Inscription1985 (9th Session)

The national park was established on 10 March 1982. Previously the private duck shooting preserve of the Maharaja of Bharatpur since the 1850s, the area was designated as a bird sanctuary on 13 March 1976 and a Ramsar site under the Ramsar Convention in October 1981. [5]

Keoladeo Ghana National Park was made a World Heritage Site in 1985, under criterion iv. The justification provided was that the park is a "...wetland of international importance for migratory waterfowl. It is the wintering ground for the rare Siberian crane and habitat for large numbers of resident nesting birds". When the criteria were updated in 2005, the park fell under Criteria (x) which states that to be conferred the status of World Heritage, the site should "contain the most important and significant natural habitats for in-site conservation of biological diversity, including those containing threatened species of outstanding universal value from the point of view of science or conservation". [3]

Geography

Keoladeo National Park is 2 km (1.2 mi) south-east of Bharatpur and 55 km (34 mi) west of Agra. It is spread over approx 29 km2 (11 sq mi). One third of the Keoladeo National Park is wetland with mounds, dykes, and open water with or without submerged or emergent plants. The uplands have grasslands with tall grass species together with scattered trees and shrubs present in varying density. [5] A similar habitat with short grasses, such as Cynodon dactylon and Dichanthium annulatum also exists. Woodlands with thickets of huge Kadam trees Neolamarckia cadamba are distributed in scattered pockets. The park's flora consists of 379 species of flowering plants of which 96 are wetland species. The wetland is a part of the Indo-Gangetic Great Plains. [5]

Water remains only in some depressions. This alternate wetting and drying helps to maintain the ecology of the freshwater swamp, ideal for water-fowl and resident water birds. Arrangement to pump water from deep tube wells to fill small depressions to save seeds, spores and other aquatic life also exist. They are also helpful in extreme years of drought. [6]

Climate

During 1988, mean maximum temperature ranged from 20.9 °C (69.6 °F) in January to 47.8 °C (118.0 °F) in May, while the mean temperature varied from 6.8 °C (44.2 °F) in December to 26.5 °C (79.7 °F) in June. The diurnal temperature variation ranged from 5 °C (41 °F) in January to 50 °C (122 °F) in May. Mean relatively humidity varied from 62% in March to 83.3% in December. The mean annual precipitation is 662 mm (26.1 in), with rain falling on an average of 36 days per year. In 1988, only 395 mm (15.6 in) of rain fell during 32 days. [7]

Ecology

Flora

Piloo ( Salvadora oleoides and Salvadora persica ) are also present in the park, and happen to be virtually the only woody plants found thriving in areas of saline soil. Aquatic vegetation is also rich and provides a valuable food source for amphibious organisms. [8] In 2007 and 2008, several active attempts were made to eradicate the non-native mesquite Prosopis juliflora and some invasive members of the asteraceous genus Cineraria . [7]

Macro invertebrates such as worms, insects, and mollusks, though more abundant in variety and numbers than any other group of organisms, are present mostly in aquatic habitats. They are food for many fish and birds, as well as some animal species, and hence, constitute a major link in the food chain and functioning of the ecosystem. Land insects are in abundance and have a positive effect on the breeding of land birds.

Keoladeo National Park is an important wintering ground for large numbers of migrant birds; the most common waterfowl are gadwall, shoveler, common teal, cotton teal, tufted duck, knob-billed duck, bar-headed goose, little cormorant, great cormorant, Indian shag, ruff, painted stork, white spoonbill, Asian open-billed stork, oriental ibis, darter, common sandpiper, wood sandpiper, green sandpiper, greater flamingos, spot-billed pelican, great white pelican, demoiselle crane and sarus crane. [8]

More than 370 bird species have been recorded in Keoladeo National Park. Ornithologically, the park assumes significance in two respects: One because of its strategic location as a staging ground for migratory waterfowl arriving in the Indian subcontinent before dispersing to various regions. Further waterfowl converge here before departing to breeding grounds in the western Palearctic region. In addition, the wetland is a wintering area for the Siberian crane. Others birds present include warblers, Old World babblers, bee-eaters, bulbuls, buntings, chats, painted francolins and quails, Indian grey hornbill and Marshall's iora. Raptors include osprey, peregrine falcon, Pallas' sea eagle, short-toed eagle, tawny eagle, imperial eagle, spotted eagle and crested serpent eagle. The greater spotted eagle is breeding here. [8]

Mammalian fauna of Keoladeo National Park is equally rich with 27 identified species. Primates include rhesus macaque and Hanuman langur. [8] Ungulates are represented by nilgai, chital deer, sambar, blackbuck, Indian hog deer and wild boar.[ citation needed ]

Indian porcupine, small Indian mongoose and Indian gray mongoose are occasionally sighted. Cat species present jungle cat, leopard cat and fishing cat. Carnivores include Asian palm civet, small Indian civet, Bengal fox, golden jackals, striped hyena and smooth-coated otter. Many species of rats, mice, gerbils and bats also inhabit the park. [4]

Reptiles and amphibians

The herpetofauna of Keoladeo National Park is diverse. Out of the ten species of turtles in Rajasthan, seven are present in this park. Besides this, there are five lizard species including monitor lizard, thirteen snake species including pythons, krait, cobra and Russell's viper; seven species of amphibians include bullfrog and skipper frog occurring in the wetlands. [8]

Constraints

Some 2,500 cattle and domestic water buffalo were allowed in the area up until November 1982 when grazing was banned. Predictably, the ban led to a buildup of local resentment, resulting in an attempted forced entry into the park. Police opened fire and eight people were killed: tensions still remain high. [9] The absence of grazing is causing management problems as vegetation, principally Paspalum distichum, a perennial amphibious grass, blocks up the channels. The Rajasthan government has rejected a proposal from the Bombay Natural History Society to allow limited grazing, since this would conflict with the law. Furthermore, recycled nutrients from the large quantity of dung deposited by livestock probably supported considerable numbers of insects. [4]

The presence of some 700 feral cattle within the park is cause for concern as they compete with wildlife for valuable forage. Larvae of the Lepidopteran Parapoynx diminutalis has also been a serious pest, and considerably inhibited the growth of Nymphoides cristatum during June–July 1986. High levels of pollutants in Ajan Bund are believed to be responsible for the increasing number of piscivorous birds seen in a dazed state and unable to fly. Fewer birds were recorded in 1984 than in previous years. Four sarus cranes and 40 ring-necked doves were found dead outside the park during 1988 and early 1989, possibly due to pesticide poisoning, and a study of the impact of pesticide use in surrounding areas on the park has been initiated in addition to studies on heavy metal contamination. Disturbance from visitors can be a cause for concern, especially during December and January when visitors come to see the cranes. [10]

Scientific research and facilities

Between December 1992 and January 1995, a collaborative project between the Governments of India and Russia, International Crane Foundation and Wild Bird Society of Japan was set up to save the Siberian crane. The project focused on releasing captivity bred cranes into the wild, tracking migratory routes of common cranes, and building up the resident crane population in the park. Although the project did not yield the desired results, the successful survival of introduced cranes in the park has given sufficient hope to develop a viable resident population in the future. [10]

Crisis of 2007

A severe drought caused severe harm to the park and its flora and fauna in 2007. [11]

A proposal for water supply to Keoladeo National Park, Bharatpur was forwarded by the Government of Rajasthan seeking assistance from Planning Commission as advised and approved by the Ministry of Environment and Forests (MoEF) vide their letter dated 10.04.2008. As per the MoEF, the proposal is beyond the purview of the existing centrally sponsored scheme of the MoEF, seems to be viable and has the potential to put an end to the eternal water scarcity in Bharatpur National Park.

The Keoladeo National Park is a Ramsar Wetland Site and a World Heritage Site. Due to acute water scarcity, the ecosystem of the Park has been affected badly and this has resulted in reduction in the arrival of migratory birds in the National Park. Water supply is essential for the National Park, which is a wetland and a Ramsar site facing acute shortage of water for the last few years. Currently, apart from rainfall the Park receives water from "Ajan Bund", a temporary reservoir via the Dakan canal. Through a small canal dug last year water from Khokhar Weir (Bees Mora) is also available. The total requirement of water for the Park is estimated at 14.17 million cubic meters (500 MCft). The supply from Ajan Bund is irregular and subject to the bund being full to the extent of reservoir level at 8.5 meters. During the last several years either water is not supplied or supplied insufficiently. [4]

The project had been prepared to keep in view the need for 400 MCFT of water during late July to August, for a period of 30 days to the Park which is to be had by diverting and lifting flood waters of Yamuna. The project thus covered diversion of water during monsoon through underground pipes with lifting arrangements over a length of 16 km from the off-take point of Goverdhan drain near Santruk village. The estimated cost of the project as proposed by the State Government was to the tune of Rs. 650 million. The project proposed was to channelize water from Govardhan drain to meet the water deficit of KNP during the months of July to September at the time of requirement. The major components of the project were construction of a head regulator with control gate at the drain located in the state, raw water reservoir with capacity of 13,000 m, 3 pump houses, DG sets for pumping station and laying and testing of /PCC/MS pipelines.

The Kanwar Taal or Kabar Taal Lake or Kabartal Wetland located in Begusarai district of Bihar, India, is Asia's largest freshwater oxbow lake. It is approximately six times the size of the Bharatpur Sanctuary. In November 2020, the Ministry of Environment, Forest and Climate Change (MoEFCC) declared it the first Ramsar site in Bihar. There are a total of 85 Ramsar Sites in India till 2024.
Kanwar jheel, as it is locally called, is located 22 km north-west of Begusarai Town in Manjhaul. It is a residual oxbow lake, formed due to meandering of Burhi Gandak river, a tributary of Ganga, in the geological past. It covers 2,620 hectares of the Indo-Gangetic plains in the northern Bihar State. The Site is one of 18 wetlands within an extensive floodplain complex; it floods during the monsoon season to a depth of 1.5 metres. This absorption of floodwaters is a vital service in Bihar State where 70% of the land is vulnerable to inundation. During the dry season, areas of marshland dry out and are used for agriculture. Significant biodiversity is present, with 165 plant species and 394 animal species recorded, including 221 bird species. The Wetland is an important stopover along the Central Asian Flyway, with 58 migratory waterbirds using it to rest and refuel. It is also a valuable site for fish biodiversity with over 50 species documented. Five critically endangered species inhabit the site, including three vultures – the red-headed vulture, white-rumped vulture and Indian vulture – and two waterbirds, the sociable lapwing and Baer’s pochard. Major threats to the Site include water management activities such as drainage, water abstraction, damming and canalization.
