The National Park Service (NPS) is an agency of the U.S. federal government responsible for managing and protecting national parks, monuments, and other conservation areas. Established in 1916, the NPS operates under the Department of the Interior and plays a crucial role in preserving natural and cultural resources while ensuring public enjoyment of these lands. The agency's work reflects broader themes of federalism, as it involves cooperation between federal and state governments in conservation efforts and land management.
