Helping our Hemlocks: An Update on Research and Actions to Protect Hemlocks in Skaneateles

  • Wednesday, February 22, 2023, 10:00 AM - 11:00 AM

Join us for a presentation sharing research and actions focused on protecting Hemlock trees in the Skaneateles watershed and across NY State from Hemlock Woolly Adelgid (HWA), an invasive insect that kills Hemlocks. The NYS Hemlock Initiative will share research updates on HWA, including the different biocontrol options. This program will also provide an update on the independent work of both Skaneateles Lake Association and Onondaga County Soil and Water Conservation District to treat Hemlocks in high priority steep ravines in the Skaneateles watershed, on both public and private property. As a "foundation" species, hemlocks play a critical ecological role, providing many ecosystem services including protection of water quality. The Hemlock Woolly Adelgid is an insect native to Asia that lives and feeds on Hemlock trees. HWA infested trees typically die about 6-20 years after infestation. Come learn about HWA identification, management, and biological control research to find a long-term solution for hemlock conservation in New York.
