Four additional species, the northern myotis (Myotis septentrionalis), the Indiana myotis (M. sodalis), the hoary bat (Lasiurus cinereus), and the southern bog lemming (Synaptomys cooperi) probably are present but have not been documented. Some of the most abundant mammals are the eastern cottontail, the eastern fox squirrel, the white-footed mouse, the white-tailed deer, and the meadow vole.
Extirpated species are the common porcupine (Erethizon dorsatum), the gray wolf (Canis lupus), the red wolf (C. rufus), the black bear (Ursus americanus), the fisher (Martes pennanti), the northern river otter* (Lutra canadensis), the mountain lion (Felis concolor), the lynx (Lynx lynx), the bobcat (L. rufus), the elk (Cervus elaphus), and the bison (Bos bison).
