Free Hemlock Surveys

Our most recent endeavor in protecting Michigan’s natural resources is to survey and detect Hemlock Woolly Adelgid (HWA), a parasitic insect that feeds exclusively on hemlock trees. If left untreated, infested hemlocks can die in as little as 4-10 years. This invasive species is working its way north, supposedly using the Lake Michigan shoreline as its primary avenue to expand its range. If left unchecked, Michigan’s native hemlock population could be in serious trouble.
