Abstract

Eastern hemlock, Tsuga Canadensis (L.) Carriere, and Carolina hemlock, Tsuga caroliniana Engelmann, provide unique habitat that is threatended by the invasive hemlock woolly adelgid, Adelges tsugae Annand, which arrived in Georgia in 2003. In an attempt to conserve a portion of the mature hemlocks in north Georgia, the USDA Forest Service created over 100 Hemlock Conservation Areas throughout the Chattahoochee National Forest and designated them to receive chemical and/or biological control.
