SHORELAND HABITATS 



A county-by-county description of the most significant shoreline 

 habitats and the potential impacts form OCS oil and gas development 

 are given in the following paragraphs. Although habitats in San Diego 

 have been described along with rare or endangered species that they 

 support, no attempt has been made to assess OCS-related impacts 

 because there are no plans for nearby oil and gas development. Leas- 

 ing of tracts along the San Diego coast in Sale 48 will affect these 

 areas, but more precise identification of threatened areas will have 

 to await identification of leased tracts. 



San Diego County 



1. Border Field State Park , a tract of 300 acres located near 

 the Mexican border, is the home of a rich diversity of fauna and 

 resident and migratory birds. It supports six rare plant species: 

 Agave shawii , Cereus emoryi , Cordylanthus maritimus , Dudleya attenuata , 

 Echinocactus viridescens , and Opuntia parryi var. serpentina . 



2. Buena Vista Lagoon , 220 acres, is one of the last large and 

 relatively undisturbed lagoons in Southern California. It supports 

 the following three plant communities: saltwater lagoons, coastal 

 salt marshes, and freshwater marshes. The area hosts many shorebirds. 



3. La Jolla Bay , Scripps Submarine Canyon and La Jolla Submarine 

 Canyon is one of the most studied and richest submarine canyon systems 

 in the world. Large colonies of unique phoronids and the rare yellow 

 sponge. Polymastia pachymastia . (cnly known site) occur in the system. 

 The canyon floor and walls support dozens of plant and animal species,
