Map of Wilderness Areas in the Western USThe National Wilderness Preservation System

After over 8 years of drafts, Howard Zahniser of the Wilderness Society wrote the version Congress finally passed as the Wilderness Act (text). Signed into law on September 3, 1964, the act created the National Wilderness Preservation System. Wallace Stegner’s beautiful and timeless “Wilderness Letter” introduced the act defining wilderness.

“A wilderness, in contrast with those areas where man and his own works dominate the landscape, is hereby recognized as an area where the earth and its community of life are untrammeled by man, where man himself is a visitor who does not remain.”

Initially the act designated 9 million acres of Forest Service lands. The Forest Service, National Park Service and Fish and Wildlife service were required to review all their lands for inclusion. In 1968 the first Fish and Wildlife lands, the Great Swamp of New Jersey were designated. Later, in 1970, Craters of the Moon became the first designated National Monument land. The Petrified Forest became the first designated National Park.

Qualities of Wilderness Lands

Qualifying lands must: be owned and managed by the federal government with at least five thousand acres. Lands must have a “substantially unnoticeable” human influence, contain opportunities for solitude and recreation, and possess “ecological, geological, or other features of scientific, educational, scenic, or historical value.”

No wheels are allowed, trail workers uses only hand tools and dynamite. Supplies are typically transported by horse. While the President can authorize dams in wilderness areas, congress has to approve funds. The Wild and Scenic Rivers Act was passed in 1968 to in part to close this option.

Today, Forest Service, Fish and Wildlife (National Wildlife Refuges), BLM, and National Park Lands including National Monuments, are eligible for Wilderness designation. However, Wilderness Areas only began to include BLM land in 1976 with the passage of the Federal Land Policy and Management Act. The act stated that for the long term BLM lands could remain owned by the government. The government then assessed these lands in the late 1970’s and early 1980’s for wilderness designation. As a result so much BLM land became designated wilderness during that era.

There are also State and Tribal Wilderness Areas.

National Parks manage additional lands as wilderness that are not designated due to their policy of having “other categories of wilderness.” Between designated wilderness and the “other categories” over 80% of National Park land is managed as wilderness.

The Lands

The act originally protected 9 million acres of Wilderness. Currently by far the most Wilderness Areas are in Alaska hence the thirteen largest are in the state. With 3.1 million acres, Death Valley possess the most wilderness in the lower 48 states (14th overall). The Magruder Corridor Road separates the next two largest in the lower 48, the Frank Church River of No Return Wilderness (2.3 million acres) and Selway Bitterroot (1.3 million acres). Many classic western rivers float through Wilderness Areas. Today 765 Wilderness Areas protect over 110 million acres with over 50% of the land being in Alaska, California is next with 14% and then Idaho, Arizona and Washington all have about 4%.

Who Manages Wilderness Areas

Wilderness Areas in National Parks as well as many National Monuments are managed by the National Park Service (established August 25, 1916) within the Department of the Interior. Prior to this National Parks were managed differently from state to state. Interestingly National Monuments were managed by the Department of Agriculture until 1933 when Franklin Roosevelt signed two Executive Orders moving National Monuments, War Department Historic sites, and some D.C. parks under the management of the NPS.

National Monuments are managed by NPS, FS, F&Wildlife, BLM, National Oceanic and Atmospheric Administration (manages marine national monuments). Approximately 56% of wilderness acreage is managed by the National Park Service. The Forest Service manages 18%, US Fish and Wildlife 22% and BLM 4%.

History of National Monuments

National Monuments can contain non-federal land. National Monuments arose out of the Antiquities Act of 1906 which enabled the President to protect lands. That year President T. Roosevelt used the act to create Devil’s Postpile National Monument. In 1908, he made Grand Canyon National Monument which was fought in court. However, the Monument was upheld in 1920 by the US Supreme Court. Further cases have maintained the President’s power to designate areas. Grand Canyon was designated a national park on February 26, 1919.

In 1996, President Clinton established Grand Staircase-Escalante as the first national monument to be administered by the BLM which is also in the Department of the Interior. BLM Monuments and Wilderness areas are under the umbrella of the National Landscape Conservation System. Also known as the National Conservation Lands, it was created in 2000 and stayed in a precarious state until solidified with the passing of the National Landscape Conservation System Act in March 2009. The BLM is tasked with the responsibility to “conserve, protect, and restore these nationally significant landscapes that have outstanding cultural, ecological, and scientific values for the benefit of current and future generations.” Conservation Areas include National Monuments, National Conservation Areas, Wilderness Areas, Wilderness Study Areas, Wild and Scenic Rivers, National Scenic Trails, National Historic Trails, and Other Areas.
