Wilderness is an area “…where the earth and its community of life are untrammeled by man, where man himself is a visitor who does not remain…”
The Wilderness Protection Act of 1964 established federally-managed lands preserved as large, roadless tracts where mechanized vehicles and equipment are not permitted, where permanent evidence of modern human occupation is not allowed, and where future development is not considered. In 1976 about eighty percent of Joshua Tree National Monument was designated wilderness. The 1994 California Desert Protection Act added 163,800 acres of wilderness, bringing the park total to 585,000 acres.
