The California Desert Protection Act of 2010 (S.2921) is legislation proposed by U.S. Senator Dianne Feinstein. The stated aim of the legislation is to provide for conservation, enhanced recreation opportunities, and development of renewable energy in the California Desert Conservation Area..
The bill consists of two titles, the first affecting conservation and recreation and the second affecting renewable energy permitting.
The conservation title creates two new national monuments: the 941,000 acres (3,810 km2; 1,470 sq mi) Mojave Trails National Monument along Route 66 and the 134,000 acres (540 km2; 209 sq mi) Sand to Snow National Monument, which connects Joshua Tree National Park to the San Bernardino Mountains, allowing seasonal wildlife migrations and providing access to year-round springs in the Big Morongo Canyon Preserve. It expands Death Valley National Park, Joshua Tree National Park, and the Mojave National Preserve, designates 344,000 acres (1,390 km2; 538 sq mi) of additional wilderness on federal lands, and adds 76 miles (122 km) of wild and scenic river designation. Finally, it designates specific areas for off-road vehicle use throughout the California desert.
