The Impacts of Hemlock Woolly Adelgid on Army Installations
Introduction
Threat
The Hemlock Woolly Adelgid (Adelges tsugae, HWA) is an invasive insect native to East Asia which is now spreading across the Northeast affecting training areas and forests on military installations. HWA kills Eastern Hemlock (Tsuga canadensis) within 4-10 years, by feeding on the nutrients at the base of the needles during the winter (NYS DEC). The Eastern Hemlock is a foundational tree species in the northeast United States that plays a crucial ecological role in supporting wildlife habitats (Biological Control of Hemlock Woolly Adelgid 2024)
