Ep. 468 - Plants, Structure, and Habitat

In Defense of Plants Podcast ·

2024/04/07

I have said it before, and I will say it again: plants ARE habitat. Nowhere is this fact more apparent than in the field of wildlife ecology. From food to shelter, one simply can't understand the innerworkings of nature without understanding plants. Join me and Wildlife Ecologist Dr. Chris Moorman as we look at why plants are so important to conservation efforts.

Ep. 464 - Back from the Brink

In Defense of Plants Podcast ·

2024/03/10

Good news is hard to come by in the world of plant conservation, but it is out there! Take, for instance, some recent examples on Santa Cruz Island in which the recovery of a handful of endangered plants, including island bedstraw (Galium buxifolium) and Santa Cruz Island Dudleya (Dudleya nesiotica), has been so successful, they have been delisted. That doesn't mean conservationists no longer have to worry. Join me and John Knapp from The Nature Conservancy as we explore the ins and outs of plant

Ep. 461 - Litter Trappers Revisited

In Defense of Plants Podcast ·

2024/02/18

Litter trapping plants don't worry about soil, they make their own! Because so many species in the tropics grow either epiphytically or in nutrient poor soil, some of them have turned to alternative solutions. Their anatomy is such that they collect everything from dead leaves to bird droppings. A diverse community of soil microbes and invertebrates can then go to work to create nutrient rich humus. What's more, litter trapping abilities can be found in plants as distantly related as ferns and
