Just weeks after the invasive Emerald Ash Borer was discovered for the first time in the Adirondack Park, another invasive species has been found within the boundaries of the Blue Line: Hemlock Woolly Adelgid (HWA). First recorded in the Adirondack Park in 2017 on Prospect Mountain in Lake George, HWA was recently found on Glen Island, about 12 miles north of Prospect Mountain. An insect native to East Asia, HWA infests Northeastern Hemlocks and can wipe out stands in a matter of years. Hemlocks are vital to protecting streams banks from erosion and create habitat preferred by many Northeastern amphibians. As such, HWA represents a critical threat to the health of the Adirondack Park’s ecosystem.
