The DEC Forest Health program is responsible for monitoring the ecological health and function of all of the forests of New York State. The program gathers, analyzes, and reports on tree pest and disease information for forest land owners and managers both public and private. The highest priority is placed on early detection of and rapid response to high-impact invasive species that may threaten the health of our forests.
