Hemlock Health Monitoring Plots & Hemlock Woolly Adelgid (HWA)

  • Tuesday, February 10, 2026, 2:00 PM - 4:00 PM

Hemlock woolly adelgid (HWA) poses a serious threat to New York’s forests. One important conservation strategy is identifying and conserving hemlocks that may show natural resistance. In this session, participants will be introduced to The Nature Conservancy’s Trees in Peril project, which uses long-term monitoring plots to help locate potentially resistant hemlocks.

Participants will learn how to establish long-term monitoring plots to assess hemlock health and identify potentially HWA resistant hemlock trees. The program will also cover the basics of hemlock ecology, how to identify HWA, and how monitoring plots support hemlock conservation and research efforts. There will be a classroom portion to the program as well as a hands-on outdoor portion where participants will help set up a monitoring plot. Participants should be prepared to spend time in cold temperatures during the outdoor portion of the program.The program is put on by CCE Columbia Greene and the New York State Hemlock Initiative.
