Which law governs the activities of park rangers in the U.S.?

The National Park Service Organic Act of 1916 is the foundational law that governs the activities of park rangers in the United States. This act established the National Park Service (NPS) and outlined its mission to conserve park resources and provide for public enjoyment while ensuring that such enjoyment does not impair the parks’ natural and cultural resources. It solidifies the responsibilities of park rangers, emphasizing their role in protecting these special places as well as facilitating safe and educational visitor experiences.

The other options, while significant in their own rights, address specific environmental protections or areas but do not encompass the broad responsibilities and duties of park rangers like the Organic Act does. For example, the National Wilderness Preservation Act focuses on creating a system of protected wilderness areas, while the Endangered Species Act aims to protect threatened and endangered species. The Clean Water Act primarily deals with water pollution control but does not specifically govern the operations of park rangers. Thus, the Organic Act remains the core legislative mandate under which park rangers operate and fulfill their duties.
