Fish and Wildlife Service, Texas.
The Lower Rio Grande Valley National Wildlife Refuge was established in 1979 with a management priority to protect biodiversity. As a wildlife corridor, the refuge follows the Rio Grande along the last 275 river miles. It connects isolated tracts of land managed by private landowners, non-profit organizations, the State of Texas, and two other National Wildlife Refuges: Laguna Atascosa and Santa Ana.
Headquarters for Lower Rio Grande Valley NWR and the South Texas NWR Complex is at the Santa Ana National Wildlife Refuge Visitor Center, 7 miles south of Alamo on FM 907 and 1/4 mile east on U.S. Highway 281.
