The mission of the National Park Service is to "preserve unimpaired the natural and cultural resources and values of the national park system for the enjoyment, education, and inspiration of this and future generations." Accomplishing this mission requires ongoing investments in facilities, maintenance, and visitor services.
Recreation fees provide a vital source of revenue for improving facilities and services for park visitors. The National Park Service collects entrance fees under the Federal Lands Recreation Enhancement Act (FLREA), passed by Congress and signed into law by President George W. Bush in 2004.
Eighty percent of entrance fees collected at Joshua Tree National Park stay in the park and are used for projects directly related to visitor enjoyment, resource protection, and safety. The remaining 20 percent is distributed throughout the national park system, helping to support park units that do not collect fees.
