Description: Hemlock woolly adelgid (HWA) is a non-native invasive pest that impacts eastern hemlock and Carolina hemlock. HWA was first reported in the 1950's in the northeastern U.S., and has now spread to the southern Appalachian region of northern Georgia, western North Carolina, and southern Virginia. Without control, hemlocks typically die within 5 to 7 years after infestation. Unfortunately, neither natural predators nor host resistance have been able to stop the spread of HWA. A long-term comprehensive research program is underway at the Coweeta Hydrological Lab to address four key elements of the HWA problem: 1. Evaluating control strategies to reduce or eliminate the spread of HWA, 2. Understanding the impacts of hemlock mortality on ecosystem resources, 3. Developing monitoring techniques that determine and predict HWA spread, and 4. Developing and evaluating restoration techniques to mitigate the impacts of hemlock mortality on ecosystem resources.
