Eastern Hemlock Facts
Eastern Hemlock (Tsuga canadensis) is the state tree of Pennsylvania. Its wood is brittle and difficult to work with, but still is harvested to an extent. It is currently being decimated by the Hemlock Woolly Adelgid, which is a non-native insect from East Asia. Hemlocks are extremely long living, they can thrive more than 800 years. They are an important food source for songbirds and larger mammals use their dense stands for cover. Hemlock bark was once a source of tannin for the leather industry. You can still hike amongst old growth in many of Pennsylvania’s State Parks. We recommended Cook Forest State Park.
