Abstract

Significant mortality of eastern hemlock, Tsuga canadensis, associated with the hemlock woolly adelgid, Adelges tsugae, (HWA), has occurred in Connecticut forests since a recent introduction of the insect in 1985. Mortality associated with HWA has also occurred recently in the Delaware Water Gap (PA and NJ) and the Shenandoah National Park (NC).
