Chitwan National Park is the first national park of Nepal. It was established in 1973 as the Royal Chitwan National Park and was granted the status of a World Heritage Site in 1984.[1] It covers an area of 952.63 km2 (367.81 sq mi) in the subtropical Inner Terai lowlands of south-central Nepal in Nawalpur, Chitwan, Makwanpur and Parsa Districts. It ranges in elevation from about 100 m (330 ft) in the river valleys to 815 m (2,674 ft) in the Sivalik Hills.[2]
In the north and west of the protected area the Narayani-Rapti river system forms a natural boundary to human settlements. Adjacent to the east of Chitwan National Park is Parsa National Park, contiguous in the south is the Indian Tiger Reserve Valmiki National Park. The coherent protected area of 2,075 km2 (801 sq mi) represents the Tiger Conservation Unit (TCU) Chitwan-Parsa-Valmiki, which covers a 3,549 km2 (1,370 sq mi) huge block of alluvial grasslands and subtropical moist deciduous forests.[3]
History
Since the end of the 19th century Chitwan – Heart of the Jungle – used to be a favorite hunting ground for Nepal's ruling class during the cool winter seasons. Until the 1950s, the journey from Kathmandu to Nepal's south was arduous as the area could only be reached by foot and took several weeks. Comfortable camps were set up for the feudal big game hunters and their entourage, where they stayed for a couple of months shooting hundreds of tigers, rhinoceroses, elephant, leopards and sloth bears.[4]
In 1950, Chitwan's forest and grasslands extended over more than 2,600 km2 (1,000 sq mi) and were home to about 800 rhinos. When poor farmers from the mid-hills moved to the Chitwan Valley in search of arable land, the area was subsequently opened for settlement, and poaching of wildlife became rampant. In 1957, the country's first conservation law inured to the protection of rhinos and their habitat. In 1959, Edward Pritchard Gee undertook a survey of the area, recommending creation of a protected area north of the Rapti River and of a wildlife sanctuary south of the river for a trial period of ten years.[5] After his subsequent survey of Chitwan in 1963, this time for both the Fauna Preservation Society and the International Union for Conservation of Nature, he recommended extension of the sanctuary to the south.[6]
By the end of the 1960s, 70% of Chitwan's jungles had been cleared, malaria eradicated using DDT, thousands of people had settled there, and only 95 rhinos remained. The dramatic decline of the rhino population and the extent of poaching prompted the government to institute the Gaida Gasti – a rhino reconnaissance patrol of 130 armed men and a network of guard posts all over Chitwan. To prevent the extinction of rhinos, the Chitwan National Park was gazetted in December 1970, with borders delineated the following year and established in 1973, initially encompassing an area of 544 km2 (210 sq mi).[7]
When the first protected areas were established in Chitwan, Tharu communities were forced to relocate from their traditional lands. They were denied any right to own land and thus forced into a situation of landlessness and poverty. When the national park was designated, Nepalese soldiers destroyed the villages located inside the boundary of the park, burning down houses and trampling fields using elephants. The Tharu people were forced to leave at gunpoint.[8]
In 1977, the park was enlarged to its present area of 952.63 km2 (367.81 sq mi). In 1997, a bufferzone of 766.1 km2 (295.8 sq mi) was added to the north and west of the Narayani-Rapti river system, and between the south-eastern boundary of the park and the international border to India.[2]
The park's headquarters is in Kasara. Close by the gharial and turtle conservation breeding centres have been established. In 2008, a vulture breeding centre was inaugurated aiming at holding up to 25 pairs of each of the two Gyps vultures species now critically endangered in Nepal - the Oriental white-backed vulture and the slender-billed vulture.
Climate
Chitwan has a humid subtropical monsoon influenced climate (Cwa) with high humidity all through the year.[4] The area is located in the central climatic zone of the Himalayas, where monsoon starts in mid June and eases off in late September. During these 14–15 weeks most of the 2,500 mm (98 in) annual precipitation falls. After mid-October, the monsoon clouds retreat, humidity drops off, and the top daily temperature gradually subsides from around 36 °C (97 °F) to 18 °C (64 °F). Nights cool down to 5 °C (41 °F) until late December, when it usually rains softly for a few days. Then temperatures start rising gradually.[citation needed]
The wide range of vegetation types in the Chitwan National Park is haunt of more than 700 species of wildlife and a not yet fully surveyed number of butterfly, moth and insect species. Apart from king cobra and rock python, 17 other species of snakes, starred tortoise and monitor lizards occur. The Narayani-Rapti river system, their small tributaries and myriads of oxbow lakes is habitat for 113 recorded species of fish and mugger crocodiles. In the early 1950s, about 235 gharials occurred in the Narayani River. The population has dramatically declined to only 38 wild gharials in 2003. Every year gharial eggs are collected along the rivers to be hatched in the breeding center of the Gharial Conservation Project, where animals are reared to an age of 6–9 years. Every year young gharials are reintroduced into the Narayani-Rapti river system, of which sadly only very few survive.[11]
Mammals
Chitwan National Park is home to 68 mammalspecies.[12] The "king of the jungle" is the Bengal tiger. The alluvial floodplain habitat of the Terai is one of the best tiger habitats anywhere in the world. Since the establishment of Chitwan National Park the initially small population of about 25 individuals increased to 70–110 in 1980. In some years this population has declined due to poaching and floods. In a long-term study carried out from 1995 to 2002 tiger researchers identified a relative abundance of 82 breeding tigers and a density of 6 females per 100 km2 (39 sq mi).[13] Information obtained from camera traps in 2010 and 2011 indicated that tiger density ranged between 4.44 and 6.35 individuals per 100 km2 (39 sq mi). They offset their temporal activity patterns to be much less active during the day when human activity peaked.[14]
Indian leopards are most prevalent on the peripheries of the park. They co-exist with tigers, but being socially subordinate are not common in prime tiger habitat.[15] In 1988, a clouded leopard (Neofelis nebulosa) was captured and radio-collared outside the protected area. It was released into the park, but did not stay there.[16]
Indian rhinoceros: since 1973 the population has recovered well and increased to 544 animals around the turn of the century. To ensure the survival of the endangered species in case of epidemics animals are translocated annually from Chitwan to the Bardia National Park and the Shuklaphanta National Park since 1986. However, the population has repeatedly been jeopardized by poaching: in 2002 alone, poachers killed 37 individuals in order to saw off and sell their valuable horns.[7] Chitwan has the largest population of Indian rhinoceros in Nepal, estimated at 605 of 645 individuals in total in the country as of 2015.[19]Gaurs spend most of the year in the less accessible Churia Hills in the south of the national park. But when the bush fires ease off in springtime and lush grasses start growing up again, they descend into the grassland and riverine forests to graze and browse. The Chitwan population of the world's largest wild cattle species has increased from 188 to 368 animals in the years 1997 to 2016. Furthermore, 112 animals were counted in the adjacent Parsa Wildlife Reserve. The animals move freely between these parks. Apart from numerous wild boars, there are also herds of chital, sambar, red muntjac and Indian hog deer that inhabits the park. Choushingas and Himalayan serows reside predominantly in the hills. Rhesus macaques, gray langurs, Indian pangolins, Indian crested porcupines, several species of flying squirrels, black-naped hares and endangered hispid hares are also present.[17]
Chitwan National Park received 18 wild water buffalo from Koshi Tappu Wildlife Reserve in 2016.[20]
Every year dedicated bird watchers and conservationists survey bird species occurring all over the country. In 2006 they recorded 543 species in the Chitwan National Park, much more than in any other protected area in Nepal and about two-thirds of Nepal's globally threatened species. Additionally, 20 black-chinned yuhina, a pair of Gould's sunbird, a pair of blossom-headed parakeet and one slaty-breasted rail, an uncommon winter visitor, were sighted in spring 2008.[21]
As soon as the winter visitors have left in spring, the summer visitors arrive from southern latitudes. The calls of cuckoos herald the start of spring. The colourful pitta and several sunbird species are common breeding visitors during monsoon. Among the many flycatcher species the Indian paradise flycatcher with his long undulating tail in flight is a spectacular sight.[citation needed]
