The National Wilderness Preservation System (NWPS) of the United States protects federally managed wilderness areas designated for preservation in their natural condition. Activity on formally designated wilderness areas is coordinated by the National Wilderness Preservation System. Wilderness areas are managed by four federal land management agencies: the National Park Service, the U.S. Forest Service, the U.S. Fish and Wildlife Service, and the Bureau of Land Management.
The term wilderness is defined as "an area where the earth and community of life are untrammeled by man, where man himself is a visitor who does not remain" and "an area of undeveloped Federal land retaining its primeval character and influence, without permanent improvements or human habitation, which is protected and managed so as to preserve its natural conditions".
As of 2021 [update] , 803 wilderness areas have been designated, totaling 111,368,221 acres (45,069,120 ha; 450,691.20 km2; 174,012.845 sq mi), which comprise about 4.5% of the land area of the United States.
During the 1950s and 1960s, as the American transportation system was on the rise, concern for clean air and water quality began to grow. A conservation movement began to take place with the intent of establishing designated wilderness areas. Howard Zahniser created the first draft of the Wilderness Act in 1956. It took nine years and 65 rewrites before the Wilderness Act was finally passed in 1964. 3, 1964. The Wilderness Act mandated that the National Park Service, U.S. Forest Service, and U.S. Fish and Wildlife Service review all federal lands under their jurisdiction for wilderness areas to include in the NWPS. The first national forest wilderness areas were established by the Wilderness Act itself. The Great Swamp in New Jersey became the first National Wildlife Refuge with formally designated wilderness in 1968. Wilderness areas in national parks followed, beginning with the designation of wilderness in part of Craters of the Moon National Monument in Idaho in 1970.The Wilderness Act of 1964 (Public Law 88-577), which established the NWPS, was signed into law by President Lyndon B. Johnson on September
A dramatic spike in acreage added to the wilderness system in 1980 was due in large part to the Alaska National Interest Lands Conservation Act, signed into law by President Jimmy Carter on December 2, 1980. 21, 1976, when the Federal Land Policy and Management Act of 1976 was signed into law; designation of wilderness areas on BLM lands began in 1978. Over 200 wilderness areas have been created within Bureau of Land Management administered lands since then, consisting of approximately 8.71 million acres (3,520,000 ha) in September 2015.A smaller spike in 1984 came with the passage of many bills establishing national forest wilderness areas identified by the Forest Service's Roadless Area Review and Evaluation (RARE) process. The Bureau of Land Management was not required to review its lands for inclusion in the NWPS until after October
As of August 2008, 704 separate wilderness areas, encompassing 107,514,938 acres (43,509,752 ha), had become part of the National Wilderness Preservation System. On March 30, 2009, President Barack Obama signed into law the Omnibus Public Land Management Act of 2009. The legislation designated an additional 2 million acres (810,000 ha) in nine states as wilderness, representing the largest expansion of wilderness lands since 1984. The John D. Dingell, Jr. Conservation, Management, and Recreation Act of 2019 added another 1.3 million acres (530,000 ha) in 43 new and expanded wilderness areas.
On federal lands in the United States, Congress may designate an area as wilderness under the provisions of the Wilderness Act of 1964.Multiple agencies, including the Bureau of Land Management, the National Park Service, the Fish and Wildlife Service, and the U.S. Forest Service, are responsible for the submission of new areas that fit the criteria to become wilderness to Congress. Congress then reviews these cases on a state by state basis and determines which areas and how much land in each area will become part of the WPS. There have been multiple occasions in which Congress designated more federal land than had been recommended by the nominating agency. Whereas the Wilderness Act stipulated that a wilderness area must be "administered for the use and enjoyment of the American people in such a manner as will leave them unimpaired for future use and enjoyment as wilderness", the Eastern Wilderness Areas Act of 1975, which added 16 national forest areas to the NWPS, allowed for the inclusion of areas that had been severely modified by human interference.
The Wilderness Act provides criteria for lands being considered for wilderness designation. Though there are some exceptions, the following conditions must be present for an area to be included in the NWPS: (1) the land is under federal ownership and management, (2) the area consists of at least five thousand acres of land, (3) human influence is "substantially unnoticeable," (4) there are opportunities for solitude and recreation, and (5) the area possesses "ecological, geological, or other features of scientific, educational, scenic, or historical value."
Wilderness areas are subject to specific management restrictions; human activities are limited to non-motorized recreation (such as backpacking, camping, hunting, fishing, horseback riding, etc.), scientific research, and other non-invasive activities. During these activities, patrons are asked to abide by the Leave No Trace policy. This policy sets guidelines for using the wilderness responsibly, and leaving the area as it was before usage. These guidelines include: Packing all trash out of the wilderness, using a stove as opposed to a fire, camping at least 200 feet (61 m) from trails or water sources, staying on marked trails, and keeping group size small. When closely observed, the Leave No Trace ethos ensures that wilderness areas remain untainted by human interaction. In general, the law prohibits logging, mining, motorized or mechanized vehicles (including bicycles), road-building, and other forms of development in wilderness areas, though pre-existing mining claims and grazing ranges are permitted through grandfather clauses in the Wilderness Act. Wilderness areas fall into IUCN protected area management category Ia (strict nature preserves) or Ib (wilderness areas).
A special exemption to the rule against mechanized equipment is made for wilderness areas in Alaska: limited use of motorized vehicles and construction of cabins and aquaculture are permitted.These exemptions were allowed due to the large amount of wilderness in Alaska and the concerns of subsistence users, including Alaska Natives.
Wilderness areas are parts of national parks, wildlife refuges, national forests, and BLM lands; some units are managed by different agencies. Initially, the NWPS included 34 areas protecting 9.1 million acres (37,000 km2) in the national forests. As of 2019, there are 803 areas in the NWPS, preserving 111,368,221 acres (45,069,120 ha). This is approximately 4.5% of the entire United States, though only about 2.7% of the 48 contiguous states. However, most of that acreage is located in a handful of states. The states with the highest number of wildernesses are California, Arizona, Nevada, Alaska, and Oregon. However, when measured in acres the list changes dramatically, as Alaska contains many of the largest areas protected under the act. In terms of total acres, Alaska, California, Arizona, Idaho, and Washington are the top five states for wilderness, containing almost 80 percent of the acreage in the system. Wilderness totals in most eastern states are modest, with the exceptions of Florida and Minnesota. Wilderness areas exist in every state except Connecticut, Delaware, Iowa, Kansas, Maryland, and Rhode Island.
Most U.S. wilderness areas are in national forests, but the largest amount of wilderness land is administered by the National Park Service. The largest contiguous wilderness complex in the United States is the Noatak and Gates of the Arctic Wildernesses in Alaska at 12,743,329 acres (5,157,042 ha). The largest wilderness area outside Alaska is the Death Valley Wilderness in southeastern California. The smallest area protected by the WPS is the Pelican Island Wilderness in northern Florida, which measures just 6 acres (2.4 ha) total. The smallest area preserved in the system was formerly the Rocks and Islands Wilderness in Northern California at 5 acres (2.0 ha), but after a reassessment by the Bureau of Land Management in 2006 it was officially expanded to 19 acres (7.7 ha).
On November 7, 2009, an agreement between the United States, Canada, and Mexico entitled the "Memorandum of Understanding on Cooperation for Wilderness Conservation" was made. This agreement created a new entity, the North American Intergovernmental Committee on Cooperation for Wilderness and Protected Areas Conservation, that would streamline the process for open communication between international agencies for the purpose of wilderness preservation. This committee was formed to gain insight on the benefits of wilderness preservation, establish open channels of communication between international agencies, and examine the cultural differences and similarities behind preservation efforts in each country. Within the U.S. system, all of the agencies responsible for wilderness preservation will work in cooperation with their international counterparts to determine the future of both the U.S. system and North American preservation efforts as a whole.
One of the major goals of the Wilderness Preservation System is to provide undeveloped habitats for threatened or endangered species.Many of the species found in the United States are represented in wilderness areas. There are 261 basic ecosystems in the U.S., and 157 of them are represented in the system. With 60% of all ecosystems somewhat protected by the NWPS, much of the wildlife in the U.S. also has an area in which to exist without significant human interaction.
In late 2011, a full wilderness review was requested of the Arctic Refuge Coastal Plain in Alaska. One of the major qualifications for this area to be considered as a possible wilderness area was its diverse wildlife population, many of which are on the endangered species list.In this potential wilderness area alone, whales, seals, wolves, polar bears, grizzly bears, muskoxen, caribou, and over 200 species of migratory birds call this one area home for at least part of the year. This vast assortment of flora and fauna is a major consideration for addition into the wilderness preservation system.
Thousands of laws and policies have helped shape and manage the National Wilderness Preservation System in the United States. The following Acts of Congress either directly affect the wilderness system or help influence wilderness management.
|Agency||Wilderness area||Agency land|
|National Park Service||43,932,843 acres (17,778,991 ha)||56%|
|U.S. Forest Service||36,165,620 acres (14,635,710 ha)||18%|
|U.S. Fish and Wildlife Service||20,702,488 acres (8,378,000 ha)||22%|
|Bureau of Land Management||8,710,087 acres (3,524,847 ha)||2%|
|Total||109,511,038 acres (44,317,545 ha)|
Some state and tribal governments also designate wilderness areas under their own authority and local laws. These are not federal areas, and the exact nature of protection may differ from federal laws. Some U.S. states have created wilderness preservation programs modeled on the NWPS.
The United States Forest Service (USFS) is an agency of the U.S. Department of Agriculture that administers the nation's 154 national forests and 20 national grasslands. The Forest Service manages 193 million acres (780,000 km2) of land. Major divisions of the agency include the Chief's Office, National Forest System, State and Private Forestry, Business Operations, and Research and Development. The agency manages about 25% of federal lands and is the only major national land management agency not part of the U.S. Department of the Interior, which manages the National Park Service, the U.S. Fish and Wildlife Service, and the Bureau of Land Management.
In the United States, national forest is a classification of protected and managed federal lands. National forests are largely forest and woodland areas owned collectively by the American people through the federal government, and managed by the United States Forest Service, a division of the United States Department of Agriculture. The National Forest Service is also a forestry research organization who provides financial assistance to state and local forestry industry. As of 2020, there are 154 national forests in the United States.
The Tongass National Forest in Southeast Alaska is the largest U.S. National Forest at 16.7 million acres. Most of its area is temperate rain forest and is remote enough to be home to many species of endangered and rare flora and fauna. The Tongass, which is managed by the United States Forest Service, encompasses islands of the Alexander Archipelago, fjords and glaciers, and peaks of the Coast Mountains. An international border with Canada runs along the crest of the Boundary Ranges of the Coast Mountains. The forest is administered from Forest Service offices in Ketchikan. There are local ranger district offices located in Craig, Hoonah, Juneau, Ketchikan, Petersburg, Sitka, Thorne Bay, Wrangell, and Yakutat.
In the United States, a national monument is a protected area that can be created from any land owned or controlled by the federal government by proclamation of the President of the United States or an act of Congress. National monuments protect a wide variety of natural and historic resources, including sites of geologic, marine, archaeological, and cultural importance.
National Wildlife RefugeSystem is a designation for certain protected areas of the United States managed by the United States Fish and Wildlife Service. The National Wildlife Refuge System is the system of public lands and waters set aside to conserve America's fish, wildlife, and plants. Since President Theodore Roosevelt designated Florida's Pelican Island National Wildlife Refuge as the first wildlife refuge in 1903, the system has grown to over 568 national wildlife refuges and 38 wetland management districts encompassing more than 150,000,000 acres (607,028 km2).
In all modern states, a portion of land is held by central or local governments. This is called public land, state land, or Crown land. The system of tenure of public land, and the terminology used, varies between countries. The following examples illustrate some of the range.
Wilderness or wildlands, are natural environments on Earth that have not been significantly modified by human activity or any nonurbanized land not under extensive agricultural cultivation. The term has traditionally referred to terrestrial environments, though growing attention is being placed on marine wilderness. Recent maps of wilderness suggest it covers roughly one quarter of Earth's terrestrial surface, but is being rapidly degraded by human activity. Even less wilderness remains in the ocean, with only 13.2% free from intense human activity.
The protected areas of the United States are managed by an array of different federal, state, tribal and local level authorities and receive widely varying levels of protection. Some areas are managed as wilderness, while others are operated with acceptable commercial exploitation. As of 2020, the 36,283 protected areas covered 1,118,917 km2 (432,016 sq mi), or 12 percent of the land area of the United States. This is also one-tenth of the protected land area of the world. The U.S. also had a total of 787 National Marine Protected Areas, covering an additional 3,210,908 km2 (1,239,739 sq mi), or 37 percent of the total marine area of the United States.
The Alaska National Interest Lands Conservation Act (ANILCA) is a United States federal law signed by President Jimmy Carter on December 2, 1980. ANILCA provided varying degrees of special protection to over 157,000,000 acres (64,000,000 ha) of land, including national parks, national wildlife refuges, national monuments, wild and scenic rivers, recreational areas, national forests, and conservation areas. It was, and remains to date, the single largest expansion of protected lands in history and more than doubled the size of the National Park System.
The protected areas of Michigan come in an array of different types and levels of protection. Michigan has five units of the National Park Service system. There are 14 federal wilderness areas; the majority of these are also tribal-designated wildernesses. It has one of the largest state forest systems as well having four national forests. The state maintains a large state park system and there are also regional parks, and county, township and city parks. Still other parks on land and in the Great Lakes are maintained by other governmental bodies. Private protected areas also exist in the state, mainly lands owned by land conservancies.
The Wilderness Act of 1964 was written by Howard Zahniser of The Wilderness Society. It created the legal definition of wilderness in the United States, and protected 9.1 million acres (37,000 km²) of federal land. The result of a long effort to protect federal wilderness and to create a formal mechanism for designating wilderness, the Wilderness Act was signed into law by President Lyndon B. Johnson on September 3, 1964 after over sixty drafts and eight years of work.
National Conservation Lands, formally known as the National Landscape Conservation System, is a 35-million-acre (140,000 km2) collection of lands in 873 federally recognized areas considered to be the crown jewels of the American West. These lands represent 10% of the 258 million acres (1,040,000 km2) managed by the Bureau of Land Management (BLM). The BLM is the largest federal public land manager and is responsible for over 40% of all the federal public land in the nation. The other major federal public land managers include the US Forest Service (USFS), National Park Service (NPS), and the US Fish and Wildlife Service (USFWS).
The Santa Rosa and San Jacinto Mountains National Monument is a National Monument in southern California. It includes portions of the Santa Rosa and San Jacinto mountain ranges, the northernmost ones of the Peninsular Ranges system. The national monument covers portions of Riverside County, west of the Coachella Valley, approximately 100 miles (160 km) southeast of downtown Los Angeles.
The National Wildlife Refuge System in the United States has a long and distinguished history.
The Wilderness Society is an American non-profit land conservation organization that is dedicated to protecting natural areas and federal public lands in the United States. They advocate for the designation of federal wilderness areas and other protective designations, such as for national monuments. They support balanced uses of public lands, and advocate for federal politicians to enact various land conservation and balanced land use proposals. The Wilderness Society also engages in a number of ancillary activities, including education and outreach, and hosts one of the most valuable collections of Ansel Adams photographs at their headquarters in Washington, D.C.
According to the California Protected Areas Database (CPAD), in the state of California, United States, there are over 14,000 inventoried protected areas administered by public agencies and non-profits. In addition, there are private conservation areas and other easements. They include almost one-third of California's scenic coastline, including coastal wetlands, estuaries, beaches, and dune systems. The California State Parks system alone has 270 units and covers 1.3 million acres (5,300 km2), with over 280 miles (450 km) of coastline, 625 miles (1,006 km) of lake and river frontage, nearly 18,000 campsites, and 3,000 miles (5,000 km) of hiking, biking, and equestrian trails.
The Omnibus Public Land Management Act of 2009 is a land management law passed in the 111th United States Congress and signed into law by President Barack Obama on March 30, 2009. The bill designates millions of acres in the US as protected and establishes a National Landscape Conservation System. It includes funding for programs, studies and other activities by the Department of the Interior and the Department of Agriculture, and in some cases bars further geothermal leasing, oil and gas leasing, and new mining patents on certain stretches of protected land.
Conservation in the United States can be traced back to the 19th century with the formation of the first National Park. Conservation generally refers to the act of consciously and efficiently using land and/or its natural resources. This can be in the form of setting aside tracts of land for protection from hunting or urban development, or it can take the form of using less resources such as metal, water, or coal. Usually, this process of conservation occurs through or after legislation on local or national levels is passed.
The John D. Dingell Jr. Conservation, Management, and Recreation Act of 2019 is an omnibus lands act that protected public lands and modified management provisions. The bill designated more than 1,300,000 acres (5,300 km2) of wilderness area, expanded several national parks and other areas of the National Park System, and established four new national monuments while redesignating others. Other provisions included making the Land and Water Conservation Fund permanent, protecting a number of rivers and historic sites, and withdrawing land near Yellowstone National Park and North Cascades National Park from mining.
