Hemlock Woolly Adelgids Found in Tompkins County

They are native to Japan. Aside from aesthetic qualities, hemlocks play important roles in the ecology of local gorges. They moderate stream temperatures in the summer creating a habitat that is favorable to native brook trout as well as wildlife and plants that rely on cooler microclimates. They also play a role in maintaining water quality by stabilizing steep gorge slopes and buffering sediment runoff. Read more...
