Look for silver tags on some Eastern hemlock trees. Tagged trees are treated with a systemic insecticide to keep these trees alive after being infected by the Invasive Hemlock Woolly Adelgid (HWA), which has decimated hemlocks throughout the Northeastern U.S. HWA has been detected on hemlock trees within nearly all of our natural areas and our staff routinely treat over 3,000 trees every five to seven years. Milder winters brought about by climate change have enabled hemlock woolly adelgid to expand its range northward.
Learn more about our effort to control the hemlock woolly adelgid here.
Big tree alert: Look for exceptionally large hemlock and basswood trees, estimated to be over 200 years old.
