Yorktown: Lecture on native plants and wildlife, with Doug Tallamy, author of “Bringing Nature Home,” will highlight the unbreakable link between native plant species and native wildlife. A growing number of people are landscaping with productive native plants to help conserve local biodiversity, but many know little about the animals they are helping. Tallamy will describe some of the fascinating ways animals interact with the native plants they depend on. Anticipating, observing, and understanding these relationships will enrich our lives and further justify the use of natives in our yards. By planting natives, everyone can provide a welcoming environment for wildlife. Limited spaces available. Register at 914-762-2912.
