The barasingha (Rucervus duvaucelii), also known as the swamp deer, is a deer species distributed in the Indian subcontinent. Populations in northern and central India are fragmented, and two isolated populations occur in southwestern Nepal. It has been extirpated in Pakistan and Bangladesh, and its presence is uncertain in Bhutan. [1]

Contents

The specific name commemorates the French naturalist Alfred Duvaucel. [3]

The swamp deer differs from all other Indian deer species in that the antlers carry more than three tines. Because of this distinctive character it is designated bārah-singgā, meaning "twelve-horned" in Hindi. [4] Mature stags usually have 10 to 14 tines, and some have been known to have up to 20. [5]

In Assamese, barasingha is called dolhorina; dol meaning swamp.

Characteristics

The barasingha is a large deer with a shoulder height of 44 to 46 in (110 to 120 cm) and a head-to-body length of nearly 6 ft (180 cm). Its hair is rather woolly and yellowish brown above but paler below, with white spots along the spine. The throat, belly, inside of the thighs and beneath the tail is white. In summer, the coat becomes bright rufous-brown. The neck is maned. Females are paler than males. Young are spotted. Average antlers measure 30 in (76 cm) round the curve with a girth of 5 in (13 cm) at mid beam. [6] A record antler measured 104.1 cm (41.0 in) round the curve. [5]

Stags weigh 170 to 280 kg (370 to 620 lb). Females are less heavy, weighing about 130 to 145 kg (287 to 320 lb). [7] Large stags have weighed from 460 to 570 lb (210 to 260 kg). [4]

Distribution and habitat

Swamp deer were common in many areas, including parts of the Upper Narmada valley and to the south in Bastar, during the 19th century. [6] They frequent flat or undulating grasslands and generally keep in the outskirts of forests. Sometimes, they are also found in open forest. [4]

In the 1960s, the total population was estimated at 1,600 to less than 2,150 individuals in India and about 1,600 in Nepal. Today, the distribution is much reduced and fragmented due to major losses in the 1930s–1960s following unregulated hunting and conversion of large tracts of grassland to cropland. Swamp deer occur in the Kanha National Park of Madhya Pradesh, in two localities in Assam, and in only 6 localities in Uttar Pradesh. They are regionally extinct in West Bengal. [8] They are also probably extinct in Arunachal Pradesh. [9] A few survive in Assam's Kaziranga and Manas National Parks. [10] [11] [12] [13] In 2005, a small population of about 320 individuals was discovered in the Jhilmil Jheel Conservation Reserve in Haridwar district in Uttarakhand on the east bank of the Ganges. This represents the northern limit of the species. [14] [15]

Distribution of subspecies

Three subspecies are currently recognized: [16]

Ecology and behaviour

Swamp deer are mainly grazers. [4] They largely feed on grasses and aquatic plants, foremost on Saccharum , Imperata cylindrica , Narenga porphyrocoma, Phragmites karka, Oryza rufipogon , Hygroryza and Hydrilla . They feed throughout the day with peaks during the mornings and late afternoons to evenings. In winter and monsoon, they drink water twice, and thrice or more in summer. In the hot season, they rest in the shade of trees during the day. [8]

In central India, the herds comprise on average about 8–20 individuals, with large herds of up to 60. There are twice as many females than males. During the rut they form large herds of adults. The breeding season lasts from September to April, and births occur after a gestation of 240–250 days in August to November. The peak is in September and October in Kanha National Park. [7] They give birth to single calves. [7]

When alarmed, they give out shrill, baying alarm calls. [5]

Compared to other deer species, Barasingha are more relaxed when it comes to guarding. They have fewer sentries and they spend most of their time grazing, unlike deer species like Spotted deer or Sambar deer. [22]

Threats

The swamp deer populations outside protected areas and seasonally migrating populations are threatened by poaching for antlers and meat, which are sold in local markets. Swamp deer lost most of its former range because wetlands were converted and used for agriculture so that suitable habitat was reduced to small and isolated fragments. [8] The remaining habitat in protected areas is threatened by the change in river dynamics, reduced water flow during summer, increasing siltation, and is further degraded by local people who cut grass, timber and fuelwood, [1] and by illegal farming on government land. [23]

George Schaller wrote: "Most of these remnants have or soon will have reached the point of no return." [7]

Conservation

Rucervus duvaucelii is listed on CITES Appendix I. [1] In India, it is included under Schedule I of the Wildlife Protection Act of 1972. [8]

In captivity

In 1992, there were about 50 individuals in five Indian zoos and 300 in various zoos in North America and Europe. [8]

Swamp deer were introduced to Texas. [24] They exist only in small numbers on ranches. [25]

In culture

Rudyard Kipling in The Second Jungle Book featured a barasingha in the chapter "The Miracle of Purun Bhagat" by the name of "barasingh". It befriends Purun Bhagat because the man rubs the stag's velvet off his horns. Purun Bhagat then gives the barasinga nights in the shrine at which he is staying, with his warm fire, along with a few fresh chestnuts every now and then. Later as pay, the stag warns Purun Bhagat and his town about how the mountain on which they live is crumbling.

Barasingha is the state animal of the Indian states of Madhya Pradesh and Uttar Pradesh. [26]

The Satpura Range is a range of hills in central India. The range rises in eastern Gujarat running east through the border of Maharashtra and Madhya Pradesh and ends in Chhattisgarh. The range parallels the Vindhya Range to the north, and these two east–west ranges divide Indian Subcontinent into the Indo-Gangetic plain of northern India and the Deccan Plateau of the south. The Narmada River originates from north-eastern end of Satpura in Amarkantak, and runs in the depression between the Satpura and Vindhya ranges, draining the northern slope of the Satpura range, running west towards the Arabian Sea. The Tapti River originates in the eastern-central part of Satpura, crossing the range in the center and running west at the range's southern slopes before meeting the Arabian Sea at Surat, draining the central and southern slopes of the range. Multai, the place of Tapi river origin is located about 465 kilometer far, south-westerly to Amarkantak, separated across by the hill range. The Godavari River and its tributaries drain the Deccan plateau, which lies south of the range, and the Mahanadi River drains the easternmost portion of the range. The Godavari and Mahanadi rivers flow into the Bay of Bengal. At its eastern end, the Satpura range meets the hills of the Chotanagpur Plateau. The Satpura Range is a horst mountain and is flanked by Narmada Graben in the north and much smaller but parallel Tapi Graben in the south.

<i>Rucervus</i> Genus of mammals belonging to the deer, muntjac, roe deer, reindeer, and moose family of ruminants

Rucervus is a genus of deer from India, Nepal, Indochina, and the Chinese island of Hainan. The only extant representatives, the barasingha or swamp deer and Eld's deer, are threatened by habitat loss and hunting; another species, Schomburgk’s deer, went extinct in 1938. Deer species found within the genus Rucervus are characterized by a specific antler structure, where the basal ramification is often supplemented with an additional small prong, and the middle tine is never present. The crown tines are inserted on the posterior side of the beam and may be bifurcated or fused into a small palmation.
