Abstract :	In the last two decades, substantial declines in eastern hemlock (Tsuga canadensis) have been observed throughout the eastern United States. Widespread hemlock defoliation has largely been attributed to the hemlock woolly adelgid (Adelges tsuga; HWA), an exotic aphid-like insect that is native to Asia. Resource managers expect the adelgid to continue to spread and consequently the entire hemlock forest ecosystem may be threatened. The impact of the removal of this important climax forest species on the ecology of Appalachian forests is poorly understood, but has the potential for significant disturbance to biotic communities by changing the energy inputs, micro-climatic environments, and physical habitat structure available to other vegetation, birds, mammals and aquatic communities. The current study addresses the aquatic and GIS modeling components of a larger collaborative initiative involving investigators from the National Park Service, and Pennsylvania State University.
