Why it Matters: This project focuses on four specific geographies in Michigan’s Northcentral Tillplain region: the River Raisin headwaters, the Grand River headwaters, the Paw Paw River headwaters, and the Newaygo Plains. Each of these areas supports some of Michigan’s finest and rarest examples of fens, prairies, oak savannas and associated habitats. These habitats house a variety of rare and endangered  plant, animal, and insect species such as the Mitchell's Satyr butterfly, Massasauga rattlesnake, and Karner blue butterfly. These fens act as natural water filters; offer hunting by permit and other recreational opportunities.
