Hemlock Woolly Adelgid Confirmed in ANF
Tests by both the US and Pennsylvania departments of agriculture have confirmed that the insect has infested trees within a proposed wilderness area.
The Hemlock woolly adelgid is a small insect native to East Asia that feeds by sucking sap from hemlock trees. In eastern North America, it is a destructive pest that poses a major threat to the Eastern hemlock.
Friends of Allegheny Wilderness will be organizing a volunteer outing in the near future to hike further into the area in an attempt to ascertain the extent of the infestation there.
