The New York State Department of Environmental Conservation (DEC) and partners issued an update about ongoing efforts to limit the spread of the invasive pest Hemlock Wooly Adelgid (HWA) on Forest Preserve lands in Washington County as part of an ongoing, multi-year initiative. DEC confirmed the HWA infestation in August 2020, and began treatment in October on affected hemlock trees in the Glen Island Campground on the shores of Lake George.
Treatment began Oct. 6, 2020 along the shorelines of Lake George and was conducted over a four-week period by DEC staff. DEC prioritized the infestation at Paradise Bay due to the site’s size and levels of infestation. Crews treated 2,374 trees with insecticide on 138 acres of Paradise Bay and injected insecticides directly into the trunks of 80 trees close to sensitive areas. In addition, the New York State Hemlock Initiative released 620 Laricobius beetles, a biological control for HWA, in the treatment area to feed on HWA.
