Location: The Cosumnes River Preserve consists of approximately 45,859 acres of wildlife and agricultural lands owned by seven land-owning partners (The Nature Conservancy, Bureau of Land Management, California Department of Fish and Game, Sacramento County, Department of Water Resources, Ducks Unlimited, and the California State Lands Commission). The Preserve spans Sacramento County and the northern part of San Joaquin County.

Purpose of Acquisition: For the permanent protection of a continuous riparian corridor extending from the Cosumnes headwaters to the Delta.

Description*: Management will focus on protecting, maintaining, and restoring the native vegetative communities, especially the valley oak riparian forest and freshwater seasonal wetlands, and the native species that depend on them. Wildlife compatible opportunities for public uses within the preserve include: hiking, paddling, boating, hunting, fishing, wildlife viewing/photography, research and volunteering.

Environmental Review Process
