Kaziranga, located in the Northeastern state of Assam in the flood plains of the Brahmaputra River’s south bank, was declared a World Heritage Site by UNESCO in 1985 for its unique natural environment. It was first established as a reserved forest in 1908 to protect the dwindling species of rhinoceros. It underwent several transformations over the years, as The Kaziranga Game Sanctuary in 1916, renamed Kaziranga Wildlife Sanctuary in 1950, and declared a national park in 1974. The park, which covers an area of 42,996 hectares (106,250 acres), has the distinction of being home to the largest population of the great Indian one-horned rhinoceros. There are many other mammals and birds species in the sanctuary.
