The Wollemi pine is one of the world's rarest trees. These mysterious gymnosperms was unknown to science until 1994. Their discovery made headlines around the globe. My guest today, Dr. Heidi Zimmer, has the distinct honor of working with this wonderful species. Join us for a conversation all about Wollemia nobilis.

Eastern North America has two species of hemlock - the eastern hemlock (Tsuga canadensis) and the Carolina hemlock (Tsuga caroliniana) - both of which have been hit by an invasive insect pest - the hemlock wooly adelgid. This pest has devastated hemlock populations in the southern portions of their range and climate change may spell disaster for trees growing farther north. However, there is hope in organizations like the Hemlock Restoration Initiative. I am joined today by Sara deFosset to talk about what communities and organizations are doing to save these wonderful and important trees.

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 goal is to amass a collection of cones from every species of pine on the planet. She uses her collection to teach children and adults about not only pines, but also bigger ideas in botany and ecology. Her stories are inspiring in a big way and I know you are going to enjoy this conversation. The episode was produced in part by Gregory, Mark, Allen, Desiree, Sienna, Laura, Margie, Troy, and Bryan.
