Kaziranga National Park is known worldwide for its success in the conservation history of one horned Indian Rhinoceros. Playing host to a number of threatened species and migratory birds, it stands as a symbol of dedication for the conservation of endangered species animals and their habitat. With a UNESCO World Heritage Site status, it represents the single largest protected area in North East India, Assam. Spread over the Civil jurisdictions of Nagaon and Golaghat districts in Assam, the mighty Brahmaputra river flows to its North and to the South of it stands Karbi Anglong hills. Geographically, it is located between Longitude 92º50′ E & 93º 41′ E and Latitude 26º 30′N and 26º 50′ N. The entire Kaziranga National Park area was formed by the alluvial deposits of the Brahmaputra River and its smaller tributaries. The rivers carry a great amount of silt during the rainy season every year. The riverine area thus formed is colonised by saccharum and other grass species as soon as the landmasses are stabilized. But sometimes, before other tree species could take root on such landmasses, the landmass gets eroded. Probably numerous channels of the Brahmaputra river criss-crossing the entire area were once flowing through Kaziranga in the past and in course of time silt depositions and changing course of the Brahmaputra river formed into the ‘Beels’ (water bodies/ lakes) of various sizes and depth. This process of erosion and formation of landmasses are still going on along the Northern Boundary of Kaziranga National Park. Kaziranga National Park mainly comprises of the following four Forest Ranges. Although all of them come under Eastern Assam Wildlife Division, Bokakhat, from the viewpoint of Civil Administration jurisdiction, two of the Forest Ranges fall under Bokakhat Sub-Division in Golaghat District and other two fall under Kaliabor Sub-Division in Nagaon District. However, more areas are being added to the original Park area under both Golaghat and Nagaon District as well as Sonitpur District:
