Eastern Hemlock on the ropes from invasive species http://apocadocs.com/s.pl?1204667456
"Eastern hemlock (Tsuga canadensis) is an aesthetically and ecologically important species of tree found from eastern Canada to the Great Lakes states and south along the entire Appalachian mountain range. Since the hemlock tends to grow alongside streams, it plays an important role in regulating water temperature, and its loss could affect the many species of fish and insect life that inhabit mountain streams.
The tree is threatened by the prolific spread of an exotic insect known as the hemlock wooly adelgid (Adelges tsugae), which kills the trees in as few as four years. In the past decade, the hemlock wooly adelgid has infested more than 50 percent of the eastern portion of the hemlock's range, and the number is expected to grow because the adelgid, an introduced species from Asia, has no natural predators in North America."
