A willife refuge may be a naturally-occurring sanctuary, such as an island, that provides protection for species from hunting, predation or competition. 'Wildlife Refuge' is also one of the many titles given to protected areas, and refers to a geographic territory within which wildlife is protected which is also commonly known as Wildlife Sanctuary . Such wildlife refuges are generally officially designated territories, created by government legislation, though the land itself may be publicly or privately owned. Also, the Chernobyl nuclear accident site has also accidentally become a wildlife refuge.
