Hemlock Woolly Adelgid (HWA) kills hemlock trees. We are asking volunteers to search for HWA in State Parks, and other forested areas throughout the region. Check the branches of hemlock trees for round white masses at the base of needles during the fall/winter. Other signs of HWA are lack of new growth in the spring, and needle loss and discoloration. Please report positive and negative observations to iMapInvasives.org.
