モハーヴェ砂漠
The Mojave Desert has a relatively stable and intact conservation status. In fact, the Mojave Desert is one of the best protected distinct ecoregions in the United States, as a result of the California Desert Protection Act, which established the Death Valley, Joshua Tree National Parks and the Mojave National Preserve. However, the Southwest and central East portions of the Mojave desert are particularly threatened as a result of off-road vehicles, human development, and agricultural grazing. The World Wildlife Fund lists the Mojave desert as relatively "stable/intact."
