In Defense of Plants Podcast

This week we are joined by director of The University of Minnesota Center for Forest Ecology, Dr. Lee Frelich to discuss an invasive species problem that threatens plant diversity and ecosystem functioning wherever it occurs. Earthworms are very powerful ecosystem engineers. They alter the entire structure of the soil, affecting everything that grows there. Invasive worms are changing entire ecosy...

This week we take an even closer look at the world of field guides with science historian Dr. Sara Scharf. Field guides began as a tool for botanists to better understand the plants in their region but they have since grown to encompass all forms of life. Learn how some of the most iconic figures in the world of biology had a hand in refining field guides as a tool and even how the need for educat...

Today we take a step back for a fun conversation about field guides. Field guides are wonderful tools that help us identify the species with which we share the world. In this episode we are joined by Bill and Steve, hosts of The Field Guides Podcast, a funny and educational show all about natural history. The thoughts expressed in this show are based on our experiences with field guides of all kin...

The sandmat spurges probably do not factor into the daily lives of most people. Yet, we walk over them, we trample them, we pull them from our lawns and gardens with little regard to their incredible natural history. The spurge family (Euphorbiaceae) lays claim to many incredible plant species but today we take a closer look at one group in particular: the sandmat spurges in the section Anisophyll...

The name "Hydrangea" most often conjures up images of medium sized shrubs adorned with pom poms of bright blue or pink flowers. Our exposure to this incredible genus is often very limited. This is a shame because the world of Hydrangea is wonderfully diverse. Plant hunter, gardener, and author Dan Hinkley returns to the podcast for an in depth look at the amazing diversity of Hydrangea around the...

Native Plant Trust has one major goal in mind: conserving and promoting New England's native plants. Founded in 1900, Native Plant Trust is America's oldest plant conservation organization. Since then, it has gone through some name changes (Society for the Protection of Native Plants, New England Wild Flower Society) but its mission has remained the same. Join me as I sit down for a conversation w...

The Devonian Period was for plants what the Cambrian Period was for animals. Land plants really started to experiment with new forms of growth some 380 million years ago which led to the establishment of the first forests on Earth. My guest today is Dr. Chris Barry who was part of the team that recently discovered the oldest fossil evidence of forests. As you are going to hear, these forests were...

A zoo getting involved in plant conservation? Sounds pretty radical but that is exactly what the Jacksonville Zoo and Gardens is doing. These efforts are born out of the fact that you can't conserve animals without conserving their habitat and native plants ARE that habitat. On average, plant conservation costs less than animal conservation and has the potential to have much greater impacts for bi...

The movement of species around the globe is akin to opening Pandora's Box. Once an invasive species becomes established, it can be very difficult, if not impossible to get it under control. Every once in a while, however, nature provides us with a solution. In this episode we learn about how the incredibly beautiful ornate bella moth (Utetheisa ornatrix) is keeping some invasive peas at bay in Flo...

With his first book, "Bringing Nature Home," Dr. Doug Tallamy managed to distill decades worth of ecological science into a compelling story of the environmental benefits of native plants. Now he is back with an empowering new book entitled "Nature's Best Hope: A New Approach to Conservation That Starts in Your Yard." In a world full of doom and gloom, Dr. Tallamy's latest book is an uplifting and...

Wetlands have a disproportionate effect on a global scale. Whether you are concerned with habitat, wildlife, or human health, the world needs healthy, functioning wetland communities. Unfortunately, humans have been painfully slow to realize this fact. The last few decades have seen laws and regulations put into place to try and protect and restore wetlands but the process needs ecological science...

Florent Grenier fell in love with plants at an early age but it was a trip to South Africa as a teenager that change the course of his life forever. Florent now dedicates himself to studying the ecology, diversity, and distribution of succulent plants. Five years of intense field work investigating strange pollination syndromes involving long tongued flies has culminated in Florent's first book. "...

Counting the rings of a tree can be so much fun. In the temperate zone, each ring marks a year in that tree's life. However, if you know what to look for, tree rings can tell you so much more.  Dr. Valerie Trouet has made a career out of counting and measuring tree rings. Tree rings offer a surprisingly detailed window back in time and allows scientists like Dr. Trouet to understand everything fro...

For author, gardener, and landscape designer Georgina Reid, gardening is more than a hobby. It is a way of connecting with the natural world. Gardening changes the way we look at and interact with plants in a big way and that is exactly what Georgina wants to tell the world. Her new book "The Planthunter" honors this ideal in a beautiful and touching way. Through conversations with gardeners from...

Today I sit down for a chat with fellow plant podcaster, Vanessa Fuchs. Vanessa is the host of The Royal Botanic Garden Sydney's award-winning podcast "Branch Out."

Containing an estimated 1.4 million specimens that span nearly 250 years of botanical history, the National Herbarium of New South Wales is a treasure trove of botanical information. Recently, the Royal Botanical Gardens Sydney, with the help of many volunteers, has undertaken a massive effort to digitize all 1.4 million specimens and make them available for download to anyone and everyone who mig...

Tiehm’s buckwheat (Eriogonum tiehmii) is a rare wildflower endemic to only 21 acres of public land in the remote Silver Peak Range of Nevada. Out of sight and largely out of mind, this species has suddenly been brought to the forefront of a legal battle to ensure it is not driven to extinction. A proposed mining project is now targeting those 21 acres of public land and, if allowed to move forward...

What's not to love about carnivorous plants? From their bizarre looks to their insect-eating habits, carnivorous plants really break the mold on mainstream botanical assumptions. For my guest today, carnivorous plants have been a life long obsession. Damon Collingsworth grew his first sundew at the tender age of 11 and today is co-owner and manager of California Carnivores, one of the premier carn...

Fed up with disturbance creating corridors for non-native plant invasions onto their landscape, landowners in southern Texas teamed up with Texas A&M University Kingsville to create something special. This was the birth of the Texas Native Seeds Program whose mission is to "develop commercially available, locally adapted native seed sources for all areas of Texas, conduct applied restoration r...
