Margaret Hello, and welcome to Live Like the World is Dying, your podcast for what feels like the End Times. I'm your host, Margaret Killjoy, and I use she or they pronouns. And this episode I'm actually recording immediately after the previous episode with Simon because, as soon as we got off the call, we talked about all of these other things that are worth talking about. And there's just so much to all of this that we thought it might be worth doing a second episode about. You might be hearing this—I don't know when you're gonna hear this as compared to the other part. But anyway, Live Like the World is Dying as a proud member of the Channel Zero Network of anarchist podcasts. And here's a jingle from another show on the network. Duh daaaaa do.

Jingle What's up y'all, I'm Pearson, host of Coffee with Comrades. Coffee with Comrades is rooted in militant joy. Our hope is to cultivate a warm and inviting atmosphere, like walking into your favorite coffee shop to sit down with some of your close friends and share a heart-to-heart conversation. New episodes premiere your every Tuesday, so be sure to smash that subscribe button wherever you get your podcasts so that you never miss an episode. We are proud to be a part of the Channel Zero Network.

Margaret Okay, if you could introduce yourself with your name, your pronouns. And then just a real brief overview for people who didn't listen to the first interview we just did with you about the kind of work you do and what your specialization is.

Simon Yeah, thanks for having me on again. My name is Simon Apostle. I'm a restoration ecologist. And I've been working in Oregon and Washington, kind of across the Pacific Northwest, for the last 10 or so years. And most of my work has focused on reforestation, but also just general natural resource management and ecological restoration.

Margaret So we were talking about—you have ideas about what people who have access to some, you know, maybe homestead-style, size of land or land project or even, like, maybe even smaller scale than that—about what people can do besides just reforestation, what is involved in restoration, and using that to mitigate whether climate change or other problems ecologically?

Simon Yeah, so one of the things that, in our field, we've been looking at quite a bit is how do certain keystone organisms really affect the landscapes. And one of the biggest ones—not just in size, they get pretty large though—is the North American Beaver. Which and this is true across North America. And beaver are a critical component of ecosystems. And they do that by doing what we know they do, by building dams, and altering hydrology in a way that creates habitat, it creates diversity, it retains water in a landscape by damming streams up and creating new channels and all of these things. And so reintroduction of beavers, or by mimicking the processes that beavers create, you can do a lot for the land and also potentially make it work better for you. Because you know, as we face climate change, water retention is kind of one of our biggest issues.

Margaret So you're telling people that they should build dams and cut trees?

Simon That's exactly right. Yeah. If you want to think like a beaver, you should build a dam. If you want to use it for hydroelectric purposes, you can do that. And then, yeah, of course, cut down trees. No, it's a really interesting parallel, right? Because beavers kind of act like us, you know, and they do all these things that we know are—especially in the Pacific Northwest—know are bad. We know that the dams, the hydroelectric dams, are a massive problem for salmon and for other organisms, and disrupting natural water flows and creating barriers and, of course, cutting down trees is the thing we all know is we don't do well. But beaver do things in a way that that they, you know, ecosystem around them has adapted to do and interact with. So a beaver dam—first of all, the scale is different, right, it's not going to be across the Columbia River, it's across a stream, a low gradient side channel, something like that. And a beaver dam is porous, it has water cascading over it, a fish can jump over it. It is complex, you know, there's a pond behind it and there's wetlands on the margins and there's channels flowing around it that they may not have gotten to damming yet. And that complexity is critical, right? Like, it's the taking of a simple stream channel and making it into something really complicated and with little niches for all these different organisms. And it can work for humans too, you know, by recharging groundwater, by retaining water on a landscape for longer you get aquifer recharge, you get, you know, trees surrounding that area, maybe growing a little bit better, all of these things that are directly valuable to us.

Margaret So that's the kind of, like, microclimate stuff of making your area—you're, like, so wells will go dry, slower and things like that.

Simon Absolutely. I mean, water retention in landscapes is so important. You know, as we, like, face climate change, right, it's—and some of that is affected by by climate change directly just through evaporation, but also as you get precipitation changing from snow to rainfall, you know, through a larger portion of the year in a lot of systems, that means that the water's not coming down as a trickle of snowmelt throughout the year, it's coming down, you know, in a single rain of that. And there's none left in the summer. And beaver are one of the organisms that can help counteract that by retaining that water in the smaller streams and then letting it out as a slower trickle.

Margaret It's so wild that that—that something at that small of a scale has an impact. I feel like that's like something that I often forget about because, as much as I'm like, oh, I like bottom-up organizations and blah, blah, blah. I'm like always sometimes forget that something as simple as like blocking a creek can have an impact.

Simon Yeah, and it's the aggregate effect, right, too. It's all of—its every little side channel. And especially if we talk about in a temperate region, like the the Northeast in the US or the Northwest, where you have lots and lots of little creeks. And historically there were probably beaver populations on every single one of those that, of course, were all trapped out, you know, as European trappers moved into those landscapes.

Margaret What—This is it is a question I feel like I should have learned in middle school or something. But why do beavers build dams? Like what's in it for them?

Simon Yeah, so I mean, it's a really good question, right? For them, I think—and actually, this is like, a really interesting evolutionary question because old world beavers, a European, like super similar species. I don't even know how different they are genetically, and I'm sure a little bit, but they don't build dams, t
