Grasslands Wildlife Management Area lies within the San Joaquin River basin and supports the largest remaining block of wetlands in the Central Valley, containing 70,000 acres of private wetlands and associated, and surrounding 53,000 acres of state and federal lands. Perpetual conservation easements on private lands have been purchased by the Service. Land management activities are the responsibility of the landowners, not the Service. These wetlands and associated grasslands, complemented by two national wildlife refuges and four state wildlife areas, comprise over 160,000 acres and are collectively known as the Grasslands Ecological Area. This area is extremely important to Pacific Flyway populations of 19 duck species and 6 goose species. The Grasslands Ecological Area has been officially recognized as an integral unit of the Western Hemispheric Shorebird Reserve Network. Large concentrations of migratory waterfowl, wading birds, and shorebirds are common and easily observed during late winter and early spring.
The public is not permitted on the Grasslands Wildlife Management Area, as the Service did not acquire public use rights. It can be viewed from adjacent public roads, primarily Santa Fe Grade Road, which bisects the north and south Grasslands in a northwest-southeast direction, north and south of Los Banos.
