Indian leopard


The Indian leopard is a leopard subspecies widely distributed on the Indian subcontinent. The species Panthera pardus is listed as Vulnerable on the IUCN Red List because populations have declined following habitat loss and fragmentation, poaching for the illegal trade of skins and body parts, and persecution due to conflict situations.
The Indian leopard is one of the big cats occurring on the Indian subcontinent, apart from the Asiatic lion, Bengal tiger, snow leopard and clouded leopard.
In 2014, a national census of leopards around tiger habitats was carried out in India except the northeast. 7,910 individuals were estimated in surveyed areas and a national total of 12,000-14,000 speculated.

Taxonomy

Felis fusca was the scientific name proposed by Friedrich Albrecht Anton Meyer in 1794 who described a black leopard from Bengal that was on display at the Tower of London. Leopardus perniger proposed by Brian Houghton Hodgson in 1863 were five leopard skins from Nepal, out of which three were black. He mentioned Sikkim and Nepal as habitat.
Panthera pardus millardi proposed by Reginald Innes Pocock in 1930 was a single leopard skin and skull from Kashmir. It differed from typical P. p. fusca skins by longer hair and more greyish colour.
Since leopard populations in Nepal, Sikkim and Kashmir are not geographically isolated from leopard populations in the Indian subcontinent, they were subsumed to P. p. fusca in 1996.

Characteristics

The Indian leopard has strong legs and a long well-formed tail, broad muzzle, short ears and small, yellowish grey eyes, light grey ocular bulbs.
Its coat is spotted and rosetted on a pale yellow to yellowish-brown or golden background, except for the melanistic forms; the spots fade toward the white underbelly and the insides and lower parts of the legs. Rosettes are most prominent on the back, flanks and hindquarters. The pattern of the rosettes is unique to each individual. Juveniles have woolly fur, and appear dark due to the densely arranged spots. The white-tipped tail is long, white underneath, and displays rosettes, which form incomplete bands toward the end. The rosettes are larger in other leopard subspecies in Asia. Fur colour tends to be more pale and cream in arid habitats, more gray in colder climates, and of a darker golden hue in rainforest habitats.
The clouded leopard can be told apart by its diffuse "clouds" of spots compared to the smaller and distinct rosettes of the leopard, longer legs and thinner tail.

Skull

The largest skull recorded for an Indian leopard belonged to a large black panther in the area of Ootacamund, which was recorded in 1920. The panther was said to have bigger forelimbs and forequarters than hind-limbs and hind-quarters, and a skull and claws about as large as those of a tigress. The skull measured in basal length, and in breadth, and weighed. To compare, the skull of a West African panther measured in basal length, and in breadth, and weighed.

Size

Male Indian leopards grow to between and in body size with a to long tail and weigh between. Females are smaller, growing to between and in body size with a to long tail, and weigh between. Sexually dimorphic, males are larger and heavier than females.
The largest wild individual appears to have been a male man-eater that was shot in the Dhadhol area of Bilaspur district, Himachal Pradesh in 2016. It reportedly measured from head to tail, at the shoulder, and weighed.

Distribution and habitat

The Indian leopard is distributed in India, Nepal, Bhutan and parts of Pakistan.
Bangladesh has no viable leopard population but there are occasional sightings in the forests of Sylhet, Chittagong Hill Tracts and Cox's Bazar.
It inhabits tropical rainforests, dry deciduous forests, temperate forests and northern coniferous forests but does not occur in the mangrove forests of the Sundarbans.
It is thought that the Indus River in the west and the Himalayas in the north form topographical barriers to the dispersal of this subspecies. In the east, the Ganges Delta and the lower course of the Brahmaputra River are thought to form natural barriers to the range of the Indochinese leopard.
In southern Tibet, it was recorded in Qomolangma National Nature Preserve.
In Pakistan, it inhabits Himalayan forests and mountainous regions. In the 1970s, it was still recorded in the Kirthar Mountains, northeastern Baluchistan and Murree Hills. Since the turn of the century, leopards were recorded in and around Machiara National Park, Pir Lasora National Park, and Ayubia National Park. Leopards are occasionally spotted in the Margalla Hills in winter and are observed preying on monkeys in the woods as well as on local livestock. In April 2020, photos of three leopard families were taken by camera traps in the Margalla Hills.
In Nepal's Kanchenjunga Conservation Area, a melanistic leopard was photographed at an elevation of by a camera trap in May 2012.

Population in India

In 2015, 7,910 leopards were estimated to live in and around tiger habitat in India; about 12,000 to 14,000 leopards were speculated to live in the entire country. The following table gives the major leopard populations in the Indian states.

Ecology and behaviour

The leopard is elusive, solitary, and largely nocturnal. It is known for its ability in climbing, and has been observed resting on tree branches during the day, dragging its kills up trees and hanging them there, and descending from trees headfirst. It is a powerful swimmer, although is not as disposed to swimming as the tiger. It is very agile, and can run at over, leap over horizontally, and jump up to vertically. It produces a number of vocalizations, including grunts, roars, growls, meows, and purrs.
In Nepal's Bardia National Park, home ranges of male leopards comprised about, and of females about ; female home ranges decreased to when they had young cubs.
In Gir National Park, the home range of a male radio-collared leopard was estimated at. It killed prey once in 3.7 days.
The leopard is a versatile, opportunistic hunter, and has a very broad diet. It is able to take large prey due to its massive skull and powerful jaw muscles. In Sariska Tiger Reserve, the dietary spectrum of the Indian leopard includes axis deer, sambar deer, nilgai, wild boar, common langur, Indian hare and peafowl.
In Periyar Tiger Reserve, primates make up a large proportion of its diet.

Reproduction

Depending on the region, the leopard mates all year round. The estrous cycle lasts about 46 days and the female usually is in heat for 6–7 days. Gestation lasts for 90 to 105 days. Cubs are usually born in a litter of 2–4 cubs. Mortality of cubs is estimated at 41–50% during the first year. Females give birth in a cave, crevice among boulders, hollow tree, or thicket to make a den. Cubs are born with closed eyes, which open four to nine days after birth. The fur of the young tends to be longer and thicker than that of adults. Their pelage is also more gray in colour with less defined spots. Around three months of age, the young begin to follow the mother on hunts. At one year of age, leopard young can probably fend for themselves, but remain with the mother for 18–24 months. The average typical life span of a leopard is between 12 and 17 years.

Sympatric carnivores

Indian leopards are not common in habitats where tiger density is high, and are wedged between prime tiger habitat on the one side, and cultivated village land on the other. Where the tiger population is high or increasing, tigers drive leopards off to areas located closer to human settlements, like in Nepal's Bardia National Park and Sariska Tiger Reserve.
In Gujarat's Gir National Park, the Indian leopard is sympatric with the Asiatic lion. In the Himalayas, it co-occurs with the snow leopard up to an altitude of. They both hunt Himalayan tahr and musk deer, but the leopard usually prefers forested habitats located at lower altitudes than the snow leopard.
Elsewhere on the Indian subcontinent, the Indian leopard is sympatric with the clouded leopard, jungle cat, leopard cat and fishing cat.
It also shares habitat with the golden jackal, Indian fox, striped hyena, dhole, Indian wolf, sloth bear and Asian black bear.

Threats

Hunting of Indian leopards for the illegal wildlife trade is the biggest threat to their survival. They are also threatened by loss of habitat and fragmentation of formerly connected populations, and various levels of human–leopard conflict in human–dominated landscapes.
Several newspapers reported of leopards falling into open wells and being rescued with the help of Forest Department officials.

Poaching

A significant immediate threat to wild leopard populations is the illegal trade in poached skins and body parts between India, Nepal and China. The governments of these countries have failed to implement adequate enforcement response, and wildlife crime remained a low priority in terms of political commitment and investment for years. There are well-organised gangs of professional poachers, who move from place to place and set up camp in vulnerable areas. Skins are rough-cured in the field and handed over to dealers, who send them for further treatment to Indian tanning centres. Buyers choose the skins from dealers or tanneries and smuggle them through a complex interlinking network to markets outside India, mainly in China. Seized skins in Kathmandu confirm the city's role as a key staging point for illegal skins smuggled from India bound for Tibet and China.
It is likely that seizures represent a tiny fraction of the total illegal trade, with the majority of smuggled skins reaching their intended end market. Seizures revealed:
In May 2010, the Wildlife Protection Society of India estimated that in India at least 3,189 leopards were killed since 1994. For every tiger skin, there are at least seven leopard skins in the haul. Poaching for the illegal trade is suspected to have happened at a rate of at least four leopards per week during a 10-year period between 2002 and 2012.

Human–leopard conflict

Expansion of agriculturally used land, encroachment by humans and their livestock into protected areas are main factors contributing to habitat loss and decrease of wild prey. As a result, leopards approach human settlements, where they are tempted to prey on dogs, pigs and goats — domestic livestock, which constitutes an important part of their diet, if they live on the periphery of human habitations. Human–leopard conflict situations ensue, and have increased in recent years. In retaliation for attacks on livestock, leopards are shot, poisoned and trapped in snares. The leopards are considered to be unwanted trespassers by villagers. Conservationists criticize these actions, claiming that people are encroaching on the leopard's native habitat. India's Forest Department is entitled to set up traps only in cases of a leopard having attacked humans. If only the presence of a crowd of people prevents the leopard from escaping, then the crowd has to be dispersed and the animal allowed to escape.
As urban areas expanded, the natural habitats of leopards shrunk resulting in leopards venturing into urbanized areas due to easy access of domestic food sources.
Karnataka has a high number of such conflicts.
In recent years, leopards were sighted in Bangalore, and the forest department captured six leopards in the city's outskirts, relocated four of them to various other locations.
In and around the Shivalik hills of Himachal Pradesh, 68 leopards were killed by people between 2001 and 2013, of which 10 had been declared man-eaters.

Man-eating

The frequency of Leopard attacks on humans varies by geographical region and historical period. Attacks are regularly reported only in India and Nepal. Among the five "big cats", leopards are less likely to become man-eaters—only jaguars and snow leopards have a less fearsome reputation. While leopards generally avoid humans, they tolerate proximity to humans better than lions and tigers and often come into conflict with humans when raiding livestock.
Leopard attacks may have peaked in India during the late 19th and early 20th centuries, coinciding with rapid urbanization. Attacks in India are still relatively common, and in some regions of the country leopards kill more humans than all other large carnivores combined.
In Nepal, the rate of leopard predation on humans is estimated to be 16 times higher than anywhere else, resulting in approximately 1.9 human deaths annually per million inhabitants. Most attacks occur in the midland regions, i.e. in the Terai, midhills, and lesser Himalaya.
It is possible for humans to win a fight with a leopard, as in the case of a 56-year-old woman who killed an attacking leopard with a sickle and spade, and survived with heavy injuries. Globally, attacks on humans—especially nonfatal attacks that result in only minor injury—likely remain under-reported due to the lack of monitoring programs and standardized reporting protocol. Notable man-eaters include Leopard of Panar, Leopard of the Central Provinces, Leopard of Rudraprayag, Leopard of Gummalapur, Leopard of the Yellagiri Hills and Leopard of the Golis Range.

Conservation

Panthera pardus is listed in CITES Appendix I. Despite India and Nepal being contracting parties to CITES, national legislation of both countries does not incorporate and address the spirit and concerns of CITES. Trained human resources, basic facilities and effective networks for control of poaching and trade in wildlife are lacking.
Frederick Walter Champion was one of the first in India who after World War I advocated for the conservation of leopards, condemned sport hunting and recognised their key role in the ecosystem. Billy Arjan Singh championed their cause since the early 1970s.
There a few leopard rescue centres in India, such as the Manikdoh Leopard Rescue Centre in Junnar, but more rescue and rehabilitation centres are being planned. Some wildlife experts think that such centres are not an ideal solution, but that conflict resolution by way of changing human behaviour, land use or grazing patterns and implementing responsible forest management to lessen human-animal conflict would be far more effective to conserve leopards.
