What US government agency manages the national parks?

The United States government agency tasked with the vital role of overseeing the nation's treasured natural and historical sites is the National Park Service. This dedicated bureau, part of the Department of the Interior, is responsible for managing the extensive National Park System, ensuring these special places are protected and accessible for all. Its core mission is to conserve the scenery, natural and historic objects, and wildlife within these areas, while also providing for their enjoyment in a way that leaves them unimpaired for future generations.

The National Park Service was officially established on August 25, 1916, when President Woodrow Wilson signed the Organic Act into law. Before its creation, individual national parks and monuments, such as Yellowstone (Review), which was designated the world's first national park in 1872, were managed by various entities, including the U.S. Army and the Department of the Interior, often without a unified approach. The Organic Act provided the much-needed centralized management and a clear mandate to balance the preservation of these irreplaceable resources with public access and education.

Today, the National Park Service's responsibilities extend far beyond just the iconic national parks. The agency manages over 430 units across more than 85 million acres, encompassing a diverse array of protected lands and sites. This includes national monuments, historic sites, battlefields, national seashores, recreation areas, and more, each with its own unique natural or cultural significance. Through its work, the National Park Service safeguards a vast tapestry of American heritage and natural beauty, offering countless opportunities for education, inspiration, and outdoor recreation across the country.
