Background: The Grizzly Island Wildlife Area Complex is located in the Suisun Marsh, the largest continuous estuarine marsh in the lower forty-eight states. Salt marshes, tidal flats, seasonal ponds, and uplands shelter 250,00 wintering waterfowl, thousands of shorebirds, dozens of songbird species, and seven protected species, including endangered salt marsh harvest mice. A large population of river otters swim in the abundant sloughs. Riparian vegetation hides several heron species, clapper rails, and elusive black rails. Some species, such as the Suisun aster, shrew and Suisun sparrow, are found nowhere else on earth. Managed ponds host cinnamon teal, northern pintails, and American white pelicans, some remain to breed. Songbirds include marsh wrens, common yellowthroats, and many others. Northern harriers, white-tailed kites, short-eared owls, golden eagles, and other birds of prey hunt upland fields that also sustain tule elk, a species native only to California.
Interpretive panels at the headquarters only.

The Habitat: Managed wetlands (fresh, saline, and brackish), ponds, and uplands for wildlife use, hunting, fishing, and other wildlife dependant activities such as wildlife viewing, nature study, and education.

The Experience: Due to Suisun Marsh's large size and abundant wildlife, this is an area of great ecological value.

Wildlife and Where to Find It: Parking lots and open terrain. There are not any improved trails.

Viewing Tips: More than 230 bird species. Peak viewing month is February (once opened after waterfowl hunting season). High probability of seeing wading birds year-round. Birds of prey are seen year-round, particularly in fall and winter. Waterfowl and shorebirds are common in winter, with many summer broods. Look for songbirds in winter and small and aquatic mammals year-round. Excellent car viewing. Seventy-five miles of levees open February through July. Always call for information on seasonal closures.

Site Notes: Although GIWA Complex is a major wildlife area for hunting and fishing opportunities, there are also opportunities for other wildlife dependant activities.
