moreThe modern idea that species and habitats should be protected by legislation has its origins in measures to control access to and to preserve game, and was well established in British and other colonies by the end of the nineteenth century. Preservationists were inspired by the example of Yellowstone (1872) and other national parks in the United States, as well as by the extensive network of forest reserves in India and similar models of territorial protection. As the twentieth century progressed, increasing numbers of parks and reserves were gazetted in countries around the world, often combining the conservation of flora and fauna with the generation of revenues from tourism and other sources. The growth of environmentalism and the institution of a global conservation regime by the United Nations after the end of World War II stimulated the further proliferation of protected areas, a pattern boosted in recent decades by the development of community-based and other modes of decentralized governance (Adams 2004). The world's conservation estate continues to expand and evolve: the 2014 United Nations List of Protected Areas included information on 209,429 designated terrestrial and marine protected areas, covering a total of 32,868,673 square kilometers, equivalent to 17.4 percent of the earth's surface (Deguignet et al. 2014).
