Prioritizing Eastern Hemlock (Tsuga Canadensis) For Secondary Imidacloprid Treatment Against The Invasive Hemlock Woolly Adelgid (Adelges Tsugae) In Shenandoah National Park, Katelyn Walters
Masters Theses, 2010-2019
Shenandoah National Park (SNP) contains over 20,000 eastern hemlocks (Tsuga canadensis); a foundation species in the southern Appalachian Mountains. Hemlock is shade-tolerant and retains a dense needle canopy year-round, creating a unique microclimate providing habitat for many species. The decline in eastern hemlock from hemlock woolly adelgid (Adelges tsugae; HWA) infestation has negative implications for the overall function of forest ecosystems. The effect of slope aspect and time since imidacloprid insecticide treatment on crown health change and diameter growth of eastern hemlock in SNP was quantified. Data was compared from hemlock trees located on southeastern (SE) and …
