Ep. 88 - Plant Diversity and Systematics 25.12.2016

Lately I have been thinking a lot about plant diversity. Sure, the early days of plant exploration are long behind us, however, there are still plenty of botanical mysteries yet to be discovered. This goes so much deeper than simple fame and glory too. How can we protect species that we don't even know exist? That is where people like Dr. John Clark come in. Dr. Clark has made a career out of disc...

Ep. 87 - Fire in the Forest 18.12.2016

I have been thinking about fire a lot these days. In the wake of recent forest fires in the southeast, I wanted to take a closer look at what fires mean for ecosystems other than prairies. To do this, I brought on my good friend and lab mate, Tyler Refsland, to discuss the implications of fire in forest ecosystems. Tyler's work is based in the oak hickory forests of southern Illinois and takes a u...

Ep. 86 - Plant Propagation at Kew 11.12.2016

Personally, I think plant propagation is one of the most important skills anyone can have. That is why I was so excited to talk with my guest this week. Rebecca Hilgenhof is a Botanical Horticulturist at the Royal Botanical Gardens at Kew. She has the charmed position of propagation a bewildering variety of plants both for conservation and education. This is a fascinating discussion that I know yo...

Ep. 85 - Plant Conservation in the Modern Era 04.12.2016

When it comes to conservation, plants have largely been overlooked. We tend to spend a lot more time with "charismatic" species of animal. For instance, 100% of the world's known threatened and endangered animals have been assessed by the IUCN whereas we have only assessed about 5% of plants. This is quite scary considering that so-called biodiversity hot spots are defined by their vascular flora....

Ep. 84 - Project Pine Cone and Other Botanical Adventures 27.11.2016

Pine cones are fascinating structures. These scaly organs are the female reproductive structures of conifers. As children we collect them, throw them, decorate them, and even smother them in peanut butter and seeds to attract birds. My guest today takes pine cone collecting to a new level. Renee Popp is retired botanist from the US Forest Service and is the creator of Project Pine Cone. Renee's go...

Ep. 83 - The Sedge-isode 20.11.2016

Sedges. This wonderfully diverse group of grass-like plants can be quite intimidating to those who are new to the world of plant identification. Sedges are to botanists as shore birds are to birders. Because of this, sedges are often glazed over as yet another gramminoid for amateurs and ecologists alike. This is not a good thing as sedges are incredibly important components of healthy ecosystems...

Ep. 82 - Environmental Action: Putting Your Energy to Good Use 13.11.2016

There are a lot of angry people out there. However, sitting on your couch and being apathetic is no good. Join me for a conversation with my good friend Bill Michalek about channeling your energy into environmental action. When Bill isn't teaching he is also co-hosting The Field Guides Podcast, a monthly show that takes you out into the field to learn about the environment. This episode was produc...

Ep. 81 - Contemplations on Biocontrol 06.11.2016

No matter where you stand on the topic of invasive species, they are a force we must reckon with. My guest on this episode is working intimately with the ecology of an invasive tree known commonly as Tree of Heaven. Kristen Wickert is a PhD student at West Virginia University and she is investigating the use of a native species of fungus that is proving to be quit effective at ridding the landscap...

Ep. 80 - Lichens and Their Conservation 30.10.2016

Lichens are everywhere and we hardly ever notice them. Aside from their beauty and interesting symbiotic relationships, lichens are also crucial components of their environment. Today we are joined by Jessica Allen, a PhD student who is devoting her career to understanding and preserving these wonderful organisms. Please join us for a fascinating discussion about the world of lichens. This episode...

Ep. 79 - A Lifetime With Orchids 23.10.2016

Today we are joined by Tom Mirenda. Tom has the unique position of Orchid Collections Specialist for the Smithsonian Institute. At somewhere around 8,000 plants, this is no small task. He has spent his life loving and caring for orchids and when he is not doing that, he is busy lecturing and writing about them. This is a wonderful case in which a passionate hobby has turned into an illustrious car...

Ep. 78 - A Focus On Native Bees 16.10.2016

North America is home to a plethora of native bees. Sadly, they are a bit of a mystery. Overshadowed by non-native honey bees, many of our native species are in serious trouble. That is where scientists like Dr. Alexandra Harmon-Threatt come in. An assistant professor of entomology at the University of Illinois, her lab is focused on the interactions between native bees and the surrounding plant c...

Ep. 77 - Native Plants and the Human Environment - A Landscape Architect's Perspective 09.10.2016

Landscape architects have a unique position. They get to decide the way in which we utilize different plant species in the human environment. The push for using native plants has never been greater and rightly so. Native plants are the cornerstone of a healthy ecosystem. That is where people like Bridgette Moen come in. Bridgette is a landscape architect who has realized the importance of creating...

Ep. 76 - Broomrapes: A Celebration of an Interesting Family of Parasitic Plants 02.10.2016

Parasites have earned themselves a bad reputation in our society. We often see them as nauseating freeloaders. This could not be farther from the truth. More and more we are starting to realize just how important parasites are in any given ecosystem. Not only do they promote and maintain biodiversity, they also serve as vital indicators of ecosystem health. My guest today is Brandi Cannon, a maste...

Ep. 75 - The Question Show! 25.09.2016

It's here! The long awaited question show has arrived. Over the last few weeks listeners have been submitting their botanical questions for me to answer. I got some great questions and it was really fun doing the research in hope of providing satisfactory answers. I cover a lot of cool topics from leaf color to carnivorous plants and even some phylogenetics. This was a really fun episode to record...

Ep. 74 - Plants That Eat Animals: A Conversation With The Carnivore Girl 18.09.2016

While looking for a unique and interesting photography subject, Maria Fulmer set her sights on a Venus fly trap. From that artistic exploration The Carnivore Girl was born. It isn't hard to get bit by the carnivorous plant bug. However, an unfortunate majority of folks who attempt to grow these plants are met with failure. Growing carnivorous plants takes a bit of learning but once your bases are...

Ep. 73- On Milkweeds and Monarchs: The Search for a Smoking Gun 11.09.2016

Monarchs have become the poster child for protecting, conserving, and restoring native flora. Over the last decade monarchs have witnessed massive declines in their numbers. This has led to a lot of speculation as to what might be causing such declines. It seems like a simple black and white issue, monarchs need milkweed and we have plowed over most of the milkweed on this continent. As straight f...

Ep. 72 - In Search of a Peculiar Parasitic Orchid 05.09.2016

This week we go in search of an interesting little parasite. Known scientifically as Corallorhiza odontorhiza, the autumn coralroot orchid haunts the forest floor throughout much of eastern North America. Despite this wide distribution, it is never very common and finding it can be quite a challenge. Not only is it small, it seamlessly blends into the background of forest debris. Join me as I brav...

Ep. 71 - Nepenthes and Other Botanical Treasures with Stewart McPherson 28.08.2016

Getting bit by the carnivorous plant bug can lead to a lifelong obsession with these botanical wonders. That is exactly what has happened to Stewart McPherson. He has dedicated his life to finding, photographing, and naming these amazing organisms. He is especially fond of the tropical pitcher plants in the genus Nepenthes. Over the last decade Stewart has explored some of the most remote corners...

Ep. 70 - The Great Thismia Hunt 21.08.2016

Thismia americana was unique to Chicago. Unfortunately it hasn't been seen in 100 years. That minor detail didn't stop a group of us from heading out to the spot where it was last sighted to see if we couldn't relocate this peculiar little parasite. It is wonderfully uplifting to watch as a group of dedicated volunteers set off into this post-industrial marshland to find a plant no bigger than you...

Ep. 69 - Mallows, Clovers, and Questions 14.08.2016

The Kankakee mallow is getting a lot of attention this month and rightly so. The Langham Island population is flowering for the first time in over a decade! I checked in with Robb Telfer to get some updates on the push for making the Kankakee mallow the official state flower of Illinois. We also get an update on how his leafy prairie clover seeds are doing as he and others attempt to resurrect the...

Ep. 68 - From Seed to Orchid: A Behind the Scenes Look at Orchid Conservation 07.08.2016

Growing orchids from seed is no simple task. It's not a matter of throwing seeds in soil and waiting for nature to take its course. That is where people like Matt Richards come in. Using specific laboratory techniques, Matt has made a career out of propagating rare and endangered orchids from all over the world. His efforts have led to amazing conservation efforts that are working towards restorin...

Ep. 67 - For the Love of Moss 31.07.2016

For Dr. Lily Lewis, a love for mosses came early. This passion for bryophytes has taken her far up into Alaska and all the way down into Subarctic Chile. She has made some incredible discoveries along the way. From the feces of mammals to the feathers of birds, Dr. Lewis and her collaborators have uncovered some incredible aspects of moss ecology no one knew existed. Join us for a fascinating disc...

Ep. 65 - Botanizing the Atlanta Botanical Garden Pt. 1 17.07.2016

The opportunity to go behind the scenes at a place like the Atlanta Botanical Garden doesn't come often. As such, a few of us jumped on the opportunity to do so. Led by their resident Plant Recorder, Mike Wenzel, we were taken on a day-long adventure to explore the myriad plants they have in their collection. The Atlanta Botanical Garden is the real deal and should serve as an example for how othe...

Ep. 64 - Bryophyting 10.07.2016

When you meet someone like today's guest, you hold on to them tightly and make them go hiking with you. I met Sarah Hecocks earlier this summer. She joined our research station as a seasonal avian tech. However, she wasn't into birds alone. Sarah has a deep passion for mosses, liverworts, and lichens alike. As such, we spent many hours in the woods geeking out over the often overlooked organisms....
