UPSC CAPF – 2010
Bandipur National Park is *not* a World Heritage Site identified by UNESCO, whereas Kaziranga, Keoladeo, and Manas National Parks are.
Kaziranga National Park (Assam) was inscribed as a World Heritage Site in 1985, recognized for its unique natural environment and significant population of the Indian one-horned rhinoceros. Keoladeo National Park (Rajasthan), formerly Bharatpur Bird Sanctuary, was also inscribed in 1985 for its importance as a major wintering area for migratory birds. Manas Wildlife Sanctuary (Assam) was inscribed in 1985 and later relisted in 2011 after being on the list of World Heritage in Danger, recognized for its exceptional biodiversity. Bandipur National Park (Karnataka) is a well-known tiger reserve and part of the larger Nilgiri Biosphere Reserve, but it is not individually listed as a UNESCO World Heritage Site.
While Bandipur is not a World Heritage Site itself, the Nilgiri Biosphere Reserve, which includes Bandipur along with other protected areas, is part of the UNESCO World Network of Biosphere Reserves.
