Memorial Grove Hemlocks features an excellent example of old-growth hemlock forest dominated by hemlock with yellow birch and sugar maple and exhibiting very little evidence of human disturbance. Other trees include basswood, white ash, black ash, paper birch, and balsam fir. The site provides good habitat for a variety of forest songbirds including blackburnian, and black-throated green warblers, ovenbird, solitary vireo, golden-crowned kinglet, and brown creeper. The grove was established as a memorial to four Forest Service employees who lost their lives in World War II. Memorial Grove Hemlocks is owned by the U.S. Forest Service and was designated a State Natural Area in 1996. This site is also recognized by the Forest Service as an established Research Natural Area.
