Background: California's largest stand of valley oak riparian forest borders the largest undamned river. A trail passes a young, restored riparian forest, then moves to reconstructed marshes that attract wintering tundra swans, sandhill cranes, and scores of ducks. Long-billed curlews and other shorebirds forage in pastures and wetlands. River otters, beavers, and muskrats swim in cattail-lined sloughs, passing green herons and wood ducks. Riverside willows, blackberries, and wild grapes give way to an oak-studded savannah, areas favored by black-tailed deer, Nutthall's woodpeckers, and western bluebirds. The tallest trees bear the spring nests of Swainson's hawks.

Site Notes: The Cosumnes River is the largest free-flowing Sierran river flowing into California's Great Central Valley. Its floodplain is closer to a natural state than any other in the region.

The Cosumnes River supports a run of Chinook salmon. Mammals include river ottern beaver & muskrat. The rare giant garter snake makes its home in the marshes and adjacent uplands. The riparian forest bordering the river is home to raccoon, black-tailed mule deer, mink and numerous species of songbirds. More than 250 species of birds have been recorded on the Preserve, including several nesting pairs of the threatened Swainson's hawk. Marshes support impressive numbers of greater and lesser sandhill cranes, Ross', white-fronted and Canada geese, tundra swans, and numerous species of ducks. Birds such as great blue herons, black-crowned night herons and white-tailed kites are common.

The Cosumnes River Preserve benefits from programs established by the Bureau of Reclamation's Central Valley Project Conservation Program (CVPCP) and the Central Valley Project Improvement Act (CVPIA) Habitat Restoration Program.
