Kaziranga National Park (Assamese: কাজিৰঙা ৰাষ্ট্ৰীয় উদ্যান, Kazirônga Rastriyô Uddyan, Шаблон:IPA-as) is an Indian national park and a World Heritage Site in Golaghat and Nagaon districts of Assam, India. It is refuge for the world's largest population of Great One-horned Rhinoceros. The park has many Elephant, Water Buffalo and Swamp Deer. It is recognized as an Important Bird Area by Birdlife International for conservation of avifaunal species. The park has achieved notable progress in wildlife conservation despite several constraints.
Kaziranga is a vast stretch of tall elephant grass, marshland and dense tropical moist broadleaf forests crisscrossed by four main rivers — Brahmaputra, Diphlu, Mora Diphlu and Mora Dhansiri and has numerous small water bodies. Kaziranga has been the theme of several books, documentaries and songs. The park celebrated its centenary in 2005 since its establishment in 1905 as a reserve forest.
Geography
The park is located between latitude 26°30 N to 26°45 N and longitude 93°08 E to 93°36 E in the Kaliabor subdivision of the Nagaon district and the Bokakhat subdivision of the Golaghat district, in the state of Assam in India.[1] It is roughly Шаблон:Convert long and Шаблон:Convert wide, with an area of 378.22 km², having lost around 51.14 km² to erosion by the Brahmaputra.[2] A total addition of Шаблон:Convert along the present boundary of the park has been made and notified with separate national park status to provide extended habitat for increasing population of wildlife or as a corridor for safe movement of animals to Karbi Anglong Hills.[1] Шаблон:Rp
The southern border of the park is roughly defined by the Mora Diphlu river. Further south are the hills of Barail and the Mikir. The National Highway NH-37 was once the formal southern boundary of the park.[1] The Brahmaputra River constitutes the dynamically changing Northern boundary of the park. The other rivers in Kaziranga are Diphlu, Mora Diphlu and Mora Dhansiri.[3] Kaziranga is mostly flat expanses of fertile alluvial silt (part of the highly fertile Middle Brahmaputra alluvial flood plains),[1] exposed sandbars, riverine flood-formed lakes called Beels (Beels make up as much as 5% of the surface area)[1] and elevated flats called chapories where animals shelter during floods. Many artificial chapories have been built with the help of the Indian Army.[4][5] The average altitude of the park ranges from Шаблон:Convert to Шаблон:Convert,[1] with the Mikir Hills to the south of the park rising to around Шаблон:Convert.[1]
Human habitation
There are no villages within the boundary of the park. However the area outside the boundary of the park is very densely populated. There were 39 villages within a Шаблон:Convert radius of the park, with an estimated population of 22,300 people in 1983–1984.[1] According to a 2002 report, the figure has risen by 184 villages with about 50,000 households.[3] A few new settlements have come up in recent times outside the park borders for servicing the booming eco-tourism industry.[3]
Geology
Per the plate tectonics, Assam is in the easternmost projection of the Indian Plate, where it is thrusting underneath the Eurasian Plate creating a subduction zone. It is postulated that due to the northeasterly movement of the Indian plate, the sediment layers of an ancient geosyncline called Tethys (in between Indian and Eurasian Plates) have been pushed upward to form the Himalayas mountain range.[6] Karbi Anglong plateau, which is situated to the south of the Kaziranga (along with the Khasi and Garo Hills) is originally part of the South Indian Plateau system. It is believed that due to the force exerted by the north-eastwardly movement of the Indian plate at the time of the Himalayan origin, a huge fault was created between the Rajmahal hills and the Karbi-Meghalaya plateau. Later, this depression was filled up by the depositional activity of numerous rivers. Today the Maghalaya and Karbi Anglong plateau remains detached from the main Peninsular block. Average height of this plateau varies from Шаблон:Convert to Шаблон:Convert.[7]
Kaziranga National Park's landscape is the creation of natural forces of silt deposition and erosion that has been effected by the river Brahmaputra over hundreds of years. This ongoing process of erosion and deposition becomes more severe during the floods which occur at regular intervals during the monsoon season.[3] The Brahmaputra river in its Шаблон:Convert flow through Assam receives more than a hundred tributaries flowing down from the adjoining hills. Once the tributaries hit the river valley, they lose their momentum; deposit the silt they carry, form ox-bow lakes and alluvial fans and branch out before picking up their courses again to join the Brahmaputra.[8]
Biomes
Kaziranga is one of the largest tracts of protected land in the sub-Himalayan belt, and due to its high species diversity and presence of high-visibility species, has been described as a "biodiversity hotspot".[9]
The park is located in the Indomalayan realm, and the region falls in two ecoregions, the Brahmaputra Valley semi-evergreen forests of the Tropical and subtropical moist broadleaf forests biome, and a frequently flooded variant of the Terai-Duar savanna and grasslands of the Tropical and subtropical grasslands, savannas, and shrublands biome.Шаблон:Citation needed
