Wilderness or wildland is a natural environment on Earth which has not been much disturbed by humans.
Wilderness areas can be found in reserves, estates, farms, conservation areas, ranches, National Forests, National Parks and even in urban areas along rivers, gulches or any undeveloped areas. These areas are important for the survival of species, biodiversity, ecology, conservation, solitude, and recreation.
Wilderness is deeply valued for cultural, spiritual, moral, and aesthetic reasons. Some nature writers believe wilderness areas are vital for the human spirit and creativity.
