Hemlock Woolly Adelgid Threatens Plantations’ Natural Areas

The hemlock woolly adelgid, a non-native insect pest, was recently discovered in Cornell Plantations’ Cascadilla Gorge and Beebe Lake Natural Areas, threatening hemlock trees and the biodiversity they support. This invasive, aphid-like insect has decimated hemlock populations in the Eastern US with a nearly 100 percent mortality rate. These losses result in negative environmental changes for many animals and plants, so early detection of new infestations is crucial.Learn more about this invasive insect and what you can do on our hemlock woolly adelgid page.
