Mojave National Preserve is a United States National Preserve located in the Mojave Desert of San Bernardino County, California, US, between Interstate 15 and Interstate 40. The preserve was established October 31, 1994, with the enactment of the California Desert Protection Act by the United States Congress, which also established Joshua Tree National Park and Death Valley National Park as National Parks. Previously, some lands contained within the Preserve were the East Mojave National Scenic Area, under the jurisdiction of the Bureau of Land Management. At 1,542,776 acres (6,243 km2), within the contiguous United States it is the third largest unit of the National Park System and the first largest National Preserve. The preserve was created within the Pacific West Region of the National Park Service and remains within that jurisdiction today.
Owens Valley is an arid valley of the Owens River in eastern California in the United States. It is located to the east of the Sierra Nevada, west of the White Mountains and Inyo Mountains, and is split between the Great Basin Desert and the Mojave Desert. The mountain peaks on the West side reach above 14,000 feet (4,300 m) in elevation, while the floor of the Owens Valley is about 4,000 feet (1,200 m), making the valley the deepest in the United States. The Sierra Nevada casts the valley in a rain shadow, which makes Owens Valley "the Land of Little Rain". The bed of Owens Lake, now a predominantly dry endorheic alkali flat, sits on the southern end of the valley.
The Transverse Ranges are a group of mountain ranges of southern California, in the Pacific Coast Ranges physiographic region in North America. The Transverse Ranges begin at the southern end of the California Coast Ranges and lie within Santa Barbara, Ventura, Los Angeles, San Bernardino, Riverside and Kern counties. The Peninsular Ranges lie to the south. The name is due to the ranges' east–west orientation, making them transverse to the general northwest–southeast orientation of most of California's coastal mountains.
The ecology of California can be understood by dividing the state into a number of ecoregions, which contain distinct ecological communities of plants and animals in a contiguous region. The ecoregions of California can be grouped into four major groups: desert ecoregions, Mediterranean ecoregions, forested mountains, and coastal forests.
