Description
Background: Hemlock Woolly Adelgid (HWA, Adelges tsugae) is an invasive insect from Asia, infesting hemlock trees across the eastern United States. HWA causes defoliation and eventual mortality in hemlock species. Little control exists, but continual monitoring is necessary both nationwide and in our own backyard. Methods: As an observational study, we will determine where hemlock groves exist on Liberty University’s campus. Upon arrival to a tree, we will determine infestation using previous studies and overall canopy loss using a light meter. Results: Unfortunately, we expect 90% of hemlock trees to be infested with HWA. We expect to find significant needle loss across all hemlock populations. Conclusions: At this point in time, little control methods exist for HWA. As this infestation continues to spread, the greatest thing we can do is monitor where, and how intensely, the insect manifests. A comprehensive record of where ecologists can find HWA, even in island populations, is vital for conservation efforts.
