The SLELO region is no longer the only region in NYS to have not found HWA.
While conducting early detection searches for hemlock woolly adelgid over the last several weeks, the SLELO Early Detection Team, Robert Smith and Brittney Rogers, have now observed three separate populations of hemlock woolly adelgid (HWA)in southwest Oswego county. Photographs from each site were confirmed to be HWA by Mark Whitmore, a Forest Entomologist with the Department of Natural Resources at Cornell University. This marks the first confirmed observations of HWA within the SLELO PRISM region- our region encompasses Oneida, Oswego, Jefferson, Lewis, and St. Lawrence counties.
Responding to HWA in SLELO
Experts have suggested that the more likely area for HWA to spread in the SLELO region is along the eastern Lake Ontario shoreline because of the moderated temperatures adjacent to the Lake. Landowners and land managers in Oswego county and throughout the eastern Lake Ontario region are encouraged to check their hemlock trees for signs of hemlock woolly adelgid. For those participating in hemlock woolly adelgid survey efforts, hemlock stands located along the eastern Lake Ontario shoreline should take survey priority.
Signs to look for include: lack of bright green foliage on the tips of hemlock branches in the spring, needle loss and dead branches within the tree crown, and the presence of white woolly masses in addition to black insects with white fringe, both of which will be nestled along hemlock branches where the needles connect to twigs.
If you think you have found HWA in the SLELO region, be sure to note the location of the observation, take clear photos of the infestation and email the information to the SLELO PRISM Terrestrial Coordinator, Robert Smith at firstname.lastname@example.org or contact the NYS DEC Forest Pest Hotline at 1-866-640-0652 or report the observation via NYiMapInvasives.org.
