Entomologist, ecologist and author Doug Tallamy returns to the show. He discusses his latest book, The Nature of Oaks and his work to create Homegrown National Park. But he will also talk with Kerry Leigh, executive director of the Natural Land Institute about the continuing threat to Bell Bowl Prairie in Rockford. On the good news front, we'll chat with Debra Behrens from The Prairie Enthusiasts about a grant they just received to expand Mounds View Grasslands Preserve near Madison, Wisconsin.
