The World Conservation Union (in English: World Conservation Union or International Union for Conservation of Nature and Natural Resources, abbreviated IUCN) is an international organization created to preserve natural values. It was founded in 1948 and is headquartered in Gland, Switzerland. 81 countries are members at the state level, but a government agency or non-governmental organization has joined it from a total of 145 countries, and 77 international organizations cooperate with it. Its main task is to encourage and help the preservation of biodiversity and the moderate use of natural resources, and the maintenance of ecological systems.
