The North American Deserts includes all the deserts located on the continent. It is also the term for a large U.S. Level 1 ecoregion (EPA)[1] of the North American Cordillera, in the Deserts and xeric shrublands biome (WWF). The continent's deserts are largely between the Rocky Mountains and Sierra Madre Oriental on the east, and the rain shadow creating Sierra Nevada, Transverse, and Peninsular Ranges on the west. The North American xeric region of over 95,751 sq mi (247,990 km2) includes: 3 major deserts; numerous smaller deserts; and large non-desert arid regions; in the western United States and in northeast, central, and northwest Mexico.

Western arid regions of North America[edit]

The separately defined western arid regions of North America are continental regions of aridity based on available water in addition to rain shadow diminished rainfall [8] and which have many non-desert shrub-steppe (EPA) and xeric shrublands (WWF) in addition to desert ecosystems and ecoregions. This large arid region of 190,000 sq mi (490,000 km2) includes: deserts, such as the Great Basin Desert and Sonoran Desert; and the non-desert arid region areas (with greater than 10 inches annual precipitation) in the Great Basin arid region, Colorado Plateau, Mexican Plateau, and others. This arid region extends from the top of the North American Desert in Washington and Idaho southward into Mexico in the Trans-Mexican Volcanic Belt. The 'western arid region' is east of and (except for Mojave sky islands) discontiguous from the Mojave Desert, [9] unlike the southwestern Great Basin deserts adjacent with ecotones to the northern Mojave Desert.
