The area contains a number of important biological communities. Native plant communities include coastal sage scrub, California Annual Grassland, and Coastal Dune Scrub species; however, most native plants have been eliminated from within the city limits to make way for development. Also native to the region is the endangered Ventura Marsh Milkvetch, with the last self-sustaining population in Oxnard being at the center of a housing development.
