Why Are Eastern Hemlock Trees Important?Eastern hemlocks (Tsuga canadensis) are one of the longest-lived tree species and can live up to 800 years in eastern North America. These evergreens typically grow along streams and on steep slopes where few other trees can grow, which helps maintain erosion control and water quality. Eastern hemlocks also have a very dense canopy, which is ideal habitat for birds and other wildlife. The shade they provide along streams and rivers is essential for many cold water fi sh species, such as brook trout.

Where is the Hemlock Woolly Adelgid Found?The presence of the hemlock woolly adelgid was confi rmed in the lower Hudson Valley in the 1980s. Since then, they have spread north into the Catskills and the Capital Region. More recently, the hemlock woolly adelgid has begun to invade the Finger Lakes area.

These insects are spreading throughout New York State,

where they have the potential to devastate our hemlock population.

We need your help in identifying and reporting infestations in New York.
