The Mojave Desert Network (MOJN) is one of 32 vital signs monitoring networks across the NPS. The majority of network parks are within the Great Basin-Mojave Desert region, which forms a broad wedge between the Sierra Nevada, the Transverse ranges, the Southern Rocky Mountains, and the Columbia and Colorado plateaus. MOJN is comprised of seven units: Death Valley National Park, Great Basin National Park, Joshua Tree National Park, Lake Mead National Recreation Area, Manzanar National Historic Site, Mojave National Preserve, and Parashant National Monument.

Biological diversity across the network is concentrated primarily in riparian habitats (e.g. springs, oases, stream corridors), montane islands, and specialized habitats (e.g. sand dunes). The network parks contain a variety of regionally, nationally, and globally significant resources. Network parks are often characterized by significant topographic relief and elevation gradients. These elevation gradients influence temperature regimes (though the interaction of air density, solar radiation, precipitation, and slope), soil development and ultimately the distribution of plant and animal communities across the region.
