To round out Season 3, Melissa and Wythe talk about the concept of the “urban forest” in NYC with scientist Mike Treglia of The Nature Conservancy. Mike was trained as a herpetologist (reptile scientist), but he now focuses on the total ecological systems of cities, especially trees. The Nature Conservancy itself works to study and protect land in many different ways, including in New York City. Mike also works with Forest For All NYC, supporting policy that can create and realize a comprehensive plan for NYC’s treescape. Mike also co-organizes the Green Roof Researchers Alliance (GRRA), with NYC Audubon. The GRRA coordinates research on green roofs in the city, including the mapping of these roofs and helping us know what animals live across these heterogeneous spaces. Mike tells us all about the types of work that different research groups are up to, and how these individual scientific efforts connect with a larger social movement to create green roofs and steward them successfully. We also talk a lot about policy, especially given extreme temperatures and the roles green roofs can play in keeping buildings cooler. (Plus, lightning round: pizza in Staten Island!)
