About the Preserve

Who We Are

The Cosumnes River Preserve consists of over  50,000 acres of wildlife habitat and agricultural lands owned by seven land-owning Partners. The Partners include The Nature Conservancy, Bureau of Land Management, California Department of Fish & Wildlife, Sacramento County Regional Parks, Department of Water Resources, Ducks Unlimited, and the California State Lands Commission. The Preserve is centered along the Cosumnes River, its floodplains and riparian habitat. This habitat is buffered by a variety of agricultural operations. The Preserve provides numerous social, economic, and recreational benefits to local communities and to people residing in the larger Sacramento and San Joaquin areas. The habitat supports wildlife, including birds that migrate throughout the Pacific Flyway.

Mission and Vision

The Cosumnes River Preserve Partnership envisions the permanent protection of floodplains, wetlands, valley oak riparian forests, vernal pool grasslands, and compatible agricultural lands within the lower Cosumnes River watershed and the upper Sacramento-San Joaquin Delta.  The Partnership will continue to utilize inter-disciplinary programs that integrate environmental protection, restoration, and long-term land management with education, stewardship, science, and public policy strategies to sustain a dynamic mosaic of habitats that support native plant and animal species.  The Partnership will reduce potential barriers and provide opportunities so that all people may appreciate the flora and fauna of the Cosumnes River Preserve.
