Biogeographic Regions of Arizona
Mojave Desert Region
The Mojave Desert region covers a portion of northwestern Arizona
west of the Grandwash Cliffs of the Grand Canyon and stretching
southward to the Hualapai Mountains near Kingman. Despite very
low annual rainfall and blistering summer temperatures, several
well-adapted plants and animals manage to grow in this environment
including the distinctive joshua tree.
Biotic communities found in the Mojave Desert Region of Arizona include Mojave Desertscrub, Great Basin Desertscrub, Grassland, Pinon Pine-Juniper Woodland, Montane Ponderosa Pine Forest and Northern Arizona Riparian Woodland.
