Once the third-most common tree in New York, native hemlocks have been dying at an alarming rate due to the infestation of the hemlock woolly adelgid (HWA), a non-native insect pest. Sometimes called "the redwood of the East," hemlocks are keystone species that stabilize riparian ecosystems and provide shelter, food, and habitat for many native plants and animals. Join NYBG's Plant Health Director Don Gabel to hear about ongoing local efforts to mitigate the loss of this important conifer through biological control, as well as establishing groves of a HWA-resistant selection of Canadian hemlock.
