Kreosotbusch
Vegetation is dominated by the creosote bush ("Larrea tridentata"), which is widespread. The saguaro cactus ("Carnegiea gigantea") and the ocotillo ("Fouquieria splendens") are common on the bajadas, while many of the desert trees found are restricted to dry watercourses; these include paloverde ("Parkinsonia"), the desert willow ("Chilopsis linearis"), desert ironwood ("Olneya tesota"), and smoke trees ("Psorothamnus spinosus").
