Abstract

We present a synthesis of current knowledge and information of hemlock woolly adelgid (HWA, Adelges tsugae Annand) impact on hemlock forests and conceptual framework of restoring damaged hemlock stands by HWA infestation. Native to Asia, HWA has been thriving in the eastern United States since the early 1950s and has become a serious pathological agent of both eastern hemlock (Tsuga canadensis (L.) Carriere) and Carolina hemlock (Tsuga caroliniana Engelm.) ever since.
