A park is a protected area, in its natural or semi-natural state, or planted, and set aside for human recreation and enjoyment, or for the protection of wildlife or natural habitats. It may consist of rocks, soil, water, flora and fauna and grass areas.
Wilderness parks are intact and undeveloped areas used mainly by wild species. Many parks are legally protected by law.
Protected wilderness zones are required for some wild species to survive. Some protected parks focus mainly on the survival of a few threatened species, such as gorillas or chimpanzees.
