With 88,000 acres of land, bays and sloughs, the Suisun Marsh is significant: it is the largest contiguous estuarine marsh in the entire United States. Grizzly Island Wildlife Area is approximately 12,900 acres of this prime habitat and the complex is a patchwork of 10 distinct land parcels, many of which are not connected and are surrounded by private land. Units include Grizzly Island, Crescent, Joice Island, Island Slough, Gold Hills, West Family, Goodyear Slough, and Grey Goose. They offer a variety of recreation opportunities and act as a vital buffer against further marsh development. The complex combines natural tidal wetlands and artificially diked marshes. Each habitat attracts a special kind of wildlife. Pass some hours along the bay or on the graveled foot trails at Peytonia Slough. Experience the renewing rhythm of the tides, the changing complexion of marsh life. Some animals, like the California clapper rail and Suisun shrew, live exclusively in these tidal wetlands. Rare, threatened and endangered species include the salt marsh harvest mouse, peregrine falcon, California Ridgway's rail, California black rail, bald eagle, Suisun aster, and soft-haired birds beak. CDFW staff manage extensive waterways and pumps to create more than 12,000 acres of seasonal ponds. Plants like alkali bulrush and fat-hen are encouraged. This carefully managed combination of high nutrient food and resting ponds sustains more than 100,000 waterfowl that winter at Grizzly Island each year.
