Joshua Tree National Park
Franklin D. Roosevelt used the power of the 1906 Antiquities Act to establish Joshua Tree National Monument. In 1950, the size of the park was reduced by about 290,000 acres to open the land to more mining. The monument was redesignated as a national park on October 31, 1994, by the Desert Protection Act, which also added back 234,000 acres. Two distinct desert ecosystems, the Mojave and the Colorado, come together in Joshua Tree National Park. A fascinating variety of plants and animals make their homes in a land sculpted by strong winds and occasional torrents of rain.
