The history of Kaziranga as a protected area can be traced back to 1904, when Mary Curzon, Baroness Curzon of Kedleston, the wife of the Viceroy of India, Lord Curzon of Kedleston, visited the area. After failing to see a single rhinoceros, for which the area was renowned, she persuaded her husband to take urgent measures to protect the dwindling species which he did by initiating planning for their protection. On 1 June 1905, the Kaziranga Proposed Reserve Forest was created.
Over the next three years, the park area was extended by 152 km, to the banks of the Brahmaputra River. In 1908, Kaziranga was designated a “Reserve Forest”. In 1916, it was re-designated the “Kaziranga Game Sanctuary” and remained so till 1938, when hunting was prohibited and visitors were permitted to enter the park.
The Kaziranga Game Sanctuary was renamed the “Kaziranga Wildlife Sanctuary” in 1950 by P. D. Stracey, the forest conservationist, in order to rid the name of hunting connotations. In 1954, the government of Assam passed the Assam (Rhinoceros) Bill, which imposed heavy penalties for rhinoceros poaching. Fourteen years later, in 1968, the state government passed the Assam National Park Act of 1968, declaring Kaziranga a designated national park. The 430 km park was given official status by the central government on 11 February 1974. In 1985, Kaziranga was declared a World Heritage Site by UNESCO for its unique natural environment.
Kaziranga has been the target of several natural and man-made calamities in recent decades. Floods caused by the overflow of the river Brahmaputra, leading to significant losses of animal life. Encroachment by people along the periphery has also led to a diminished forest cover and a loss of habitat. An ongoing separatist movement in Assam led by the United Liberation Front of Assam (ULFA) has crippled the economy of the region, but Kaziranga has remained unaffected by the movement; indeed, instances of rebels from the United Liberation Front of Assam protecting the animals and, in extreme cases, killing poachers, have been reported since the 1980s.
Some historians believe, however, that the name Kaziranga was derived from the Karbi word Kajir-a-rong, which means “the village of Kajir” (kajiror gaon). Among the Karbis, Kajir is a common name for a girl child, and it was believed that a woman named Kajir once ruled over the area. Fragments of monoliths associated with Karbi rule found scattered in the area seem to bear testimony to this assertion.
Kaziranga is one of the largest tracts of protected land in the sub-Himalayan belt, and due to the presence of highly diverse and visible species, has been described as a “biodiversity hotspot”. The park is located in the Indomalaya Eco zone, and the dominant biomes of the region are Brahmaputra Valley semi-evergreen forests of the tropical and subtropical moist broadleaf forests biome and a frequently flooded variant of the Terai-Duar savannah and grasslands of the tropical and subtropical grasslands, savannahs, and shrub lands biome. Kaziranga is also surrounded by lush green tea plantations, most of them contributing heavily to Assam’s economy.
