Habitat and Wildlife

“The Grass River Natural Area covers more than 1,443 acres which include a wide diversity of natural habitats: open fields, upland forests, marshes, swamps, creeks and rivers. More than 400 species of plants, 65 species of birds, 35 species of fish, and 33 reptiles and amphibians have been identified. Grass River is a 2.5 mile waterway connecting Lake Bellaire and Clam Lake, forming part of Antrim County’s “Chain of Lakes.”

The Grass River flows over a bed of sandy glacial till and is clear most of the year. Heavy motorboat traffic does erode the banks sometimes clouding the water in summer. PLEASE observe the NO WAKE signs when you travel on the river.
