Birds landing in a marsh

The Sonny Bono Salton Sea National Wildlife Refuge was established in 1930 by executive order as a breeding ground for birds and wild animals. Primary objectives on the Refuge include endangered species production and maintenance, sensitive species production and maintenance, wintering waterfowl maintenance, and other migratory bird management. Refuge habitats are intensively managed.

    More Elk

    The white-tailed deer of the Wichita Mountains Wildlife Refuge are from original native stock that survived the early settlement years of exploitation and overhunting. In 1901, when the area became protected, the remnant deer population rapidly expanded. In 1961, the peak population hit 2,987. Today, the minimum objective population level is 450.
