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.

More about Forest Health:
- Insect, Plant and Disease Identification - Identification of insects, plants and tree and plant diseases
- Hot Topics and Recent Additions for Forest Health - This page contains information on highest priority forest health issues, newly emerging pests and diseases, and recently available data and reports from DEC's Forest Health Program and our cooperators.
- Tree Pests and Diseases - This page can help you find out about the biology, symptoms, hosts, and available control strategies of many of the insects and diseases that can harm trees and forests in New York State.
- Plants that Cause Problems in the Forest - It has been estimated that about 1/3 of all the plant species presently known to occur in New York are non-native. Of these, some have demonstrated the ability to crowd out native vegetation, alter local ecology, or cause harm to people or animals.
- Forest Health Aerial Survey Program - Each year DEC and the NYS Police Aviation Unit conduct a two-month aerial survey of the State's forests to detect possible threats by insects, diseases, human activity and major weather events.
