Mojave

National Preserve - California

Mojave National Preserve is in Southern California, in the Mojave Desert. It spans woodland, rugged mountains and canyons and shelters animals like mountain lions, coyotes and bats. The huge, steep sand mounds of the Kelso Dunes are known for making "singing" sounds. Cima Dome is a large granite mass covered with Joshua trees. The Hole-in-the-Wall cliffs are peppered with holes and crevices.

Cima Dome is a large granite mass covered with Joshua trees. The Hole-in-the-Wall cliffs are peppered with holes and crevices. Mojave preserves a diverse mosaic of ecological habitats and a 10,000 year history of human connection with the desert. Offering extensive opportunities to experience desert landscapes, the preserve promotes understanding and appreciation for the increasingly threatened resources of the Mojave Desert. This remote preserve encourages a sense of discovery and a connection to wild places. Note: There is no fuel inside the Preserve. Please fill up with gas BEFORE you enter. Park headquarters in Barstow, California is 60 miles from the Preserve, and offers maps, a bookstore and information. Our main visitor center, Kelso Depot, is located inside the Preserve, 95 miles east of Barstow, and 90 miles west of Las Vegas, at the intersection of Kelso-Cima and Kelbaker Roads. Hole-in-the-Wall Information Center Information, park brochures, drinking water, and passport stamps are available. Limited maps, books, postcards and other items available for purchase with the Western National Parks Association. Public Wifi available for paying campground fees on Pay.Gov.

From I-40: Exit Essex Road and drive north 10 miles to the junction with Black Canyon Road. Hole-in-the-Wall is 10 miles north on Black Canyon Road. Kelso Depot Visitor Center Originally opened in 1924 as a train station, Kelso Depot was renovated and reopened in 2005 a Visitor Center for Mojave National Preserve. Former dormitory rooms contain exhibits describing the cultural and natural history of the surrounding desert. The baggage room, ticket office and two dormitory rooms have been furnished to illustrate depot life during the first half of the twentieth century. A 20-minute orientation film is shown in the theater. Note: Kelso Depot is currently closed for repairs. From I-15: Exit Kelbaker Road at Baker, Calif., and drive south 34 miles to Kelso Depot. From I-40: Exit Kelbaker Road (28 miles east of Ludlow, Calif.) and drive north 22 miles to Kelso Depot.

For the remaining herds to survive, management may always be necessary. Protecting wild lands is key to the survival of these amazing animals. Desert bighorn sheep, NPS/Shawn Cigrand Respiratory Disease Outbreak Among Bighorn Sheep in Joshua Tree National Park Bighorn sheep were once common in Southern California and Nevada, but after more than a century of impacts from disease, unregulated hunting, and habitat loss, their numbers were in sharp decline. Since the 1960s, cooperative efforts from state and federal agencies to rebuild the herds were paying off, but now a disease outbreak at Joshua Tree National Park may pose a major threat to the majestic animals. bighorn sheep lamb showing symptoms of disease, with adult bighorn nearby General Patton's World War II Training Ground in the Mojave The Mojave Desert, a "wasteland" with easy railroad access, seemed to General George S.

Changing Patterns of Water Availability May Change Vegetation Composition in US National Parks Across the US, changes in water availability are altering which plants grow where. These changes are evident at a broad scale. But not all areas experience the same climate in the same way, even within the boundaries of a single national park. A new dataset gives park managers a valuable tool for understanding why vegetation has changed and how it might change in the future under different climate-change scenarios.

Park News & Guide National Park Service U.S. Department of the Interior Issue 25/2015-2016 COURTESY NASA/JET PROPULSION LABORATORY--CALTECH Mojave National Preserve Black Canyon campground with a sky added from an astrophoto A Head Start for Endangered Tortoises? By Phillip Gomez NPS/KNIGHTEN An unpretentious little building surrounded by a security fence just off Ivanpah Road near the northeast entrance to Mojave National Preserve has an ambitious purpose: to improve the chances of baby desert tortoises to survive to maturity and to produce vital offspring. The cryptic lives of tortoises—spent predominantly in underground burrows— and the many years that it takes for them to reach sexual maturity and to reproduce have made it difficult for conservation biologists to conduct field studies. For this long-term research project, juvenile tortoises are being “recruited” over a 20-year period and nurtured in this facility until they are capable of joining the Ivanpah Valley’s population with a reasonable chance for survival. The idea for this experiment in wildlife management, entitled Desert Tortoise Juvenile Survivorship at Mojave National Preserve—or Head Start to researchers—is similar to the principle underlying children’s nursery schooling: giving kids a head start in life. Welcome to Mojave National Preserve. We are glad you have made the decision to spend some of your time exploring and discovering the treasures of the Mojave Desert. NPS/GOMEZ So, the National Park Service, together with the U.S. Fish and Wildlife Service, Chevron Corp., Molycorp Inc., and two universities have partnered to create a working facility to try to gain a better understanding of tortoise behavior that affects their survival. The Ivanpah Desert Research Facility is staffed by a small team of faculty and Ph.D. candidates from the Savannah River Ecology Laboratory of the University of Georgia and from the University of California, Davis. Welcome to Mojave! Two yearling tortoise siblings explore their enclosure. The smaller one follows “big brother,” who became sick and was taken inside for the winter. In the case of the tortoise, the goal is to gain time for the reptile’s shell to develop and harden to make the young reptiles safe from predators. Adult tortoises with hardened shells have few predators, but juveniles are extremely vulnerable for the first four or five years of life. a small percentage make it to adulthood,” Hughson said. “It’s all about the predation,” says Debra Hughson, the Preserve’s chief of science and resource stewardship. “The purpose of Head Start is to allow them to survive.” How many tortoises are there in the Preserve? “Nobody knows exactly, but only Once numerous in the Mojave, the desert tortoise began experiencing loss of natural habitat from a variety of sources by the late 1980s: exurban sprawl, overgrazing by livestock, poaching, invasive plants, development of highways and dirt roads, and expanding use of off-road recreational vehicles. The degradation and fragmentation of habitat create barriers for the slowmoving tortoise in its search for food and water and also bring danger from motorists and off-roaders. Eggs of the unborn are sometimes trampled. Also, the lives of many are cut short by an upper-respiratory disease, possibly introduced into the desert by sick pet tortoises that were turned loose by their owners. This, coupled with the late maturity of the tortoise, which can take 18 to 20 years to reach breeding age, makes for long odds in the game of survival in the desert. Tortoise numbers have diminished by as much as 90 percent in some areas of the Mojave, according to Hughson. NPS COLLECTION In August 1989, the California Fish and Game Commission listed the desert tortoise (Gopherus agassizii) as a threatened species under the U.S. Endangered Species Act of 1973. The U.S. Fish and Wildlife Service followed suit with federal protection in 1991.
