ADIRONDACKS—Beech leaf disease is in the Adirondacks, and scientists need help gathering data on the newly emerging forest pest. To teach community scientists how to identify and report beech leaf disease, the Adirondack Park Invasive Plant Program will host a free webinar from 10 to 11:30 a.m. on Thursday, Sept. 15, called “Forest Pest Hunters: Surveying for Beech Leaf Disease.”
Beech leaf disease was first detected in Ohio in 2012 and in New York state in 2018. In 2022, the state Department of Environmental Conservation confirmed the presence of beech leaf disease in over 30 counties in New York including Herkimer County, the first documented infestation in the Adirondack region. Beech leaf disease can kill mature beech trees in six to 10 years, while young trees can be killed in as little as two to three years.
