The National Park Service (NPS) is a U.S. federal agency responsible for managing and preserving the nation's national parks, monuments, and other historical sites. Established in 1916, the NPS aims to protect the natural and cultural resources of these areas while providing opportunities for public enjoyment and education. With over 400 sites across the country, including iconic locations like Yellowstone and Yosemite, the NPS plays a crucial role in conservation efforts. The agency works to balance ecological preservation with recreational access, ensuring that future generations can experience the beauty and history of America's landscapes.
