Mojave National Preserve California
A fact sheet from 2017 Dougall Photography/iStockphoto Mojave’s $131.8 million maintenance backlog includes repairs to historic buildings such as the Kelso Depot. Shane McMurphy/iStockphoto Mojave National Preserve California Overview Two hours from the hustle and bustle of Las Vegas and 100 miles from the nearest lodging lies California’s Mojave National Preserve. The Las Vegas Review-Journal dubbed this vast desert in San Bernardino County the “perfect escape for those seeking serenity.” The preserve spans 1.6 million acres, making it the third-largest National Park Service (NPS) unit in the contiguous United States. Mojave is ecologically and geologically diverse, with towering sand dunes, dun-colored mesas, and volcanic formations providing habitat for its abundant plants and wildlife. In addition to the densest forest of Joshua trees in the world, visitors can see bighorn sheep, bobcats, golden eagles, and breathtaking displays of seasonal wildflowers. The preserve also has a rich cultural heritage. Lands first inhabited by the Chemehuevi and Mojave tribes attracted gold miners in the late 19th century and were later crossed by several railroad lines. Visitors can learn more about this history through exhibits at the visitor center and by exploring archaeological sites, abandoned mines, and preserved homesteads and other buildings. The ghost town of Kelso, which once served as a Union Pacific Railroad depot and mining outpost, is one of the park’s most popular destinations. Unfortunately, Mojave faces over $131 million in deferred maintenance. Maintenance challenges Nearly all of Mojave’s needed repairs are for its road network. Severe deterioration of some sections of pavement has prompted the NPS to warn visitors of dangerous potholes.

There are currently 19 National Historic Trails in the United States. In 1968, the National Trails System Act, which is intended to provide for the outdoor recreation needs of the public, opened the door to federal involvement in all types of trails. Today, the Bureau of Land Management, along with the National Park Service and National Forest Service, are responsible for the administration and management of National Historic Trails.

Mojave National Preserve Management Plan for Developed
Mojave National Preserve—Management Plan for Developed Water Resources CHAPTER 3: AFFECTED ENVIRONMENT Introduction This chapter describes the unique factors that influence water resource management in the Preserve and the resources that could be affected by the implementation of any of the alternatives described in Chapter 2: Alternatives. The resource descriptions provided in this chapter serve as a baseline to compare the potential effects of the management actions proposed in the alternatives. The following resource topics are described in this chapter: • Environmental Setting • Cultural Resources • Water Resources • Wilderness Character • Wildlife Environmental setting and water resources are important for context and are foundational for water resource management, but are not resources that are analyzed for effects. Resource issues that were considered and dismissed from further analysis are listed in Chapter 1: Purpose of and Need for Action and are not discussed further in this EA. A description of the effects of the proposed alternatives on wildlife, cultural resources, and wilderness character is presented in Chapter 4: Environmental Consequences. Environmental Setting The Preserve includes an ecologically diverse yet fragile desert ecosystem consisting of vegetative attributes that are unique to the Mojave Desert, as well as components of the Great Basin and Sonoran Deserts. Topography The topography of the Preserve is characteristic of the mountain and basin physiographic pattern, with tall mountain ranges separated by corresponding valleys filled with alluvial sediments. Primary mountain ranges in the Preserve, from west to east, include the Granite, Kelso, Providence, Clark, New York, and Piute Mountains. Major alluvial valleys include Soda Lake (dry lake bed), Shadow Valley, Ivanpah Valley, Lanfair Valley, and Fenner Valley.

The only people who live there now are a handful of reserve personnel — mostly resident managers and stewards — who care for these wildlands, their resources and facilities, and who enable the teaching and research to continue across California.

Military Overflight Management and Education Program— Immersion and Communication
Military Overflight Management and Education Program— Immersion and Communication Gregg D. Fauth, Wilderness Coordinator, Sequoia and Kings Canyon National Parks, 47050 Generals Highway, Three Rivers, CA 93271; [email protected] Park background Sequoia and Kings Canyon National Parks (SKCNPs) are in the southern Sierra Nevada of California and contain some 865,000 acres of land ranging from foothill to alpine environ- ments. Twelve of the fifteen 14,000-foot-high (4267m) peaks in California are contained within these High Sierra parks, including the highest peak in the lower 49 states, Mt. Whitney at 14,495 ft. (4418m) elevation. The parks are very popular for backpacking and recreational stock use, hosting some 30,000 annual wilderness visitors spending some 100,000 nights camping in the parks’ wilderness. Sequoia and General Grant national parks (NPs) were established in 1890. These parks were: “set apart as a public park, or pleasure ground, for the benefit and enjoyment of the people” and to “provide for the preservation from injury of all timber, mineral deposits, nat- ural curiosities or wonders within said park, and their retention in their natural state.” Gen- eral Grant NP later evolved and expanded to become Kings Canyon NP in 1940 when its purpose was stated as: “That in order to insure the permanent preservation of the wilderness character of the Kings Canyon National Park, the Secretary of the Interior may limit the char- acter and number of privileges that he may grant within the Kings Canyon National Park.” The passage of the Wilderness Act in 1964 included a directive to the Secretary of In- terior to survey park land for wilderness designation.
