The concept of a "national park" is an American innovation. It grew out of the conservation movement that began in the nineteenth century, when early travellers and writers, including naturalist John Muir, advocated for the protection of America’s natural landscapes from commercial interest and development.

In 1864, the Yosemite Grant was signed by President Abraham Lincoln to protect land in the magnificent Yosemite Valley. And with it, for the first time, the government set aside parkland for preservation and public use. It also paved the way for eventual creation of National Park Service.

Just 8 years later, when Yellowstone was designated a national park in 1872 in the historic Yellowstone National Park Protection Act, it became the first such park in the world.  On August 25, 1916, President Woodrow Wilson established the NPS to consolidate management of America’s federal parklands under one agency. The National Park System of the United States now comprises more than 400 areas covering more than 84 million acres in 50 states, the District of Columbia, American Samoa, Guam, Puerto Rico, Saipan, and the Virgin Islands.
