Detailed Description:

One of only 28 Reserves in the US, the Tijuana River National Estuarine Research Reserve protects, studies and educates about the Tijuana River Estuary. Border Field State Park was established as a state park in 1971 as part of President Richard Nixon’s Legacy of Parks program. The Tijuana National Wildlife Refuge was established in 1980 preserving the northern part of the estuary. Voters wanted the area to be given to developers to create an upscale marina throughout the early 1980s. Despite this opposition, the area officially became a National Estuarine Research Reserve by the Department of Commerce in 1982. The area is of such interest, it was named by the United Nations as a Wetland of International Importance which means this Reserve is only one of 2,127 picked in the world!
