The Hemlock Woolly Adelgid (HWA) Action Team is a diverse group of scientists, land managers, and others who are pooling their expertise and resources to combat the immediate and critical threat posed by the Hemlock Woolly Adelgid in the Southern Appalachians. The action team has an oversight committee to coordinate all activities, an education outreach / public awareness program, and groups addressing different management needs and foci. Understanding the IssueHemlock Woolly Adelgid (Adeleges tsugae) is native to Asia where it is not a problem to native hemlocks. It was introduced to the United States in the 1920s to the Pacific Northwest, and in the early 1950s to the Washington DC and Richmond, Virginia areas. It lacks natural enemies in North America, so it has since spread throughout the eastern United States creating an extreme amount of damage to natural stands of hemlock, specifically eastern hemlock (Tsuga canadensis) and Carolina hemlock (Tsuga caroliniana). See the Hemlock Woolly Adelgid Fact Sheet (.pdf) to learn about this threat, what land managers are doing to address it, and how you can help. How Can I HelpHow to Control Hemlock Woolly
