Hemlock woolly adelgid (HWA) is an invasive forest pest killing hemlock trees across the eastern United States. You can help protect the future of Adirondack forests by supporting early detection efforts and reporting new locations of this harmful insect. Become a trained citizen scientist and adopt trails or forest stands to survey for HWA. The scouting season typically runs fall through late winter, annually (based on insect activity year-to-year).
