Eastern Hemlock (Tsuga canadensis) [ Trees > Conifers > Hemlocks . . . ] Forest Type: N. Hardwood, App. Cove The Woolly Adelgid, an Asian insect, currently threatens the eastern Hemlock throughout much of its range. Attempts to control the woolly adelgid have not been successful, and some experts predict a disaster on the scale of the chestnut blight that wiped out the American chestnut. The adelgid can be seen, covered with white "wool," at the needle bases of infected trees (illustration to the right).
