International The
World Conservation Union (IUCN) classifies wilderness at two levels, 1a (
strict nature reserves) and 1b (Wilderness areas). There have been recent calls for the World Heritage Convention to better protect wilderness and to include the word wilderness in their selection criteria for Natural Heritage Sites Forty-eight countries have wilderness areas established via legislative designation as IUCN protected area management Category 1b sites that do not overlap with any other IUCN designation. They are: Australia, Austria, Bahamas, Bangladesh, Bermuda, Bosnia and Herzegovina, Botswana, Canada, Cayman Islands, Costa Rica, Croatia, Cuba, Czech Republic, Democratic Republic of Congo, Denmark, Dominican Republic, Equatorial Guinea, Estonia, Finland, French Guiana, Greenland, Iceland, India, Indonesia, Japan, Latvia, Liechtenstein, Luxembourg, Malta, Marshall Islands, Mexico, Mongolia, Nepal, New Zealand, Norway, Northern Mariana Islands, Portugal, Seychelles, Serbia, Singapore, Slovakia, Slovenia, Spain, Sri Lanka, Sweden, Tanzania, United States of America, and Zimbabwe. At publication, there are 2,992 marine and terrestrial wilderness areas registered with the IUCN as solely Category 1b sites. Twenty-two other countries have wilderness areas. These wilderness areas are established via administrative designation or wilderness zones within protected areas. Whereas the above listing contains countries with wilderness exclusively designated as Category 1b sites, some of the below-listed countries contain protected areas with multiple management categories including Category 1b. They are: Argentina, Bhutan, Brazil, Chile, Honduras, Germany, Italy, Kenya, Malaysia, Namibia, Nepal, Pakistan, Panama, Peru, Philippines, the Russian Federation, South Africa, Switzerland, Uganda, Ukraine, the United Kingdom of Great Britain and Northern Ireland, Venezuela, and Zambia. The government counts the whole area of the 16 national parks as wilderness. This means, also the managed parts are included in the "existing" 0,6%. There is no doubt, that Germany will miss its own time-dependent quantitative goals, but there are also some critics, that point a bad designation practice: Findings of disturbance ecology, according to which process-based nature conservation and the 2% target could be further qualified by more targeted area designation, pre-treatment and introduction of
megaherbivores, are widely neglected. Since 2019 the government supports bargains of land that will then be designated as wilderness by 10 Mio. Euro annually. The German minimum size for wilderness candidate sites is normally 10 km2. In some cases (i.e. swamps) the minimum size is 5 km2.
Finland There are twelve wilderness areas in the
Sami native region in northern
Finnish Lapland. They are intended both to preserve the wilderness character of the areas and further the traditional livelihood of the Sami people. This means e.g. that reindeer husbandry, hunting and taking wood for use in the household is permitted. As population is very sparse, this is generally no big threat to the nature. Large scale reindeer husbandry has influence on the ecosystem, but no change is introduced by the act on wilderness areas. The World Commission on Protected Areas (WCPA) classifies the areas as "VI Protected area with sustainable use of natural resources".
France Since 1861, the French Waters and Forests Military Agency (Administration des Eaux et Forêts) has strongly protected what was called the « artistic reserve » in Fontainebleau State Forest. With a total of 1,097 hectares, it is known as the first World nature reserve. Then in the 1950s, Integral Biological Reserves (Réserves Biologiques Intégrales, RBI) have been dedicated to a human free ecosystem evolution, in contrast to Managed Biological reserves (Réserves Biologiques Dirigées, RBD), where specific management practiced are applied to conserve vulnerable species or threatened habitats. Integral Biological Reserves occur in French State Forests or City Forests and are therefore managed by the
National Forests Office. In such reserves, all harvesting and hunting is forbidden except for exotic species elimination or track safety works to avoid fallen tree risk to visitors (already existing tracks in or on the edge of the reserve). At the end of 2014, there were 60 Integral Biological Reserves in French State Forests represented a total area of 111,082 hectares and ten in City Forests for a total of 2,835 hectares.
Greece In Greece there are some parks called "ethniki drimoi" (εθνικοί δρυμοί, national forests) that are under protection of the Greek government. Such parks include
Olympus,
Parnassos and
Parnitha National Parks.
New Zealand There are seven Wilderness Areas in New Zealand as defined by the
National Parks Act 1980 and the
Conservation Act 1987 that fall well within the IUCN definition. Wilderness areas cannot have any human intervention and can only have indigenous species re-introduced into the area if it is compatible with conservation management strategies. In
New Zealand wilderness areas are remote blocks of land that have high natural character. The
Conservation Act 1987 prevents any access by vehicles and livestock, the construction of tracks and buildings, and all indigenous natural resources are protected. They are generally over 400 km2 in size. Three Wilderness Areas are currently recognised, all on the
West Coast: Adams Wilderness Area, Hooker/Landsborough Wilderness Area and Paparoa Wilderness Area.
United States In the United States, a Wilderness Area is an area of federal land set aside by an
act of Congress. It is typically at least 5,000 acres (about 8 mi2 or 20 km2) in size. Human activities in wilderness areas are restricted to scientific study and non-mechanized recreation; horses are permitted but mechanized vehicles and equipment, such as cars and bicycles, are not. The United States was one of the first countries to officially designate land as "wilderness" through the
Wilderness Act of 1964. The Wilderness Act is an important part of wilderness designation because it created the legal definition of wilderness and established the National Wilderness Preservation System. The Wilderness Act defines wilderness as "an area where the earth and its community of life are untrammelled by man, where man himself is a visitor who does not remain." Wilderness designation helps preserve the natural state of the land and protects flora and fauna by prohibiting development and providing for non-mechanized recreation only. The first administratively protected wilderness area in the United States was the Gila National Forest. In 1922,
Aldo Leopold, then a ranking member of the U.S. Forest Service, proposed a new management strategy for the Gila National Forest. His proposal was adopted in 1924, and 750,000 acres of the Gila National Forest became the
Gila Wilderness.
The Great Swamp in New Jersey was the first formally designated wilderness refuge in the United States. It was declared a wildlife refuge on 3 November 1960. In 1966 it was declared a
National Natural Landmark and, in 1968, it was given wilderness status. Properties in the swamp had been acquired by a small group of residents of the area, who donated the assembled properties to the federal government as a park for perpetual protection. Today the refuge amounts to that are within thirty miles of
Manhattan. , in
New Mexico While wilderness designations were originally granted by an Act of Congress for Federal land that retained a "primeval character", meaning that it had not suffered from human habitation or development, the
Eastern Wilderness Act of 1975 extended the protection of the NWPS to areas in the eastern states that were not initially considered for inclusion in the Wilderness Act. This act allowed lands that did not meet the constraints of size, roadlessness, or human impact to be designated as wilderness areas under the belief that they could be returned to a "primeval" state through preservation. Approximately are designated as wilderness in the United States. This accounts for 4.82% of the country's total land area; however, 54% of that amount is found in Alaska (recreation and development in Alaskan wilderness is often less restrictive), while only 2.58% of the lower continental United States is designated as wilderness. As of 2023 there are
806 designated wilderness areas in the United States ranging in size from Florida's
Pelican Island at to Alaska's Wrangell-Saint Elias at . Several U.S. States have Wilderness Preservation systems that resemble the National Wilderness Preservation System. Notable among these are
California State Wilderness system, New York (Primarily in the
Adirondack Park), and
Maryland Wildland Preservation System.
Western Australia In Western Australia, a wilderness area is an area that has a wilderness quality rating of 12 or greater and meets a minimum size threshold of 80 km2 in temperate areas or 200 km2 in arid and tropical areas. A wilderness area is gazetted under section 62(1)(a) of the Conservation and Land Management Act 1984 by the Minister on any land that is vested in the Conservation Commission of Western Australia. ==International movement==
