Tijuana Slough National Wildlife Refuge
Tijuana Slough National Wildlife Refuge is located in the most southwestern corner of the contiguous United States. As a National Wildlife Refuge, it is administered by the U.S. Fish and Wildlife Service. It was established in 1980.
The refuge forms the northern part of the Tijuana River National Estuarine Research Reserve, one of 22 National Estuarine Research Reserves created nationwide to enhance scientific and public understanding of estuaries, and thereby contribute to improved estuarine management. It is also part of the San Diego National Wildlife Refuge Complex.Description
The slough is one of southern California's largest remaining salt marshes without a road or railroad trestle running through it. This important salt marsh is surrounded by San Diego County and Tijuana, Mexico, with a population of 4.3 million people. Within this international bioregion, the refuge maintains essential habitats for many migrating shorebirds and waterfowl along the Pacific Flyway.
Tijuana Slough provides critical habitat for the federally listed endangered California least tern, light-footed rail and least Bell's vireo, as well as the salt marsh bird's-beak, an endangered plant species. Designated as a Globally Important Bird Area by the American Bird Conservancy, over 370 species of birds have been sighted on the refuge.
The refuge's habitat and wildlife management programs focus on the recovery of endangered species through research, habitat restoration, and environmental education.
