Tijuana Slough NWRTJ Slough 25th Anniversary Logo

Home to many endangered birds and one endangered plant, this beautiful 1051 acre wetland where the Tijuana River meets the sea is southern California's only coastal lagoon not bisected by roads and rail lines. The refuge is also part of the Tijuana River National Estuarine Research Reserve, one of only 26 NERRs in the entire U.S.

Over 370 species of birds have been recorded on the refuge and in the adjacent river valley. The endangered California Least Tern, Least Bell's Vireo, California Brown Pelican, Light-footed Clapper Rail and an endangered plant, Salt Marsh Bird's Beak can all be found on the refuge. The Western Snowy Plover, a threatened species, is a year round resident and nests on refuge beaches.

Tijuana Slough's habitats include open water, tidal salt marsh, beach dune, riparian, vernal pool and upland surrounded by residential neighborhoods.
