Starting in 1876, and undergoing a series of name changes, the U.S. Forest Service grew to protect and utilize millions of acres of forest on public land. Gifford Pinchot, an early advocate of scientific forestry, along with President Theodore Roosevelt and conservation organizations, led the effort to manage forest for the public good.
In 1876, Congress created the office of Special Agent in the Department of Agriculture to assess the state of the forests in the United States. Franklin B. Hough was appointed the head of the office. In 1881, the office was expanded into the newly formed Division of Forestry. The Forest Reserve Act of 1891 authorized withdrawing land from the public domain as "forest reserves," managed by the Department of the Interior. In 1901, the Division of Forestry was renamed the Bureau of Forestry. The Transfer Act of 1905 transferred the management of forest reserves from the General Land Office of the Interior Department to the Bureau of Forestry, henceforth known as the US Forest Service. Gifford Pinchot was the first Chief Forester of the US Forest Service. In 1911, Congress passed the Weeks Act, authorizing the government to purchase private lands for stream-flow protection, and to maintain the lands as national forests. This made it possible for the national forest system to expand into the eastern United States.
Significant federal legislation affecting the Forest Service includes the Weeks Act of 1911, the Multiple Use - Sustained Yield Act of 1960, P.L. 86-517; the Wilderness Act, P.L. 88-577; the National Forest Management Act, P.L. 94-588; the National Environmental Policy Act, P.L. 91-190; the Cooperative Forestry Assistance Act, P.L. 95-313; and the Forest and Rangelands Renewable Resources Planning Act, P.L. 95-307.
