The Bolsa Chica Wetlands falls under the wetland ecosystem, and on a spatial scale is considered to be a more localized scale, because it focuses more on the wetlands that span over a particular plot of land. Officially, there is a conservancy that protects about 1,247 acres of it, making it the largest protected wetland in Southern California's history.

The reserve's designated boundaries span from Warner Avenue (north), to Seapoint Ave (south), and also from Pacific Coast Highway (west) to residential areas (east). However, the ecosystem also reaches unprotected areas, parts of the wetland that are not completely protected by legislation. It is also located across the street from the Bolsa Chica State Beach.
