Critical Mast: Oak Trees with Zarah Wyly

Critical Mast: Oak Trees with Zarah Wyly

We need every single species of native tree here in California, but our 20+ varieties of native oaks are the most crucial of all. In this episode, join me and my guest, Zarah Wyly, on a walk through a relatively new oak woodland in Folsom dotted with two ancient, magnificent oak trees. Learn the story of how this unusual woodland came to be, find out why oaks are my all-time favorite trees, and explore such questions as: What kinds of life are supported by oak trees? If I plant one, will it wreck my house? What do you have to do to acorns to make them edible? Why does it look like some oak trees are growing apples? How do oaks spread such heavy seeds? What kinds of variety is there among different oak species? What does any of this have to do with the Declaration of Independence?
