Hemlock Wooly Adelgid
The Eastern Hemlock is currently under attack by an introduced species, known as the Hemlock Wooly Adelgid. In some areas of the country, this adelgid has virtually decimated the Hemlock population. In the Great Smoky Mountains National Park, there is a large scale effort underway to protect the hemlocks from this invasion, and its showing success.
