Crow Island State Game Area lies within the Saginaw Bay lake plain, formerly characterized by swamp forest, wet-mesic prairie and emergent marshes. It is presently a complex of emergent wetlands, managed wetland impoundments and agricultural uplands that provide habitat for a wide variety of migratory birds (both game and non-game) as well as associated invertebrate, reptiles and mammalian wildlife.
Crow Island SGA spans portions of Saginaw and Bay Counties along the lower Saginaw River in east-central Lower Michigan. There are presently 3,489 acres included in state ownership.
Through habitat management efforts, native mammals, herpetiles and a variety of game and non-game birds also benefit. In addition to providing for the habitat needs of various wildlife species, Crow Island is primarily managed to provide hunting, trapping and wildlife viewing opportunities to the public.
