Healthy Hemlocks

During spring break from Penn State I visited my family in Maine. Taking a hike in the Thorncrag Bird Sanctuary in Lewiston I came across this lovely stand of healthy hemlock. In most of Pennsylvania the hemlock woolly adelgid has decimated the hemlock forests. I had forgotten how attractive a stand of healthy hemlock trees looks. No wonder it was made the state tree of Pennsylvania. This just shows the danger of invasive species and pests.
