Ecoregion in CA

Generate High-Quality PDF

The Arid Montane Slopes ecoregion is diverse, has Mojave Desert influences, and has vegetation communities ranging from desert scrub to semi-desert montane chaparral to singleleaf pinyon-California juniper woodlands. It stretches along the northern side of the San Gabriel and San Bernardino Mountains, with elevations about 3,000 to 7,000 feet. The geology is mostly granitic and gneissic rocks. There also are areas of carbonate geology (limestone and dolomite) in the San Bernardino Mountains that provide unique habitat for several endangered endemic plants.
