The LAX Dunes (also known as The Los Angeles/El Segundo Dunes, which lie between the west end of the Los Angeles International Airport (LAX) and the Pacific Ocean, are the largest remaining representation of coastal dune community within Southern California. The 302-acre Dune site is owned and managed by Los Angeles World Airports (LAWA). The site provides habitat for over 900 species, some of which cannot be found anywhere else on Earth. It is home to the beautiful and delicate federally endangered El Segundo Blue Butterfly, and other rare plant, animal, and insect species.
The El Segundo blue butterfly is endemic to coastal sand dunes that contain suitable conditions for the early stages, larval food plants, adult nectar sources, and adult feeding, perching, and courtship areas. Urban development and invasion by exotic species have resulted in a significant loss and modification of the species’ habitat. Protection and management of existing and potential habitat, removal of exotic vegetation, and reduction of other threats to the species and/or its habitat is needed.
