Hemlock Woolly Adelgid

The Hemlock Woolly Adelgid is a pervasive invasive insect that attacks Eastern Hemlock, resulting in significant tree decline and mortality. Eastern Hemlocks are very important ecologically, as they grow in a variety of locations and provide benefits to many species, including over 120 vertebrates that are known to make use of mature hemlock stands. Public education is a key step towards stopping the spread of the adelgid and protecting our hemlocks. To learn more about this pest and what can be done, check out the resources below.
