A wilderness area
is a region where the land is in a natural state; where impacts from human activities are minimal—that is, as a wilderness
. It might also be called a wild
area. Especially in wealthier, industrialized nations, it has a specific legal meaning as well: as land where development is prohibited by law. Many nations have designated Wilderness Areas, including Australia
, New Zealand
, South Africa
and the United States
The World Conservation Union (IUCN) classifies wilderness at two levels, Ia (Strict Nature Preserves) and Ib (Wilderness areas).
Most scientists and conservationists agree that no place on earth is completely untouched by humanity, either due to past occupation by indigenous people, or through global processes such as climate change. Activities on the margins of specific wilderness areas, such as fire suppression and the interruption of animal migration also affect the interior of wildernesses.
Wilderness areas by country
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 the United States, a Wilderness Area is an area of federal land set aside by an act of Congress. Human activities in wilderness areas are restricted to scientific study and non-mechanized recreation; horses are permitted but motorized vehicles and equipment are not.
