Hemlock Woolly Adelgid Walk, Talk & Survey February 5, 202610:00 am - 12:00 pm « 2026 Winter Environment Conference 2026 Tug Hil Bird Quest » Join us for a guided Hemlock Woolly Adelgid (HWA) Walk and tree survey at the Trenton Greenbelt Trails, 7905 Wood Rd, Holland Patent, NY on Thursday, February 5th from 10:00 am to Noon. We’ll take an easy walk, stopping at points along the way with THTLT and SLELO PRISM (St. Lawrence-Eastern Lake Ontario Partnership for Regional Invasive Species Management) staff to learn how to recognize Eastern Hemlock trees, examine the trees, and report observations using their smartphone through a free mobile application called iMapInvasives (a community science tool). Registration is required. There is no charge for attendance or parking. You may need snowshoes. HWA is an invasive insect that kills hemlock trees. The Eastern Hemlock is a key tree species found throughout Tug Hill that provides many benefits for people and nature. Detecting the presence of HWA early on provides enough time to protect infested trees and helps to stop the spread to new areas. It is easier to survey for HWA in colder months, as the tiny insects form a woolly-looking ball of insulation around themselves that makes them more visible. The walk will still take place in light rain or snow. We will monitor weather right up to the morning of our walk. If weather should turn severe and the event require rescheduling, all registrants will be contacted by phone and email. This is the second of three HWA outings to be hosted by THTLT and SLELO PRISM through March of 2026. The next outing will take place on Thursday, March 5th at Forest Park in Camden.
