maybe it’s a caterpillar going to munch on some leaves that gets taken up into that animal and then that gets eaten by a bird.

[01:07:01] Or whatever the case may be, and it can, it can move through these different layers or different levels of the food web. So it can affect a lot of different species. So,

[01:07:12] Michael Hawk: Thanks.

[01:07:12] Michelle Fullner: and they can get washed into watersheds. So like when it rains, they get washed into the water and they can end up in a lot of our waterways too. So yeah, they’re real hard to get rid of. They stick around and they kind of just spread all over the place. So they can be real ugly, real nasty stuff. So any way that you can avoid using them, I know that some of them are going to be banned in California for consumers to purchase at some point, but I’m pretty sure that like farms and stuff can still use them.

[01:07:39] And so if there’s ever anything up for a vote and you want to reach out to your representatives to let them know, like, Hey, vote for this, this bill, try to get them banned. That would be a really great move too. Alright, we got our, we got our list, guys. I’m proud of us. Thank you guys for humoring me and talking about your favorite California species with me. This was a lot of fun.

Doug Tallamy for Jumpstart Nature

[00:00:00] Griff Griffith: It’s Griff, your host of the Jumpstart Nature Podcast. Did you love our Solutionary season one? Yes, you did. So did I. I learned so much from our podcast, and that’s one of the reasons why I love doing this, and you must have learned a lot too, because y’all had us ranking number three

[00:00:20] thank you. Thank you very much. This is a dream come true for us because we are solutionaries who wanna make the world a better place. , we love inspiring positive change for conservation, and we do this by bringing you well-researched subjects with cameos from experts and relevant and fun actions to take. If you listen to our podcast and or visit our website, read our newsletter, we will be able to level you up from feeling like a helpless witness of the biodiversity crisis to becoming an effective part, big or small of nature’s, and our own healing. And season two is gonna perpetuate this solutionary momentum. It’s in the works and we’re still a few weeks away from releasing it. So in the meantime, we thought we could share an episode from Jumpstart Nature’s, other podcast called Nature’s Archive.

[00:01:05] This episode is with Doug Tallamy, who is featured in our Yard of the Future episode. He is also the author of my most frequently recommended book titled Nature’s Best Hope.

[00:01:15] Our podcast, Nature’s Archive, is a different style than Jumpstart Nature. It’s more of a conversational interview performed by Jumpstart Nature’s founder Michael Hawk. Each episode is a deep dive into a specific topic. Michael also seeks to understand how his guest got into their field and finds lessons and inspiration to help listeners take their goals to the next step. This episode with Dr. Tallamy focuses on oak trees, and you don’t have to be Irish like me to appreciate oak trees. All right. Oaks support more bird food, aka insects than any other tree in North America. So planting a single oak tree or a few oak trees in a clump is like planting a whole ecosystem.

[00:01:56] This interview was recorded in July, 2021, but it’s still completely relevant today. Dr. Tallamy talks a bit about Homegrown National Park, an organization that he co-founded, and that was started during the time of this interview.

[00:02:10] We encourage you to check out HomegrownNationalPark.org for tons of resources to help you turn your property into a Homegrown National Park. And please check out other Nature’s Archive episodes as well. We’ve covered everything from wildfire to bird migration to fungi, and much more. Visit Naturesarchive.com to see all the episodes and transcripts. So here we go. Nature’s Archive. Interview with Doug Tallamy.

[00:02:37] Carla: Nature’s Archive Podcast, a Jumpstart Nature Production.

[00:02:44] Michael Hawk: My guest today is Dr. Doug Tallamy. Dr. Tallamy is the TA baker professor of agriculture in the department of entomology and wildlife ecology at the university of Delaware, where he’s authored over 100 research publications and taught insect related courses for over 40 years. Chief among his research goals is to better understand the many ways insects interact with plants and how such interactions determined the diversity of animal communities.

[00:03:09] Among his well-read books is Bringing Nature Home published in 2007. And his 2020 book Nature’s Best Hope, which was in New York times, bestseller that expanded upon the topic of his latest book. The Nature of Oaks released in March of 2021 by timber press. Dr. Tallamy is also the recipient of numerous awards for his conservation and communication outreach. As you can probably tell from the introduction. Doug is widely known as a passionate advocate for treating personal properties as critical habitat.

[00:03:39] Today we discuss his most recent work on this theme, the aforementioned book, the nature of Oaks. It turns out the Oaks, aren’t just a little important, but they stand above others in terms of the number of insects they support. Why is this important

[00:03:52] as you’ll hear the majority of birds require insects to raise their young. And I mentioned birds because they’re very accessible and we see them all the time. But this is just scratching the surface of the food web impacts that Oaks. Have

[00:04:05] and we also got into a few basic ecological concepts in relation to Oaks, including Keystone species, trophic levels, energy transfer, and more. We also consider the role Oaks played back when our forest were much more diverse than they are now.

[00:04:18] Before the American Chestnut was wiped out before a Dutch Elm disease wiped out 75% of the mature Elms in the United States.

[00:04:26] And before the current die-off of Eastern Ash trees. Oak’s also have interesting random cycles of acorn production called masting. Doug reviews, the four fascinating hypothesis as to why Oaks are so important.

[00:04:39] He’s also started a nonprofit called homegrown national park. Homegrown national park helps people understand the critical connection they have with functional food webs and ecosystems.

[00:04:49] There was so much discussed and it was a lot of great fun. So without further delay. Doug Tallamy.

[00:04:54] Okay, Dr. Tamiami, thank you for joining me today.

[00:04:57] Thanks for having me. Pleasure to be here.

[00:04:59] Yeah, I’m super excited about this. I was introduced to your books only this year.

[00:05:04] Somehow I had missed all of your work up until recently and earlier guest of mine, uh, Griff Griffith, told me about Nature’s Best Hope. And, uh, I’ve since also purchased The Nature of Oaks on, uh, audiobook actually, and listened to it, taking lots of notes along the way. Uh, so why don’t we get started with that latest book.

[00:05:25] Given all of your ecological interests and your background, what led you to that topic?

[00:05:31] Doug Tallamy: It’s kind of a long story. You know, I’ve been, I have been concerned about the biodiversity crisis for a long time, and it is very clear to me that our park system is not working. , you know, we’re in the sixth grade extinction.

[00:05:45] If it was working, that wouldn’t be a problem. We wouldn’t have 3 billion fewer birds. We wouldn’t have global insect decline. The UN wouldn’t be saying we’re gonna lose a million species in the next 20 years. The World Wildlife Fund wouldn’t be saying we’ve lost two thirds of, of, uh, the Earth’s wildlife.

[00:06:01] Um, so our parks aren’t, aren’t enough, which means we’re gonna have to do conservation outside of the parks. We’re gonna have to do conservation on private property, public spaces like, like roadsides, all the places that we’re not doing it right now. So how do we do that? That’s what I’ve been focusing on.

[00:06:17] It is a global biodiversity crisis, but it has a grassroots solution. I’m trying to give the individual landowner of any, any nature directions on how to, how to address this, this crisis. So I, I, long time ago wrote, uh, bringing nature home that I, you know, moved on to, uh, nature’s best hope, which is simply saying, you are nature’s best hope.

[00:06:41] We’ve gotta do this together. And then the, the latest book again, is The Nature of Oaks. I wrote that because our re research has shown us that oaks are the best keystone plant, uh, in, in the continental us. And remember, I. Keystone. If you, if you think of the Roman arch, the keystone is the stone in the middle of the arch.

[00:07:03] If you take that stone out, the arch collapses. Well, if you take keystone plants out of our food webs, the food web collapses. And it turns out that that out of our native plants, there’s just 5% that are making most of the food, 14% are making 90% of the food that fuels that food. Web and oaks do that better than any other plant.

[00:07:21] So when you have an oak in your. , it’s not a tree, it’s an entire community of living organisms. And there’s, there’s literally thousands of them, hundreds of species and thousands of individuals on that single tree in your yard. I wrote the book cuz nobody knows that this is a case where knowledge generates interest.

[00:07:40] And I hope that interest generates compassion so that people will interact with the nature on their oaks. But they’re not gonna do that if they don’t know it’s there. Uh, and maybe they’ll plant another oak and . So that’s, you know, we need compassion to solve this problem. And that’s, that’s where we’re headed.

[00:07:58] Michael Hawk: Following through on the book, you outline. Many of the different interactions that oak trees have with the environment and, and, and the environment on the oak trees themselves. Everything from soils and fungi to insects and birds and and so forth. And what I was thinking is, as I was in this case, listening to the book, was there’s this sort of basic, maybe overly generalized concept about, uh, primary producers and the amount of energy they create and how much of that is passed along up to the next trophic level.

[00:08:32] And I think the generalization is like 10% usually. And it got me thinking like, as productive as oaks are, does that mean they’re, they’re sort of punching above their weight class, so to speak? Like they’re doing better than 10%, you know, as compared to other primary. That’s

[00:08:47] Doug Tallamy: a great question. I’ve never gotten that question before.

[00:08:50] The 10% is a general estimate that has been challenged for about 50 years, . Um, it could be somewhere around there, but yeah, I, I would say definitely the oaks are punching above their, their weight class. You know, it’s about how much of the energy from the sun you are willing to share with other organisms.

[00:09:10] Oaks share a lot. People say, why, why do they support so much life? Uh, and that’s, you know, there’s about six hypotheses about why they might be doing that. Um, but there are other plants, even other native plants that share very little, like ferns, for example, ancient, ancient plants. But they, they’re really good at protecting themselves.

[00:09:28] They, they grab that energy and they don’t share it. So, uh, if you’re trying to support a food web in your local ecosystem, you’re not gonna do it with ferns. You are gonna do it with, with oaks. So, yeah, that’s a great question. I think they are passing on a lot more of their energy than, than most other plants.

[00:09:44] Michael Hawk: Can you tell me about a few of the most prominent ways I, I, I know one big area of focus is their larval food plants for, for a great variety of insects.

[00:09:54] Doug Tallamy: Right. And that is, that’s really, uh, one of the primary reasons, uh, I got interested in oaks. It’s not just insects, it turns out it’s caterpillars. Um, caterpillars transfer more energy from plants to other organisms than any other type of plant eater.

[00:10:09] So if you don’t have a lot of caterpillars in your ecosystem, you, you essentially have a failed food web. We’ve done. Actually since the, I guess it was the seventies, Dan Janssen pointed that out, but it’s been ignored. Um, so we’re trying to resurrect that statistics. You need caterpillars around and you know, the, the heavy use of non-native plants, and then they escape and become invasive plants in our ecosystems.

[00:10:32] Those plants make, create very few caterpillars. So they devastate the food web by hitting the most valuable insects that are out there. Why do we need so many caterpillars? Well, let’s just focus on birds. It takes thousands and thousands of caterpillars to make one clutch of breeding bird. You know, we, we got a lot of data for chickadee, but there’s data on a number of other things.

[00:10:50] 6,000 to 9,000 caterpillars to get one clutch of a bird that’s a third of an ounce through to independence, actually just to, to fledging. And then the parents continue to feed them caterpillars another 21 days. So you’re talking about tens of thousands of caterpillars required to make a nest of chickadees.

[00:11:07] Now, Chick and most birds forage very close to the nest about 50 meters from the nest. So if you want these birds breeding in your yard, you gotta have all those caterpillars in your yard. If you don’t landscape with the plants that make those caterpillars, you don’t have breeding birds. And we have looked at the data set from Rosenberg at all.

[00:11:24] That’s the group that said, we’ve lost 3 billion birds in the last 50 years. And we divided the terrestrial birds species into two groups, the groups that require insects at some part of their life history, and the groups that don’t. So things like, uh, doves and fis can actually reproduce on seed. They don’t need insects.

[00:11:42] They didn’t lose any numbers in the last 50 years, but the birds that require insects lost on average 10 million individuals per species. So it doesn’t prove cause and effect, but it certainly is suggested that when you take away the bird food, you take away the birds. Uh, so you know if the, if the homeowner’s trying to help the things they like around ’em, and people love birds, you’ve got to give them bird food.

[00:12:04] What plants do that? . Most plants don’t. Most plants support very few caterpillars. So you’ve gotta pick those keystone plants that are the primary producers. Uh, and again, Oaks nine, nationwide Oaks support more than 950 species of caterpillars. So another good native plant around, around, uh, my house is the tulip tree.

[00:12:23] It only supports 21. You know, there’s a big difference here. So blank choice really matters when you’re trying to build that food.

[00:12:30] Michael Hawk: We, yeah. As a birder, when I’m out and about and where I live, coast live Oak is one of the more common oak species and compared to one of the other common ones, valley Oak Coast Live Oak kind of stands above it in terms of the number of insects that, that you find on.

[00:12:44] And, and thus the number of birds. So as a birder, if I find a, a nice mature coast, live oak, I’m gonna spend a few minutes there scanning it, uh, because you know, there will be

[00:12:53] Doug Tallamy: birds, birders have known forever that you go to the oaks to, to watch migration, cuz that’s where the warblers are gonna be. Mm-hmm.

[00:13:01] Michael Hawk: I actually was lucky enough to have a breeding pair of chestnut back chickadees in my yard and I’m in suburbia. You have to go. Uh, I think the nearest oak tree to my yard is probably about a hundred meters away, if not more. So when you mention these numbers of, of 6,000 plus caterpillars to raise a clutch.

[00:13:23] Yeah. It’s just like where are they getting these? Because this is sort of a desert right here where I live.

[00:13:30] Doug Tallamy: Yeah. What would’ve been interesting to put a camera on that nest and see exactly what they were bringing back, and we know a lot about what caterpillars actually. . We also don’t know a lot about what caterpillar there.

[00:13:42] There’s an estimated 14,000 species of, of Lepidoptera in North America, and we only have the host plant for about 7,000 of ’em. But it’s typically woody plants making them, and again, oaks lead the way. So my guess is they were, they weren’t bothering any place Alison, going straight for that, that oak.

[00:13:59] Yeah. . That could be, yeah.

[00:14:01] Michael Hawk: Yeah, I, that’s a great idea. Dexter, I’ll, uh, you know, I have a trail cam. I could just angle it right on the, uh, it’s a nesting box. The, the cavity nester. Mm-hmm. . Mm-hmm. , you know, getting back to the oak trees themselves. I, I know there’s a lot of interesting statistics about the prevalence of oaks across the United States and across the world.

[00:14:20] Do they all have similar impacts or are there Certainly, like here I mentioned the Coast Live oak seems to kind of stand above the others, right?

[00:14:29] Doug Tallamy: Uh, yeah, I, I get that question a lot. And of course, it hasn’t been measured for most, most species. I just had a student compare 16 species in the east here, um, all in the red oak and, and white oak groups, so no live oaks.

[00:14:42] And within that comparison, they were very, very close. White oaks were number one in terms of insect use, but not by a lot. My gut feeling without having measured it is that, uh, deciduous oaks actually are supporting more than the, uh, the live oaks ones that do not drop their leaves. Those leaves get tough, pretty, pretty early on, and, and that’s a real, uh, inhibition to insect feeding.

[00:15:07] But all the oaks are, are good as far as we can tell. So everybody’s saying, which oak should I plant? I tell them to worry more about getting the oak that is most adapted to, to your soil type, your altitude, your rainfall. And don’t worry about the insects. They will, they will follow that, that oak at this point.

[00:15:25] That’s the best information we have. So when I say oaks are, are the number one keystone plant in this country, that’s at the genus level. We don’t have species level information because host records for the most part, say each oaks , you know, they don’t tell you witch oaks. So our natural history knowledge is not good enough to answer that question very well.

[00:15:47] But the assumption truly is that all oaks are good

[00:15:50] Michael Hawk: at the genus level. Then who’s number two and how big of a gap is there between number one and number two?

[00:15:57] Doug Tallamy: Okay. That depends on where you are. Uh, the farther north you go. You know, when you really get up north, the oaks actually drop out. Then willows take over.

[00:16:05] So it’s a toss up in most places between Salix and Cronus, between willows and native cherries. About who’s number two? Uh, so where I live, Oaks support 557 species of caterpillars. Um, willows and prunes and, and cherries both support 456. So there’s a gap of a hundred or so, but that’s still way up there.

[00:16:27] And then, then you go down to Birch’s and, uh, you know, there are many places in the west where cotton woods are, are way up there. They’re, they’re the only big tree. They’re doing well in the riparian areas and they support a lot of things. So oaks aren’t the only good tree. They’re just the best.

[00:16:43] Michael Hawk: The other thing that this always makes me wonder about is if we could rewind, you know, a hundred years, or, I don’t know, I guess a hundred years sort of works back when the chestnut was still prevalent and before Dutch Elm disease.

[00:16:59] And, you know, in more recent time, the, uh, problems with asht trees, do oaks still stand above, above the rest, even in that era or, um, like I, I just, I, I can’t really picture what the food web would’ve looked like back when we had this additional mixture in our forest. ,

[00:17:16] Doug Tallamy: right. You know, the host records, uh, that we use to make up these lists, many of them are quite old.

[00:17:23] They really do go back to those times more than a hundred, a hundred years old, uh, and un unless there were specialists that went extinct. And for the chestnut there, there were, there are at least seven species of caterpillars that disappeared with the, the chestnut. But seven’s, not very many chestnuts are related tos.

[00:17:41] They’re both in the fig ace E and they support it a lot. There are more records for oaks than for chestnuts. It’s probably not a fair comparison because. people weren’t looking that hard when there were a lot of chestnuts around, but you know, we still have chestnut sprouts all over the place, and, and there are, there are records.

[00:17:58] So, um, the best of our knowledge suggests that oaks were number one, even back then. Now, chestnuts were enormously important. in terms of producing the mast that supported many of the vertebrates, you know, or deer and Turkey and bears. And, and it was a good thing Oaks were around to, uh, produce acorns that kept those things hanging in there when the chestnuts disappeared.

[00:18:20] But it was a huge hit on, on the, the food web, not from the point of view of removing caterpillars, although it did. Uh, but from removing , you know, the, the nuts that those, those vertebrates depended on Elms support a lot as well, but, but not nearly as much. But their loss was, was also a hit. Ashes. There are 95 species that depend on ashes, so we lose the ashes.

[00:18:43] That’s 95 more species. The problem here is the cumulative effect of one after another. Uh, and now we’ve got sudden oak death syndrome. We’ve got oak wilt, we’ve got, uh, bacterial leaf scorch, all hitting oaks in different parts of the country. I don’t, it’s not the type of devastation that we saw with the chestnut light.

[00:19:02] At least not yet. Uh, and I hope it never is because boy, if we lose our oaks too, you know, , that will just. Talk about an ecological disaster. A lot of people say, well, you know, look, they’re getting sick. We’re not gonna plant oaks anymore. I, I say just the opposite plant more than ever because what we need to do is find resistance to these disease.

[00:19:23] And it does. The, the response of the oaks that are out there does suggest that there is resistance out there more than, than we saw with the chestnut blight. There’s even resistance to the emerald ash bore. Uh, there’s some, some resistant trees showing up in, in Michigan, uh, but it’s a very small percentage.

[00:19:39] And if you’ve never plant these things again, you’ve got, we gotta get as many genotypes out there in the, in nature as possible so that we can identify the resistant individuals and those are the ones that are gonna take over and it’s gonna be a whole lot easier if you do it before they all disappear than, uh, try to try to resurrect it like we’re doing with the, the chestnut.

[00:19:59] Michael Hawk: That’s a really interesting perspective because I think a lot of people probably look at the risk side of the equation more from a. Local optimization. Like, uh, I don’t want to plant a tree that’s gonna die. So they choose not to. Whereas the, the risk is probably actually greater to not plant the tree, the risk to the species as a whole.

[00:20:17] I, I, I hadn’t thought of it that way until just now. That’s for sure.

[00:20:21] Doug Tallamy: And you know, that tree’s gonna die. Maybe, maybe it’s gonna die in 50 years, 75 years. You can get a lot of, uh, good use outta that tree ecologically before it gets, it gets sick. So, yeah, we’re, I don’t like that

[00:20:35] Michael Hawk: approach. . Yeah. Yeah. And, and of course with the oaks, that’s, I mean, while there are cha, you know, diseases affecting oaks, it’s, it’s not the same.

[00:20:42] And, and I don’t think that’s even a, a consideration at this point, but what people tend to think about more with oaks is, uh, oh, they get too big, or they’re, they’re messy. We have to get over those considerations. I know you have great ways of framing that topic, uh, so I don’t wanna put words in your mouth.

[00:21:01] Uh, but, but how do you help people? See the bigger picture.

[00:21:04] Doug Tallamy: Well, first of all, we have a number of small oaks, particularly in the West. There are oaks that are ground covers. We need to get these into the, you know, the horticultural traits so the people can actually put them in their, their yards. So, uh, in the nature of oaks, I’ve got a list of small oaks, uh, in different parts of the country.

[00:21:22] So it is not a given that all oaks are going to take over your yard. It’s also not a given that all oaks grow so slowly. I hear people say, oh, I’m gonna, you know, I won’t live long enough to appreciate the oak. And they’re picturing these 400 years old oaks. And if you can only appreciate your oak when it’s 400 years old, you’re right, you’re not gonna live long enough.

[00:21:42] But, you know, I’ve got pictures of oaks that germinated that year, pin oaks that just popped their head above the leaves, and there’s caterpillar standing on the ground eating them. They start to contribute to your food wet immediately. So if I can, if we can. Get away from, or at least minimize people’s opinion of plants as being only decorations and realize that they are essential.

[00:22:06] You know, I talk about the keystone plants in, in this ecological house you’re building as being the two by four that hold up that house. They’re, you know, not optional. You gotta have ’em where the house falls down. You do not build a house out of wallpaper. But that’s the way we’ve been landscaping for a hundred years now.

[00:22:22] It’s gotta look nice. Oaks look nice. I mean, you know, a large oak is a wonderful thing to have, have in your yard. Are they messy? Holy moles. You know, life can be messy sometimes, but dead is not more attractive. We can pave over the the world. We can turn it all into lawn. We can wreck our ecosystems and go down the tubes.

[00:22:42] It’s just, it just doesn’t make a whole lot of sense. And I know where it comes from. It’s innate in us to beat back nature, to make it a safe place. Remember, for a long, long time, it was nature that killed us. The predators were hiding out there. The droughts wrecked our crops, you know, it was tough. And the people that beat back nature the best were the ones that spread their genes.

[00:23:03] Well, we’re beating it back real well now and forgetting that it’s nature that keeps us alive, you know, there’s gotta be a happy balance. Uh, so the messy argument, I understand where it comes from. There are cues for care that you can use in your, your yard that allow you to use a lot of native plants without it being all that messy and showing that you’re still a good citizen.

[00:23:26] You know, you’re, you’re, you’re meeting the neighborhood, uh, requirements for neatness, but it’s still a lot more productive. So we have to hit a happy balance. We are not balanced at this point, you know, we’re going, we’re, we’re headed in that direction. I, I do see good, good movement the last 10 years.

[00:23:42] Michael Hawk: It’s one of my best memories as a child.

[00:23:44] Were discovering acorns in the forest. So, you know, one of the things I think of when there’s a concern about messiness, of, uh, of an oak tree, it’s like, that is such a, a fun eye-opening, engaging experience to, to first look at an acorn and take it apart and see there’s a little hole in it, and wonder why is there this little hole?

[00:24:03] What did, where did that come from? And uh, and yeah, I guess it, it really just depends on how you value nature as a whole. Uh, I love the way you say it’s, you know, plants aren’t just decoration. And I think there’s a responsibility that goes along with plant choice. And yeah, you can have a few decorative plants, but, uh, I, I don’t want to turn my yard into an ecological trap where I’m attracting things and then there’s nothing for them to survive on.

[00:24:31] Doug Tallamy: You mentioned the word responsibility, and that’s such an important word. Every person on the planet requires healthy ecosystems. , not debatable. They all require healthy ecosystems. Why doesn’t everybody have the responsibility of keeping our ecosystems healthy? We’ve divided that up. We’ve got a few specialists, you know, a few ecologists, few conservation biologists.

[00:24:52] They’re supposed to take care of the earth. Everybody else has a green light to destroy it. It makes no sense at at all. Uh, because we depend on it. You know, we’re writing the hand that feeds us. So if you have the audacity to say, I own part of the earth, okay, long way that comes the responsibility of stewarding that part of the earth.

[00:25:11] And that means keeping a healthy food web that supports the other plants and animals that run the ecosystems that support us. Healthy ecosystems are not optional. They are essential. And everybody’s gotta make them. If we have them just in our parks and preserves, it’s not good enough. We gotta have them everywhere.

[00:25:30] So yeah, you’ve got a responsibility. And even if you don’t own part of the earth, you still have that responsibility. So help somebody who does help a park, help a preserve, help a a, a land conservancy. It is your responsibility as a member of this planet to keep it in working order. You know, when I was a child, I had hamsters and I had mice.

[00:25:53] You know, I’m raising things, and you observe how they live in their little cage, they had a little corner of the cage, and that’s where they went to the bathroom. They did not mess their nest. Well, if a mouse can figure it out, you don’t mess your nest. We ought to be able to figure that out. So far we’re, we’re not there.

[00:26:12] We’re messing our nest everywhere as if the nest is so big that it doesn’t matter. It does matter. , I’m sorry, I gotta just start ranting here when .

[00:26:22] Michael Hawk: No, I get it. Uh, and, and I do love the way you, you reframe some of these topics, especially because it seems so obvious the way you state it, and, and that’s a skill you have in your writing as well.

[00:26:33] You know, I mentioned the commentary on the use of non-native plants is decorations, which I, which, which, I just love that statement because it’s like, yeah, it really makes you think about what we’ve been optimizing for. And I’ve also heard you say that, you know, on this topic of responsibility, that doing the right thing isn’t a sacrifice.

[00:26:53] You can actually indulge. And there are so many beautiful, unique native plants, native oaks, that you just don’t see in other people’s yards because everybody, you know, again, I’m generalizing, but you know, so many of the same old roses and the same. Oleanders or, you know, whatever else are, are being grown.

[00:27:12] Uh, so I I, I think there’s, there’s a huge creative possibility here too when we start to actually look at the things that are sort of right outside our back door up in the hills or out on the prairie.

[00:27:23] Doug Tallamy: There definitely is, but keep in mind, most people do not garden at all. They hire somebody. So it’s our traditional horticulture trade, the mob blow and go guys who just put in the same plants everywhere.

[00:27:36] It’s cookie cutter and they do it because they’re hired to do it and they’ve always done it, and those plants are available and nobody’s thinking about ecological function. It’s this juggernaut that’s been going for decades. Uh, it doesn’t mean it has to be that way. The, the fancy gardeners are, are recognizing there’s a lot of possibility with native plants.

[00:27:55] But you know, most people are really busy, you know, doing their lies, but they’re not out gardening. Boy, when I first started this, somebody said, you know, you’re never, this is not gonna take off because it’s way too hard. People aren’t gonna do it. My first, first thing I thought of was, you know, what’s hard is figuring out your cell phone, all the apps and everything else, who can figure that out?

[00:28:16] Everybody apparently can, so it can’t be that that hard. Everybody except me, but I do get it, you know? Do you have to have all the natural history, knowledge and, and be a botanist and everything else to be able to use native plants? No, but most people don’t have that knowledge. For the non-natives too.

[00:28:30] They just hire somebody or they go to the nursery and they say, oh, here’s a pretty plant. I’ll buy it. If the productive plants were equally available in the nurseries, they, you know, they buy those too. It is a growing market right now, and nurseries are recognizing that. Mm-hmm. , they don’t have a a, a contract with Asia.

[00:28:47] It’s gotta be an Asian plant. They’re just selling what people have always bought. So when people start buying natives, they’ll sell them as well.

[00:28:54] Michael Hawk: Well, I guess a great thing that we could all do is when we visit the nursery is ask explicitly, where’s your native plant section? Uh, where do you keep your native plants?

[00:29:02] Doug Tallamy: And when they say, oh, we don’t have that, then you leave say, okay, bye. Don’t buy something else. You know, because you’ve gotta turn the mindset around. I understand that a nursery man does not want to carry plants that nobody’s gonna buy. So you have to convince them that they

[00:29:16] Michael Hawk: will. Mm-hmm. , there’s a branching point here.

[00:29:18] I love to hear more about your broader efforts to help property owners and homeowners. Uh, but I wanted to circle back on a couple more oak topics because you mentioned masking with respect to the chest. And I know that oaks have interesting masking behaviors. Can you tell me a bit about how that works?

[00:29:37] Why they work the way they do and what the importance is?

[00:29:41] Doug Tallamy: Uh, I will tell you how it works. Why it works is still a little bit up in, up in the air, but masking, of course, is, is the irregular production of, of acorns. Some years they make a whole bunch and they do it in a coordinated way, particularly within a group.

[00:29:56] So in 2019, in the east here, uh, the, all the members of the Red Oak group. had a mass from Massachusetts all the way down to Georgia. It’s a giant production of Acorns. Uh, so you know how they coordinate. Nobody knows.

[00:30:09] Michael Hawk: And that’s different species too, right? In the Red

[00:30:11] Doug Tallamy: Oak group? Within the Red Oak group.

[00:30:13] But they were different species, right? But then other years, they produce almost no acorns. So there’s four hypotheses about why they masked and, and the most popular one. And they’re not mutually exclusive either. Uh, they all could be happening at the same time. One is predator satiation. We’re gonna make all our egg corns at the same time and there simply won’t be enough egg corn, eight eaters out there so that there’ll be some leftover and would germinate new Blue Oaks.

[00:30:38] And along with that comes predator reduction. When you, when there is a mass year, the, the population of mice and acorn weevils and, and acorn moss, the things that depend on these acorns a lot, those populations explode. Well, if next year there’s almost no acorns, those populations crash and, and it’s usually several years.

[00:30:57] There’s very few egg corns before you have another mast year. And it keeps those egg corn eater populations much lower so that when there is a mass, it exceeds what those, those things can. Another hypothesis is oaks are wind pollinated and if they all produce, uh, a lot of pollen at the same time, which you need for a mask, it improves pollination.

[00:31:19] The wind pollinated plants, it’s all by chance does the wind blow the pollen to the right from the male part of the flower to the female part. That’s a hypothesis. Another one is energy allocation, that there’s not enough energy to go around. So some years oaks put the energy into growth and other years they put it into acorn production, but rarely do they have enough energy to do.

[00:31:39] all of those together have been offered as explanations for why they masked. And one question I get all the time is, when’s the next mask ? That’s the part that, that nobody is good at predicting. And it’s because it’s not just the amount of energy you might have all the energy you need to mask, but then the weather’s lassy.

[00:31:56] So if you have a late freeze or a really rainy period during when, when the male catkins are out, you won’t have a mass. It destroyed, uh, pollen, uh, spread at, at that point. I am intrigued by the size of the nine 2019 mast because the weather was not the same in Massachusetts all the way down to Georgia.

[00:32:15] So it wasn’t coordination with rain or cold or frost or any of the other things that could coordinate locally, but they masked it anyway. So that’s why I say people are still, they scratch their heads a little bit. We don’t know when the next mass is gonna be. I thought there’d be a white oak mass this year.

[00:32:31] Nope. Hardly anything out there. Everything was perfect, but there’s still not out there so. . Don’t ask me . Uh,

[00:32:38] Michael Hawk: it’s fascinating. And uh, I imagine there’s lots of people working on that, trying to devise studies, research, observation, to try to figure that out.

[00:32:49] Doug Tallamy: Well, you know, you’d be surprised what people are not working on, and it’s all because of funding.

[00:32:53] These are interesting questions, naturalistic questions, but it’s real tough to get, get natural history funded these days. People say, get your grad students to do it. Well, my grad students cost $30,000 a piece, you know, and somebody’s gotta fund that, and it’s got to be something that they care about. And natural history questions are not, you know, it’s all molecular these days.

[00:33:14] And, and that’s where the, the big money goes. So I actually would be surprised if anybody’s working on why, why Oaks?

[00:33:20] Michael Hawk: Yeah. Interesting. And a little bit disheartening , unfortunately. Uh, I, I maybe, you know, I was thinking as you were talking about that and the fact that there’s a synchrony across species within a group, across a large geographic range, sort of independent of weather.

[00:33:36] It was reminding me a little bit about the stories in the mainstream this year about the periodical cicadas. And, you know, they, you know, that’s a little different scenario because it’s, uh, you can time it pretty accurately to, uh, to the year and maybe, hopefully that has triggered a curiosity out there somewhere.

[00:33:54] And, uh, and someone’s gonna say, yeah, well what about those oaks? And, and go and, and do those studies.

[00:33:59] Doug Tallamy: Maybe, you know, the leading hypothesis is exactly the same. Why, why do cicadas spend 17 years underground? Because when they come out, there is no predator out there that’s numerous enough to be able to eat them all.

[00:34:12] So it’s predator, satiation, uh, you’re right, you can time it very well to the year. Um, we had a good, good cicada emergence at, at my house in, in, in Newark, Delaware, and this whole area this year. And, and I was impressed because 17 years ago there was an emergence and it wasn’t that good. And I, I said, oh boy, they’re, they’re decreasing.

[00:34:33] They’re gonna disappear. Everyone that came out in front of my building 17 years ago, the squirrel sat there and ate them. And I said, boy, this is gonna, this is the end of the cicadas. No . Somehow they, they laid enough eggs. There was a big emergence this year, and it was bigger than most people suspected.

[00:34:51] So, so they did well over the last 17 years. And that’s, you know, when anything’s doing well, uh, I That’s encouraging.

[00:34:57] Michael Hawk: Yeah. Great to hear. So one thing that’s really intrigued me about oaks is the fact that they support so many different gus or insect gulls, and I would be interested to hear your speculation, uh, onto why that would be the case.

[00:35:15] Doug Tallamy: That’s another, another tough question. There are about 5,000 species of CIP gus in the world. Most of them are associated with oaks. There’s, you know, it’s, it’s very fancy physiology to be able to produce, uh, a gall. People have likened gus to cancerous growths on plants, but I don’t like that analogy because cancers grow.

[00:35:35] I mean, tumors just keep growing in an uncontrolled way. Gus are, are extremely controlled and they grow in a very specific species specific way because of the hormones that the female wasp injects into the buds of the. The ma thematic tissue. The butt of an oak is like, like stem cells. You can make it into anything you want.

[00:35:57] And they inject, uh, hormones in different ways that create the shape and the size of this species specific gall. So it’s, it’s highly defined. You can identify what species of wasp it was that made the gall just by the shape of the gall. Why there are more gulls on oaks. I guess the ability to manipulate Gaul masto tissue is just easier than with other plants.

[00:36:20] I’m totally guessing at this point. Uh, but it was an, an evolutionary path that took off. There was an awful lot of speciation, and it’s not just the gallers that are on oaks. It’s the parasitoids associated with the gallers because cip GWAS support more species of natural enemies. Parasitoids, other species of was towas and a number of other families than any other type of insects.

[00:36:45] Why is that? I’m not sure about that either. They’re sitting ducks, you know, they don’t move. So they’re an easy target. Uh, and much of the morphology of the gall is designed to protect the galler within that gall from its natural enemies on the outside. Uh, so it’s some very clever things there. There’s a galler you can have a goal with, with 10 different chambers.

[00:37:07] And the galls, only guer is only in one of those chambers. The other nine are empty. So , the gall, the parasitoid has to figure out which one it is. It’s got a one in 10 chance of hitting it right. The distance. Most of the galls often hollow, so the galler is right in the center of the gall, and there’s a big space between where the galler is and the outside of the gall.

[00:37:28] And that space is designed to separate. The Parasitoids with their OPOs from the galler. It’s a bigger space than any parasitoid can reach with its opoter. So as the galls growing, which it grows very quickly in the beginning, that’s the only time it’s vulnerable to parasitoids because it’s the only time their opoter can actually reach the, the galler.

[00:37:49] So lots of interesting things there, and it does happen on other plants. Rose c uh, supports a number of gallers, but oaks more than anything else. And, and why that is? I, I don’t know, ,

[00:38:00] Michael Hawk: I think finding gulls is a ton of fun. I love to go out looking for ’em because some of them can be just really beautiful and ornately shaped.

[00:38:07] And then when you think about the life history that’s going on there in that little, I like to call it like a little castle for the larva, uh, that the plants created based on this injection. So you said something that, that I hadn’t really thought about before is when, when I find galls, sometimes the gulls are on a leaf.

[00:38:26] They may be like on the midrib of the leaf or, or something like that. Sometimes they may be at the junction on the stem. They’re, they’re stem gus as well. Uh, in every case. Is the hormonal injection occurring on the bud, or, or are they able to induce this growth on more mature tissues?

[00:38:44] Doug Tallamy: No, it always is an, an undifferentiated matic tissue.

[00:38:49] So this very brief period during, uh, the season of, uh, uh, you know, oak growth, that they’re vulnerable to gallers. It’s, you know, it’s, and it takes about five minutes for the female to lay an egg in the, in the gala. So it’s a very brief period of time, just as those buds are, are expanding. Uh, and I have felt very fortunate that it’s always been a goal to go out and find a, a guer when it’s laying its eggs.

[00:39:14] Uh, I’ve done it, I’ve done it twice just because I walk outside and look at my buds. frequently in, in April, but very easy to miss then. A lot of oaks have a second period of growth, and maybe early July, depends on where you live. And it’s not nearly as big, but there’s a second flush, and that’s another time that they’re vulnerable to galls.

[00:39:34] Uh, most gallers have two generations a year and, uh, it’s called alternation of generations. So the first generation is parthenogenetic, meaning there’s no males. All females produce they reproduce without, without mating. The second generation is sexual. So there are males and females, and what’s interesting is the gall produced by the first generation looks entirely different from the gall produced by the second generation.

[00:39:58] And the galler within the gall looks entirely different from the galler from the first generation. I’m still amazed that those early taxonomists ever figured out that they were, they were dealing with the same species because both the gall and the was look entirely different. But it is the same species.

[00:40:14] So it is really incredible. And they didn’t

[00:40:16] Michael Hawk: have DNA to help them . They didn’t have dna. That’s right. . Yeah. It, it really is fascinating and it’s one of those things that I like to use Gus as a hook for people that maybe are overlooking nature, just to kind of open their eyes about the complexity and the, uh, and the nuance that exists.

[00:40:33] And it’s a little counterintuitive to some, because yeah, a lot of people, when they think of insects, they, they kind of have like a, a gut adverse reaction to that. What I try to do is I, I try to find the prettiest reddest. Looking berry of a gu or a leaf just covered in these, and I don’t even tell them what it is and, and just ask like, what do you think this is?

[00:40:58] And take it that direction. It’s a lot of fun. It’s a lot of fun to see the different reactions that people have when they see this.

[00:41:04] Doug Tallamy: Yeah. Another aside about gala is they played a very important part in our cultural written history because, uh, particularly in Europe, although we have the same gall here, there’s a gall that if you grind it up into powder and you add particular chemicals, it turns into a black ink.

[00:41:22] And that was the ink that recorded history was written on for, for, you know, more than a thousand years. The Bible was written with Ga ink. The Magna Carta was written with Ga ink. You know, all the scribes during the Middle Ages used GA ink. The Declaration of Independence used GA ink, so you know, it. We wouldn’t know what was happening with humans if we didn’t have those Gauls making that ink.

[00:41:45] Interesting. Yeah.

[00:41:46] Michael Hawk: Yeah. I had no idea. And, and if those goals didn’t exist, it would probably be some inferior ink that just, you know, went invisible over time and all those stuff gives me lost . Yeah. Fascinating stuff. And, and as I was telling you a little bit earlier, I am still attempting to get a gall person or have a gall centric show and I, I look forward to that in the future.

[00:42:09] So to the listeners, bear with me. I’m working on it. So, you know, the other thing when I think of you, aside from your latest book is just the advocacy you have for personal properties and treating them as habitat. And we started to get into that a little bit earlier, but you’ve coalesced a lot of this into this interesting project called Homegrown National Park.

[00:42:31] Can you tell me what that is? Right.

[00:42:34] Doug Tallamy: You can look at government websites to see how land use is, is, uh, distributed across the country. And between 46 and 48% of the country is in some form of agriculture. So that leaves 54%, which I call the urban suburban matrix. So it’s this matrix of cities and suburbs in all our developed area, all our hardscape and dotted in there, all those little parks of preservers, those little, you know, little patches of woods.

[00:42:58] And so it’s a huge part of the country that is not protected. It’s in this matrix of land use. In 2005, uh, there was a study that said we had 40 million acres of, of lawn in this country, which is bigger than the size of New England. That was 2005. That figure has not been updated. So you know, it’s more than 40 million acres now.

[00:43:20] And I remember sitting at my kitchen table and I read that and I said, well, what would happen if we cut that area in half? So if everybody took half the area of lawn they have and planted it, um, how big an area that would that be, would that be 20 million acres worth? And I started to add up the area of all the big national parks in the country.

[00:43:39] and even through in areas like the Adirondacks, not a national park, but it’s a big area. So Yellowstone, Yosemite, you know, the s Smokey Denali, all these things, you add ’em up. Still less than 20 million acres. So I said, well, gee, we’d have the biggest national park in the country. We could call it Homegrown National Park if everybody cuts their grass in half.

[00:43:59] And that’s how I came up with the idea. That was a long time ago, and I talked about it in my talks, but it wasn’t until I wrote Nature’s Best Hope that I actually made a chapter out of it. So, uh, it was a chapter called Homegrown National Park, how we need to, to work together in order to preserve this, this, you know, 20 million acres that right now is in an ecological dead scape.

[00:44:20] There are four things that every piece of property has to do. You’ve gotta manage the watershed, you’ve gotta support a food web, you’ve gotta support pollinators, and you’ve gotta sequester carbon. Long is the worst plant choice for all of those. Uh, so boy, we can do, we can do better. And that’s what motivated this idea of homegrown National Park.

[00:44:38] Before Covid, I gave talks all over the place and there was a woman, Michelle Berry, sitting in the audience who had just retired from some kind of marketing job in Manhattan. She’d lived 40 years in Manhattan. She was not the choir. So her friend had taken her to this talk. She came up to me afterwards.

[00:44:57] She said, you gotta talk to the non-core here. You gotta get beyond the people who are already on board if you’re gonna realize homegrown National Park. And I said, yeah, people have told me that in the past. I said, but I’m not a social media guy. You know, I, my plate is full. I just can’t do it. And she said, I’ll do it.

[00:45:15] So, so finally I said, okay, cuz other people have suggested that. And, and she has, she created this, you know, our website, homegrown national park.org, this idea of getting on the map. So there’s this map of the US and you can go to your county and your area put in where you know the information of where you are and the amount of area you’re going to plant in natives, or you already have and protected.

[00:45:38] And then we see this national effort to reach the 20 million acre, uh, goal of cutting the area of lawn in, in half. The idea is to raise awareness among people who don’t understand that their property is important piece of the future of conservation. Uh, it’s to motivate people, it’s to make it easy, give them, give them, uh, ways to get started and help them stay engaged.

[00:46:01] And so far we have, I guess we’re up to 9,000 people who are on the map. Not quite at 20 million acres yet, but we’re, we’re working on that. So, you know, I, she, she said, oh, this is gonna work great. And I had, I had lots of doubts. , but somewhere she’s, she’s more or less right. The biggest problem now is it’s too successful because it’s way more than she can handle and I can’t handle it.

[00:46:22] And you know, it, it’s this, it’s a nonprofit that needs the support of a real nonprofit, and that means generating money and everything else. But the concept is working people. When the, when people read these scary headlines about all the, you know, the biodiversity decline and I say, there’s something you can do about it.

[00:46:40] They get excited. It, it empowers them and it empowers them in doable ways. You know, what could one person do? One person can shrink their lawn. One person can get rid of their invasive plants. One person can, can turn out their lights. That’s a major cause of insect declines at night. One person can put in a pollinator garden.

[00:46:59] One person can do that on their property and really revitalize their little local ecosystem. Enhance their real local ecosystem rather than degrade it. Because right now the way we landscape degrades everything around us and that one person becomes an a really important part of the future of conservation.

[00:47:18] That’s the idea. Bet behind homegrown national part.

[00:47:22] Michael Hawk: I love the idea for a bunch of reasons and it reminds me of when I first read Nature’s Best Hope. You know, I didn’t know what to expect. I was actually afraid it was gonna be a doom and gloom sort of story and it was actually very inspirational. While, yeah, there’s some hard statistics and some hard facts in there.

[00:47:40] You do a wonderful job of weaving in. Now this is what we can do about it to that narrative and my own personal story I was telling you just a, a bit about it was, uh, you know, I’ve always been interested in. But I’ve like so many people, I would go somewhere else to experience nature. I’d go on a hike or, or go on a trip even and go out of state.

[00:48:00] But then when covid hit, okay, I still need to get outside, you know? So I would go in my backyard and started paying more attention to my birds. And then I noticed these little flies and I said, what are these things? Oh, they’re hover, fl. And wow, they’re really beautiful. They, they have these ornate patterns and they’re beneficial.

[00:48:19] And, you know, one thing led to another and pretty quickly I realized that all the action was centered around just a couple of native plants. Uh, and for me, California coffee berry is sort of the all-star of my backyard. Uh, I haven’t actually taken the time to tabulate the number of species I’ve seen associated with it, but it’s easily over a hundred.

[00:48:38] And, yeah, it’s, it’s, it’s amazing. It, it turned the light bulb on for me personally, despite having heard messages about the importance. But I could see firsthand that I was helping establish connectivity for insects, food sources. I found Leaf miners, I found Gus, you know, all of these different things that I thought only existed out somewhere else right here in the yard.

[00:49:03] Doug Tallamy: Another common question I get. My yard’s so small, you know, it’s too small to do any of the things you’re talking about, and there’s no doubt that the bigger the area we address, the, the more effective it’s going to be. But your yard’s attached to another yard, which is attached to another yard, if you are the only person in the country that does this, you’re absolutely right, won’t work.

[00:49:24] But the goal is to actually get to a tipping point, a threshold where it becomes the normal approach to landscaping rather than the outlier approach. So that people who might be reluctant, uh, in the beginning will do it just because they wanna be like their neighbors. We want to fit in. And you see this in California, you know, with the long conversion programs just because of the lack of water.

[00:49:48] You know, now the guy with the big green lawn is the pariah because, you know, you don’t have the water for that lawn. Whereas the, the, you know, well-designed Zurich landscape is obviously the future. So you can tip it, you can tip it pretty, pretty quickly. That change was made simply because of the lack of water.

[00:50:05] But, uh, if we understand the lack of biodiversity is not helping us, we can do the same thing. You

[00:50:11] Michael Hawk: mentioned a few of the impediments that homeowners might have in reducing their lawns. In particular, it doesn’t match the traditional like 1950s, 1960s societal view of what a yard should be. And in fact, a lot of the times, yard and lawn are used interchangeably, which kind of shows how people think about it.

[00:50:28] Mm-hmm. . And there’s also the dependency on pesticides in most long care and the corresponding fear that insects might come along if you stop the pesticide use. So what do you think of that? Is that a real fear that people should have? .

[00:50:44] Doug Tallamy: Oh, it’s a real, it’s a, it’s a real fear. Uh, it’s unfounded, but, uh, homeowners use a tremendous amount of pesticides.

[00:50:52] Look at the pesticides available in the hardware store. Just walk down the aisles, you know, product after product, your product, how you can kill all the insects in your yard, in your house. We hire Mosquito Joe to, to drive down our street and fog everything, which kills everything, not just mosquitoes, uh, because we saw Spider , the Spider Eats, mosquitoes, you know,

[00:51:14] So, so the fear is, is real for the most part. It’s unfounded. There’s really only one insect that homeowners need to worry about, depending on where you live. And that’s termites. Termites really do eat your house, and you really do need to control them. Everything else is, it’s anthropophobia, you know, I saw an insect, or I saw a spider, so I have to kill it.

[00:51:36] why is that? You know, it’s not gonna hurt you. It’s our cultural perception of arthropods. Look what happens when the, the giant Asian Hornor Hornet comes to Washington state. It’s labeled the murder hornet. They don’t call it that in Asia. You know, it’s just sensationalism. It really hasn’t murdered anybody.

[00:51:54] Um, and that’s the perception that the media gives us about nature all the time. It’s gonna hurt you in some way. So we have to get past that. We have to stop demonizing it and realize that we can’t live without it. People. , you know, they, they don’t wanna use Roundup to control, uh, an an invasive plant, but they have no problem at all with hiring mosquito Joe or coating their house with insecticides because something might be in there.

[00:52:20] Um, they live in this envelope of poison. They fertilize their lawn, not realizing that there’s a blood leaf, uh, herbicide in that fertilizer that kills all, everything except grass. We live in, in an environment of poisons and don’t seem to mind that. And it’s mostly, it’s out of, out of ignorance. And that’s why I, I write the books trying to get past, uh, the, you know, the myths and, uh, all the, the social paranoia that’s out there with a few.

[00:52:48] A few facts. I think it’s, I think it’s working, you know, it’s real hard to change culture, but I do see, I see change. I’m gonna look at this. You’re doing a podcast with me. This wouldn’t have happened 10 years ago, . It really wouldn’t have.

[00:52:59] Michael Hawk: And I’m, I’m still just ecstatic that, uh, that I’m talking to you, to that point.

[00:53:03] So thank you again. I was just thinking as you were describing this, I was visiting some relatives just a few weeks ago and pointing out some of the interesting things in their property. And, uh, I don’t you to remember which plant it was, but, but I found the plant and I was like, oh, wow, cool. Look at this.

[00:53:18] There’s a leaf roller in here. And, and there were a bunch of ’em actually. And so I pointed it out and I won’t name the, the person that they’re like, oh yeah, it’s time for me to spray again. Like, what? , that wasn’t my point. .

[00:53:33] Doug Tallamy: Well, people, people ha have this idea that if anything touches a plant, plant’s gonna die.

[00:53:40] I have a part of an old talk actually, where I, I walked around the oak that I feature in, in the, uh, oak book, the white Oak company front yard. And I count the caterpillars on the lower branches. I think, I think it was 410. It was 410 caterpillars just on the lower branches, not climbing ladders or anything else like this.

[00:53:58] And then I stood back and took a picture of the tree and I said, can you see any of those caterpillars? Not one. Do you see any caterpillar damage? No. And that’s the distance that we view our trees from. We we’re not up inspecting every single leaf because you will see some holes in the leaves. But it’s, it is normal for these plants to pass on their energy to support all of this biodiversity.

[00:54:20] And if they don’t, you have a dead landscape. There’s a woman in, in, uh, new Orleans, TA Baumgart, who suggests that we practice the 10 step program. Everybody should take 10 steps back from their plants and all their insect problems disappear then. And I think it’s, it’s excellent advice because it’s in our minds that there’s a problem.

[00:54:39] There really isn’t.

[00:54:41] Michael Hawk: Some of my most interesting backyard observations have been, say, I’ll notice a small aphid outbreak somewhere. It doesn’t take long. You know, the aphid just suddenly are there. And then I’ll come back a couple days later and look and they’ll all be gone and, you know, what do I see?

[00:54:59] Maybe some aphid carcasses, some wash, some parasitoid wash found them. Uh, or in other cases, kind of in the intermediate step, I find lace wing eggs just all around the aphid outbreak. So when those eggs hatch, the larva are there with a few days of meal for them. So it’s sort of as, as self-correcting if you just let it.

[00:55:22] Doug Tallamy: and if you had sprayed, you would’ve killed all those predators first. Mm-hmm. , , nakeds are far more resistant to the spray than the predators are in the parasitoids. And then you have to keep spraying cuz you have no natural enemy. Yeah.

[00:55:34] Michael Hawk: So there’s a bit of a leap of faith to, to stop the spraying and let things normalize.

[00:55:40] And it might, it may take a couple cycles.

[00:55:42] Doug Tallamy: Well, it ties in with the perception that you have that, that plants are decorations. You don’t want anything to touch your decoration or it won’t be perfect, but that’s not real life, you know? And, and the object is to have a balanced ecosystem in your yard where you’ve got the plants that support the herbivores, but then those herbi wars support the natural enemies.

[00:56:01] And in the long run with a couple blips here and there, it will stay in, in balance. Your yard will not be defoliated and it will support life.

[00:56:10] Michael Hawk: So does Homegrown National Park, does the website offer any pointers for people to, who maybe are searching for native plants? Uh, or is it more of a tracking resource?

[00:56:20] Doug Tallamy: Well, it’s definitely a tracking, uh, resource. Problem with recommending where to get your plants is that changes mm-hmm. all around the country in, in, in a very fine scale manner. But I, I will say that the, uh, national Wildlife Federation is doing exactly that now. They’re working on a resource that will direct people to the closest source of, of native plants and make it a lot, lot easier.

[00:56:44] So that information is, is out there and will be more out there in the near future, certainly than it was in the past where it, it could be a, a bit of a challenge to find

[00:56:52] Michael Hawk: these plants here in California. The California Native Plant Society has, uh, a really nice website where you can find what grows locally and you can search based on a lot of parameters.

[00:57:03] And then they also link to native plant growers. I haven’t found such a good resource elsewhere, other than like, I think Audubon Society can help you identify some plants based on your zip code. Uh, but that doesn’t tell you where to buy ’em. So yeah, it’s, it’s, it’s extra effort. And I guess that’s the next.

[00:57:19] Frontier in this problem space is making it more of a seamless sort of, uh, endeavor to go find the plants and get the plants and also have some assurance that they aren’t pre-treated with pesticides. .

[00:57:31] Doug Tallamy: Yeah, that’s a challenge as well. I wanna second your, your shout out to the California Native Plant Society and their tool, which is called Cal.

[00:57:39] It is by far the best in the country in terms of, of identifying what plants you should be putting in your yard. They’ve got every single species of plant in California geo-located, so you can pull up the species and look at exactly where it grows. California has so many biomes, you know, it depends on, on where you are in the state, whether you’re on the right or the left side of the, of the mountain, how, how high you are because the plant-like changes totally, very quickly.

[00:58:06] So this is invaluable in helping people find out what they should be putting in their yard. And there’s no other state that has that research at that level. So, um, it’s a, it’s a great thing they have done.

[00:58:17] Michael Hawk: So to wrap things up, uh, I just have a couple of quick questions that I like to ask a lot of my guests and you know, one is in all of your outreach efforts over the years, through the, through your talks, presentations, what have you found?

[00:58:33] You know, maybe, maybe there’s one or two or three, I don’t know, but what have you found to be most effective in helping people sort of move up that ladder of ecological care? Like, it, it could be somebody who has been oblivious and now suddenly they’re engaged. Or it could be somebody who’s already highly engaged and now they’re, they’re volunteering their time and taking it to the next level.

[00:58:53] Like, have you found any tools or stories or, or anything else that’s,

[00:58:59] Doug Tallamy: I try to use, uh, every tool and story I can think of because people are different. Most people do not like insects. Uh, most people have never thought about caterpillars. I’ve had people sit in the unis. I could still remember a lady sitting in the front row and every time I showed a picture of a caterpillar, she covered her eyes and said, you know, I will not look at it.

[00:59:17] You know, so that’s a big barrier to, to overcome. So I don’t call them caterpillars, I call them bird food, and that changes everyth. because there’s like 70 million people in the country that feed the birds. They care about what the birds have to eat and they, everybody thinks birds eat seeds and berries, period.

[00:59:33] They said no. They actually eat insects when, particularly when they’re reproducing. And you can’t put the insect feeder out there except you can, you call it a plant. And it makes it, and all of a sudden they say, oh, like, okay, now I see that my plant actually is doing something, so I try to use hooks, bird.

[00:59:49] You know, birds are a definite hook lately, really, these terrible headlines that people are seeing are been, have been huge motivating factors. I have been surprised when the, the headline about insect apocalypses here, they’re, you know, we’ve lost 45% of the insects planet Earth. I didn’t think anybody would care.

[01:00:07] I really didn’t. But I got emails right away from around the country. This is terrible. What can we do? What can we do? I said, wow, okay. You care about this. There are things you can do. You know, major cause of insect decline is like pollution at night. Turn out your light. It’s pretty easy. Identifying what is bothering them is a motivating factor, but it, it differs.

[01:00:30] And, um, you know, I, it was easier when I was traveling around giving talks and I could watch the audience and see what they reacted to because it’s, I can’t do that on Zoom. I’m staring at myself, you know, and that’s the way it’s been for the last year and a half. And try to gauge, you know, what is it that’s, uh, getting their attention.

[01:00:48] But that’s the goal. Find, find a hook that, we’ll, we’ll bring them in. I do tell a story in, in the book about the woman I interacted with, and her father was definitely non-core. He had the perfect yard. His, his goal in life was to keep up with the Joneses. His yard had to be, his lawn had to be better and perfect.

[01:01:05] And every plant was non-native. And it was all about show. Uh, make a long story short, uh, she got involved in trying to save the monarch and she kept asking him to watch her kids as she went off and worked on Monarch, Monarch watch and all these projects. And finally he said, what are you doing with the Monarch?

[01:01:21] He said, you know, you know, they’re disappearing and planning milkweeds and everything else. So he said, well, why don’t you put some milkweeds in here along the back fence? She said, whoa. Okay. So she put in a whole row of milkweeds in the back fence, and he started to, to immediately the monarchs came and he called, there’s a monarch.

[01:01:38] It’s laying eggs. You know, I think we need more milkweeds here, . So simply knowing that what was supposed to happen with this plant and then watching it happen, All of a sudden he didn’t care about the Joneses anymore. He wanted more milkweeds, he wanted to help the monarch, and he, he was hooked in that case.

[01:01:52] So it depends on, on the person. But I love that story because he’s the last person I would’ve thought would be moved by the Monarch, but he was. So

[01:02:01] Michael Hawk: that’s a great story. And it just shows sort of the magic of larval food plants. We somehow, the insects find them, and then when it’s a charismatic one, like a monarch, you know, all the better.

[01:02:11] And, and it also, at the same time, I’m, I’m sitting here and it’s always bothered me that it’s called milkweed. Like that is just not an appealing name at all. But these are beautiful, intricate plants and they, they do a lot more than just support monarchs too. They’re, they’re good plants. ,

[01:02:27] Doug Tallamy: we call so many of our native plants weeds.

[01:02:29] And then we wonder why people don’t plant . Right. No pie, weed, New York, iron weed, uh, they’re all, they’re all weeds. And that’s because when the Europeans came over, we farmed very differently. Native Americans farmed, not with monocultures. They had everything growing together, including the, you know, the native plants.

[01:02:46] Everything was native back then. That would come up right in the middle of the corn and everything else. Well, the Europeans know we gotta get rid of all that. And anything that grew in your, your agricultural field was labeled a we, and that’s how they got those names. They were all good native plants. Um, so I don’t, I don’t talk about milkweeds, I talk about monarch’s delight.

[01:03:04] I’ve renamed it, you know, Alan and . Perfect. It’s, it’s a psychological game, but uh, all of a sudden it’s okay.

[01:03:11] Michael Hawk: That’s one of your superpowers is the reframing. I, I see it time and time again and I’m trying to learn how about other projects. Do you have anything else upcoming that you’d like to highlight?

[01:03:20] Anything to point people towards or, or your online presence? Like where can people follow what you’re

[01:03:25] Doug Tallamy: up to? , well, I’m getting old, but probably the biggest goal that we have in, in our lab at this point is one of the things that is, has taken us down the road we’ve gone is recognizing the difference between different native plants and their productivity, discovering this keystone plant concept.

[01:03:44] So we, we know at the Keystone plants are for North America, but that’s it. We don’t know what they’re for any other place in the world. I can’t go to England and say, here’s a list of plants that you really need to start favoring in your restorations. I can’t do that in Brazil. I can’t do that in Germany or Australia because we, you know, nobody’s put that list together, the information’s in the literature, but it’s, you know, it’s a big job.

[01:04:08] Anyway, that’s what I would like to tackle, that I’ve got, you know, I’ve got a helper who, who’s made the list so far. She knows how to do it quickly, but she needs support to be able to do that. But th you know this, this way, the entire planet will know. We cannot plant eucalyptus everywhere. , sorry to refer to that.

[01:04:23] You are in California. Mm-hmm. . But, um, you know, it’s a plant that does well, uh, it does well everywhere, but it supports things in Australia and only in Australia. So, you know, when you look at the statistics in Portugal, it’s something crazy. Like 70% of Portugal forests are eucalyptus. They’re not forests, you know, they’re tree farms that are, that are not supporting anything.

[01:04:47] And India is covered with eucalyptus and so on and on and on. You gotta give ’em the information. These are the most important plants. If you want to help biodiversity, we’ve got these trillion tree projects to, to help, uh, climate change. , that could be great if they plant the right plants. So they need that information.

[01:05:06] That’s a big goal. Learning how to landscape underneath the trees we put in our yards is another really important thing because the caterpillars that are run running, our food webs drop from the trees to complete their lifecycle. They’ve got a wiggle their way underneath the ground. If pupate or they spin a cocoon in the leaf litter that’s under the tree, and in most cases the ground is so compacted.

[01:05:26] There is no leaf litter in its mode and trample and everything else that we’ve created. Ecological traps. The caterpillars develop in the trees and they drop down and and die. That’s easily fixed if we just recognize, you know, we’ve gotta do this. So, you know, this is one of the things we know it’s happening, but nobody’s measured the extent to which it’s killing the caterpillars and what happens when you change landscaping.

[01:05:47] So that’s another project. I’d like to, got a bunch of papers where you’ve already done the, the projects. We’ve gotta write them up, but you know, Spending a lot of time doing this and not that. Mm-hmm. .

[01:05:58] Michael Hawk: Well, it’s a lot of great work and I’ll, I’ll definitely point in the show notes, links to the things that we’ve talked about.

[01:06:05] Anywhere else you want me to, for that matter, uh, so that people can find out what you’re, what you’re working on at, uh, at the university.

[01:06:11] Doug Tallamy: Our important papers are on homegrown national park.dot org. That’s the, uh, the center of activity right now. So you can get pretty much what you want there.

[01:06:20] Michael Hawk: All right.

[01:06:20] So I think with that we can wrap things up. It’s been really enjoyable. I hope you’ve had a good time as well. Yep.

[01:06:25] Doug Tallamy: These are fun. Thanks for the opportunity. Okay.

[01:06:28] Michael Hawk: Thank you.
