A national park is a nature park designated for conservation purposes because of unparalleled national natural, historic, or cultural significance. It is an area of natural, semi-natural, or developed land that is protected and owned by a government. Although governments hold different standards for national park designation, the conservation of 'wild nature' for posterity and as a symbol of national pride is a common motivation for the continued protection of all national parks around the world. National parks are almost always accessible to the public. Usually national parks are developed, owned and managed by national governments, though in some countries with federal or devolved forms of government, "national parks" may be the responsibility of subnational, regional, or local authorities.
The United States established Yellowstone National Park, the first "public park or pleasuring-ground for the benefit and enjoyment of the people," in 1872. Although Yellowstone was not officially termed a "national park" at the time, in practice it is widely held to be the first and oldest national park in the world. The Tobago Main Ridge Forest Reserve (in what is now Trinidad and Tobago; established in 1776) and the area surrounding Bogd Khan Uul Mountain (Mongolia, 1778), which were restricted from cultivation to protect surrounding farmland, are considered the oldest legally protected areas. Parks Canada, established on May 19, 1911, is the world's oldest national park service.
