Department of the Interior responsibilities for national parks began with a single public reservation called Yellowstone National Park, which was established on March 1, 1872. With an increasing awareness of the need for wilderness preservation, more parks were gradually created. In order to effectively manage these national treasures, each of which were initially managed independently, the National Park Service was set up in the Department of the Interior, by an act of August 25, 1916.
