U.S. Forest Service officials in Raleigh, N.C., will use a helicopter, explosives, duct tape and chemicals to save the Joyce Kilmer Memorial Forest from the infestation of the woolly adelgid, a pest that has been killing hemlock trees in the vicinity. Crews will use explosives to remove dead hemlock trees. This method will help maintain the forest's natural appearance because it leaves behind a jagged tree stump. Officials will also scour the forest for remaining healthy hemlock trees from a helicopter and then administer chemicals to give them temporary protection from invasion.
