Hill Slough Wildlife Area


Hill Slough Wildlife Area is approximately 1,700 acres of salt tidal marsh, managed marshes, sloughs and upland grassland. The area supports a wide variety of waterfowl, including pintail, mallard, shoveler, green-winged teal, and wigeon. Raptors such as northern harriers, white-tailed kites, kestrels, and red-tailed hawks can be seen hunting the grasslands. Raccoons, jackrabbits, and voles make their homes here and may provide a meal for the coyotes that hunt and live in the wildlife area.

Area History

Hill Slough, a relatively small wildlife area, was originally acquired to meet mandates of the state's Suisun Marsh Preservation Act of 1977. The first acquisition of 1,100 acres was in 1978. The property was designated as a wildlife area by the Fish and Game Commission in 1979. Subsequent acquisitions and donations have expanded the site.
