Yuma Desert
The Yuma Desert is a lower-elevation section of the Sonoran Desert in the southwestern United States and the northwest of Mexico. It lies in the Salton basin. The desert contains areas of sparse vegetation and has notable areas of sand dunes. With an average rainfall less than 8 inches (200 mm) each year, this is among the harshest deserts in North America. Human presence is sparse throughout, the largest city being Yuma, Arizona, on the Colorado River and the border of California.
Overview
The desert includes the lower-elevation parts of the southwestern corner of Arizona, extending west to the Colorado River. On the other side of the river, in California, is the Colorado Desert region of the Sonoran Desert, also referred to as the Low Desert. Though the two regions are separated only by the Colorado River, there are numerous species of plant and animals that live only on one side or the other, such as saguaro cactus, which occurs only east of the river. The Yuma Desert also includes the sandy plains of western Sonora, going all the way to the head of the Gulf of California, then an inland strip reaching into the central Sonoran interior. The most significant river in this desert is the Gila River of Arizona. Organ Pipe Cactus National Monument is located in this desert, as are the Kofa National Wildlife Refuge and Cabeza Prieta National Wildlife Refuge.
To the south of Arizona's Yuma Desert in northern Mexico, is the Pinacate volcanic field and biosphere reserve, part of the Gran Desierto de Altar, and is the southern extension of the Yuma Desert. It is on the northwestern foothills of Mexico's Sierra Madre Occidental, the western mountain cordillera.
Flora

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).
