Which federal agency oversees the National Park Service?

The National Park Service (NPS) is overseen by the U.S. Department of the Interior. This department is responsible for managing federal land and natural resources, which includes national parks, wildlife refuges, and other public lands. The NPS falls under this department's mandate as its primary agency for national park management and conservation, ensuring the protection and preservation of these environments for future generations.

The U.S. Department of the Interior encompasses a variety of agencies, each with its own specific roles in land management, environmental protection, and resource conservation. This structure allows for a focused approach to maintaining the cultural and natural heritage found in national parks while also facilitating recreational opportunities for the public.

The other agencies mentioned do not hold the same jurisdiction over national parks. The Department of Homeland Security focuses primarily on domestic security and response, the U.S. Department of Agriculture deals mainly with farming, food, and rural development, and the Department of Energy is concentrated on energy production and resources. Therefore, understanding the role of the U.S. Department of the Interior in overseeing the NPS is crucial for grasping the management of national parks.
