About San Luis National Wildlife Refuge

The San Luis National Wildlife Refuge encompasses over 26,800 acres of wetlands, riparian woodlands, native grasslands, and vernal pools. A thriving population of endemic tule elk is showcased on one of three auto tour routes. The refuge is host to significant assemblages of birds, mammals, reptiles, amphibians, fish, insects, and plants; some of which, such as the California tiger salamander, the long-horned fairy shrimp, and San Joaquin kit fox, are endangered species.The San Luis National Wildlife Refuge was established in 1967 under the Migratory Bird Conservation Act. The first refuge parcel was purchased with federal Duck Stamp funds to serve as inviolate sanctuary for migratory waterfowl. The refuge has grown over the years and today it is comprised of six contiguous units: San Luis, East Bear Creek, West Bear Creek, Freitas, Blue Goose, and Kesterson. The eastern portion of the refuge is bisected by the San Joaquin River. The refuge is a major wintering ground and migratory stopover point for large concentrations of waterfowl, shorebirds, and other waterbirds. From autumn through spring, the wetlands on the refuge come alive as large numbers of migrating waterfowl, shorebirds, and wading birds arrive in the San Joaquin Valley. Here, the wetlands provide plentiful food and shelter, and a critical wintering area along the Pacific Flyway migration route. The wetlands also support a wide variety of other animals, including mammals, amphibians, reptiles, and insects. Waterfowl generally remain until late March before beginning their journey back north to breeding areas; however, some mallard, gadwall, and cinnamon teal remain in the area to nest and raise young.Shorebirds, including species of sandpipers and plovers can be found in the tens of thousands from autumn through spring. Large flocks of dunlin, long-billed dowitchers, least sandpipers, and western sandpipers can be seen feeding in shallow seasonal wetlands. Flocks of long-billed curlews are found using
