Hike to Protect Beech Trees

September 20, 2022 @ 1:00 pm - 3:00 pm

Enjoy a guided walk in the woods, and learn to recognize and report the newest threat to American Beech Trees: Beech Leaf Disease (BLD). Tug Hill Tomorrow Land Trust (THTLT), the St. Lawrence-Eastern Lake Ontario Partnership for Regional Invasive Species Management (SLELO PRISM), and NYS DEC Forest Health Specialist Maria MoskaLee will lead the program.

BLD is spreading rapidly across the Northeastern U.S. and Canada, affecting and killing both native and ornamental beech tree species. Associated with a nematode whose presence is thought to cause leaf disfiguration including striping and curling. Young trees can die in less than five years after the first signs of damage appear. BLD has only been discovered in recent years. In 2022, it has been found in 15 new counties in New York, for a total of 35 infected counties. It was recently found in Oswego County in the SLELO region, and nearby on the southwestern edge of the Adirondacks.
