Which organization is responsible for managing law enforcement services within national park boundaries?

The National Park Service (NPS) is responsible for managing law enforcement services within national park boundaries. This agency is tasked with the protection and management of national parks and the resources they contain, which includes ensuring public safety, enforcing laws related to park regulations, and preserving the natural and cultural resources found within these protected areas. Park rangers, who are part of the NPS, have law enforcement authority and handle various situations such as visitor safety, wildlife protection, and resource management, making NPS the central authority for law enforcement in these locations.

The other organizations listed serve different purposes and jurisdictions. The Federal Bureau of Investigation focuses on federal law enforcement and investigations covering a wide range of criminal activities nationwide but does not specifically manage law enforcement in national parks. The U.S. Forest Service oversees national forests and grasslands and is responsible for their management and law enforcement, but it does not extend its authority over national parks. The National Wildlife Federation is an advocacy organization focused on wildlife conservation and does not have law enforcement responsibilities.
