Excerpt from Proceedings of the Southern Appalachian Biological Control Initiative Workshop: Asheville, North Carolina, September 26 and 27, 1996 Currently the natural heritage of southern Appalachia is threatened by a number of accidentally introduced exotic species. Native dogwood is being attacked by a disease known as dogwood anthracnose. The native American chestnut is falling victim to another disease - chestnut blight. An insect, balsam woolly adelgid, threatens Frasier fir. Hemlock woolly adelgid, another insect, is attacking native hemlock. The effects of these and other exotic pests on the ecosystem are dramatic. Another example of devastation effected by exotic species is the defoliation of oak trees by the gypsy moth, introduced by an entrepreneur who was seeking to establish a silk business in the northeast United States. The gypsy moth, a European pest, migrated to northern Virginia from the New England States. It is expected to be in northern Alabama by the year 2010. Because oak trees are valuable for timber as well as tourism (they provide much of the fall color which pe0p1e travel to southern Appalachia to view) gypsy moth has a major effect on the economics of the region.
