The Joshua Tree is perhaps only rivaled by the saguaro cactus as the icon of the desert southwest. Featured on U2’s classic album cover, and now the backdrop of countless instagram glamor shots, its unique, almost alien look is unmistakable.

But for decades the Joshua Tree was looked at with disdain - even loathing and hatred.

Today, our guest is Barret Baumgart, author of the new book, “Yuck: The Birth & Death of the Weird & Wondrous Joshua Tree”. Barret explores the history of the Joshua Tree, in a book that can be considered part history, part natural history, part cultural criticism, and part ecology.

Today, we delve into the strange and winding tail of the Joshua Tree and its history of evading human preconceptions and assumptions.

Living on the edge, it faces a potentially bleak future, but perhaps it will thwart us once again, against all odds.

Be sure to check out Barret on instagram, and on his Substack called Dumpster Fires.

Discover the Jumpstart Nature Podcast - entertaining and immersive, it's the nature fix we all need.

Check past Nature's Archive episodes for amazing guests like Doug Tallamy, Elaine Ingham, and Rae Wynn-Grant, covering topics from bird migration to fungi to frogs and bats!

We love native plants and habit-friendly yards at Nature's Archive, and I have a few exciting updates from my yard: spoiler: native plants are working! 

And stay tuned for a re-air of a classic episode with Leslie Inman from Pollinator Friendly Yards. There are plenty of useful insights for both habitat-friendly yard practices, and community building. Afterall, we need everyone to not only take action, but spread the word.

And we have new episodes around the corner, too. It's been incredibly busy these last couple of months, so thanks for your patience as we work to keep all of the proverbial plates spinning!

On to the episode...

I started Nature’s Archive podcast in an effort to understand the stories of people making a difference for the environment. I needed to be inspired, wanted to learn how they did it, and share that inspiration and knowledge with anyone willing to listen.

While we haven’t strayed too far from those initial aspirations, I do have many more topic-centric episodes than I did at the start.

Today’s episode is a “back to my roots” episode. My guest is Leslie Inman, the founder of the wildly popular Pollinator Friendly Yards group on Facebook. With 184,000 members, it is perhaps the top spot for people to discuss sustainable personal landscaping. And even if you are not on Facebook, it’s pretty likely you’ve seen her images and infographics. 

Leslie’s story is an amazing example of how a little curiosity can be converted into a hugely impactful movement. Today, we discuss not only how the group formed, but the lessons that she has learned along the way. This includes how to “reach” people who may be skeptical about inviting insects to their yards, how to make it easy to get started, and more.

Leslie also has two books - Your Yard is Nature and The Butterfly Egg and the Little Tree.

Today’s episode is about one of the coolest plants that I can think of - both figuratively and literally! 

Stick with me for a moment. When you think of a parasite, what comes to mind? Maybe mosquitoes, ticks, tapeworms. Probably nothing you want to invite into your house or property.

But there are parasites that are super beneficial to ecosystems.

The parasite I’m speaking of is also the cool plant I alluded to. Well, it’s actually a large category of parasitic plants. In fact, they’ve separately evolved on five different occasions. What are they?

Well, mistletoes, of course! 

Dr. David Watson joins us all the way from Australia to talk about these spectacular plants. Today you’ll learn why mistletoes are beloved by birds, provide food for many other animals, are key to nutrient cycling, and why they are literally cool plants.

There are even mistletoes that grow on, get this, other mistletoes!

Find Dr. David Watson on Bluesky.

Have you ever wondered why some rainshowers turn into thunderstorms? Just what happens in the atmosphere to create these dynamic, exciting, and sometimes damaging storms?

I find it fascinating, because so many interesting principles are at play - things we often overlook. Like, did you know that the sun doesn’t actually directly warm the air? Yes, you heard that right.

Today we take a look at how thunderstorms develop, how they can turn tornadic, and of course, I tie this back to ecology. We discuss the three ingredients needed for thunderstorms - moisture, lift, and instability - and how sometimes even that is not enough. And then there is the fourth ingredient needed to create tornadic thunderstorms.

You may know that I’ve been a weather nut since I was a kid. Back in grade school, I was so obsessed with tornadoes that I decided I’d write a book about them. My mom would take me to the library so I could check out every weather book I could find. Then I’d head home, pull out my dad’s old typewriter, and create my own newsletter — Weather Extra. My subscriber list? Just me. But I was hooked.

So I hope you enjoy this topic, a bit different than our typical episodes!

When we think about habitats, it’s easy to picture the rich diversity on land—vast prairies, scorching deserts, lush forests, and intricate wetlands. But what if I told you the ocean is just as diverse, filled with ecosystems as unique and vital as any on land? The only difference? We can’t see them as easily—but that doesn’t make them any less important.

Today’s guest is Dr. Judith Gobin, joining us all the way from Trinidad and Tobago. Judith is a recently retired professor of Marine Biology from the University of the West Indies. 

And she’s here to tell us about tropical marine habitats, such as mangroves, sea grass, and coral reefs. She has a particular interest in deep sea habitats, such as cold methane seeps and even whale falls. It’s a bit morbid, but weighing up to 300,000 pounds, in the case of a blue whale, a dead whale literally creates its own habitat.

To my surprise, I learned that the ocean floor more than 200 kilometers away from national coast lines is basically a free-for-all for exploration and resource extraction. Judi tells us about a new treaty that aims to better control these operations, which can disproportionately harm island nations such as Trinidad and Tobago.

It’s a deep dive into ocean science, conservation, and awe-inspiring ecosystems.

Today’s guest is the brilliant Dr. Wendy Bohon, an earthquake geologist who has a passion for making the complexities of our planet accessible and engaging. Dr. Bohon is known for her dynamic science communication - in fact, you may have seen her viral videos through her Dr Wendy Rocks channels on YouTube and other social media.

Today, Dr. Bohon delves into the fascinating world of geology and earthquakes, exploring their impact on our environment and society.

In this episode, you'll discover how earthquakes occur, how earthquake geologists figure out how often faults rupture through fascinating paleoseismology, and what terms like magnitude and epicenter really mean, and how they can mislead us, too!

And did you know that the Richter Scale is actually no longer used? In fact, it began phasing out of use in the 1980s! What’s replaced it? Check in around 49 minutes to hear the story. In fact, it turns out that earthquake magnitude is a pretty poor way of understanding earthquake impacts. Dr. Bohon has some excellent metaphors to help us visualize what really happens to a fault during an earthquake rupture.

Dr. Bohon also tackles common myths about earthquakes, from breaking down the misconception of earthquake weather to clarifying the real risks of seismic events. For example, did you know that in some respects, people in the eastern United States face greater potential impacts from earthquakes? We discuss how you can prepare.

And can people cause earthquakes? The answer is a resounding yes. But can we use that power to release pressures in fault systems and avoid “the big one?” - well, you’ll have to listen to find out.

 Today's episode was one of the most fun ones that I've done in a long time.

You can find Dr. Wendy Bohon at wendybohon.com, and DrWendyRocks on YouTube, Instagram, and BlueSky, and DrWendyRocksIt on TikTok. I promise you - her content is great, so check her out.

Dr. Jonny Hanson is an environmental social scientist, conservationist, and former community farmer. He's also the author of Living with Lynx, Sharing Landscapes with Big Cats, Wolves, and Bears.

He spent months traveling Europe and the United States learning about the real-life challenges of reintroducing apex predators to landscapes, and how to make coexistence successful for everyone involved.

Today, we discuss Jonny’s travels, stories, and lessons learned. And of course, we begin with “why reintroduce apex predators in the first place”. 

As an environmental social scientist, Jonny spends much of his time learning how to bridge the gaps in how different communities consider living with predators, and by the time we were done, I felt more confident than ever that we can and should allow these magnificent animals back into our landscapes. 

This episode is full of amazing insights, and Jonny seems to be a quote machine. There were so many well stated tidbits throughout that I know I’m going to use in the future.

Not only that, but you’ll get to hear how Jonny actually bred mosquitos for money, and how that influenced him. And if you stick around to the end, you’ll also get to hear about his experience with concentrated bobcat urine.

If you can’t tell, this is a nutrient dense episode, but with plenty of fun stories, too.

Be sure to check out Jonny at jonnyhanson.com, and on facebook, instagram, youtube, and tiktok.

Today’s episode is very timely. Our guest is Margo Robbins, cofounder and Executive Director of the Cultural Fire Management Council. Margo advocates for the return of cultural burning practices as a way to strengthen community, support biodiversity, and mitigate out of control fires that plague so many areas.

But before I get further into the details of today's episode, I want to note that it was recorded just a few days prior to the tragic and devastating wildfires that affected the Los Angeles area in January. 

We’ve had numerous interviews on Nature’s Archive with wildfire and prescribed burning experts, so if you’ve heard any of those, you know that fire frequency, intensity, and management practices vary dramatically depending on what habitats and climates we’re talking about. Los Angeles is predominantly shrubland and chaparral, which has been invaded by numerous invasive grass species, further enhancing fire risk.

Today’s episode focuses largely on the forested lands of Northern California, specifically, Yurok tribal lands. So while the topics discussed here may apply to other habitats, the specifics will vary.

Despite all of the past episodes relating to wildfire, we’ve had a notable gap - that is, no one has been able to speak to traditional indigenous use of fire. That is, until today.

So today you’ll hear why cultural fire is so important across so many dimensions of life. You’ll hear how cultural fire can be safely practiced, and how it has strengthened the Yurok community. 

If the idea of purposeful fire being beneficial to the land is new to you, I invite you to check out episode #89 with Lenya Quinn-Davidson - it’s one of our most popular and provides good baseline information for today’s episode. In fact, we have several other episodes that discuss wildfire, prescribed burning, and more - all are listed below.

I was incredibly grateful for Margo spending the time with us today. I hope you enjoy this episode as much as I did.

As a nature lover, I’m often asked about my favorite plants, animals, and insects. And I always struggle to answer those questions, because I have so many favorites, and they are context dependent. But when it comes to birds, woodpeckers often come to mind first. 

They’re often colorful, charismatic, and have such an amazing set of adaptations that let them drill into trees, excavate insects from bark, and some even fly catch on the wing. 

One of the most interesting woodpecker species is the Acorn Woodpecker, found in much of the west and southwest. They live in large groups, are loud, have a clown face, and can store thousands of acorns in specially drilled holes that are just acorn sizes.

Today’s guest is Dr. Walt Koenig, who has spent several decades studying these birds, in affiliation with the Cornell Lab of Ornithology and UC Berkeley. Today we’ll learn about their behaviors, why you don’t find acorn woodpeckers in the east, despite a nice variety of oak trees, and get this - acorns aren’t even their preferred food! 

Dr. Koenig has studied their breeding behaviors and group compositions, which is perhaps the most fascinating part of the interview, and I can’t do it justice in a short intro - so you’ll just have to listen.

And if one studies acorn woodpeckers, it follows that one studies acorns, too. So we also discuss the phenomenon of masting - that is, when oak trees produce bumper crops of acorns, in synchrony across wide geographic ranges! In fact, this past year was a mast year for some oak species in California. So if you are interested in what causes masting, you might want to jump to the last 23 minutes or so of the interview.

Slime molds (Myxomycetes) are beautiful, weird, and amazing organisms. Often mistaken for fungi, they are actually single celled, yet they grow and efficiently move in search of food, can start and stop their life cycle based on environmental conditions, and even change colors several times during their brief life cycle. They can be beautifully colored, frequently iridescent, and can be ornately shaped. And better still, they can be found in much of the world - maybe even in your yard.

My guest today, Alison Pollack, is a renowned slime mold photographer and unabashed enthusiast of slime molds and their habitats. If you follow nature photographers on Instagram, perhaps you count yourself as one of her nearly 60,000 followers.

Today, Alison tells us what exactly a slime mold is - and no, it is not a mold or fungi. She tells us about their fascinating lifecycle, where they grow, and how to find them. 

Alison then tells us about her astonishing macro photography of slime molds - both in the field and in her home studio. She walks through her process, technique, and equipment she uses to create her acclaimed photos. If you do nothing else, follow her on Instagram @marin_mushrooms, or check the photos below to get a hint of the beauty of the slime molds, and Alison's artistic skill in capturing them.
