One of the best remaining examples of a coastal-strand environment in Southern California, the Coal Oil Point Natural Reserve protects a wide variety of shoreline and estuarine habitats. Largely undisturbed coastal dunes support a rich assemblage of dune vegetation, while older and more stable backdunes are covered with southern coastal scrub habitat. In the heart of the reserve, Devereux Slough is a seasonally flooded tidal lagoon that dries out in the summer to form salt flats and hypersaline ponds and channels. A variety of intertidal habitats occur along the sandy beach and the large rocky reef at the point.
