The San Luis National Wildlife Refuge encompasses over 26,800 acres of wetlands, riparian forests, native grasslands, and vernal pools. A thriving population of the endemic tule elk is showcased by 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 Refuge is a major wintering ground and migratory stopover point for large concentrations of waterfowl, shorebirds, and other waterbirds. Large flocks of green-winged teal, northern shoveler, mallard, gadwall, wigeon, cinnamon teal, northern pintail, ring-necked duck, canvasback, ruddy duck, and snow, Ross’, and white-fronted geese swarm over the mosaic of seasonal and permanent wetlands that comprise a quarter of the Refuge. Waterfowl generally remain until late March before beginning their journey north to breeding areas. However, some mallard, gadwall, and cinnamon teal stay, breed, and raise young on the Refuge.
