Joshua Tree National Park

In 1936, President Franklin D. Roosevelt set aside 825,000 acres of California desert as Joshua Tree National Monument. The park was later reduced to 560,000 acres. However, Congress passed the California Desert Protection Act of 1994 that expanded the park to 794,000 acres and raised its level of protection to National Park status.
