Generally, on islands greater than 3 km2, however, the vegetation is essentially the same as on the adjacent mainland (Cody et al. 1983). Therefore, all islands within the Gulf of California, with the exception of the Isla Encantada Archipelago, lie within the Central Gulf Coast Region (fig.

It is edged to the west by a small southern section of the Vizcaíno Desert and the Magdalena Plain. ), Palo Blanco (Lysiloma candida), Pitahaya Agria (Stenocereus gummosus), Organ Pipe Cactus (Stenocereus thurberi), Palo Adán (Fouquieria diguetii), Little-Leaf Palo Verde (Cercidium microphyllum), and Cardón (Pachycereus pringlei). Palm-lined oases (fig. 12) are characteristic of some of the deeper canyons and arroyos in these volcanic badlands, and there the dominant species are the Mexican Fan Palm (Washingtonia robusta) and Palma Palmía (Brahea brandegeei).

These form an extensive range of mountains, approximately 80 km long, bordered by the Río Colorado flood plain on the east and Laguna Salada on the west. This poorly explored mountain range harbors a depauperate, saxicolous herpetofauna containing the endemic Sierra los Cucapás Collared Lizard (Crotaphytus grismeri), Northern Chuckwalla (Sauromalus obesus), Speckled Rattlesnake (Crotalus mitchellii), and perhaps others (McGuire 1994). In westcentral Baja California, two closely situated mountain ranges, the Sierra Vizcaíno and the Sierra Santa Clara, define the Vizcaíno Peninsula.
