Category: Tiger

The magnificent, strong and charismatic Bengal Tiger is found primarily in India. It is the most numerous of all tiger subspecies, with more than 2,500^* left in the wild.

Small numbers of Bengals are also found in Bangladesh, Nepal, Bhutan, China and Myanmar.

Cat of the Month ~ April 2018

Since April 1973 The Bengal Tiger has been the national animal of both India and Bangladesh (so declared with the initiation of ‘Project Tiger’, a scheme to protect the tigers in India). Prior to this, the Lion was the national animal of India.

Project Tiger saw the creation of India’s many tiger reserves and helped to stabilize a serious decline in numbers. Sadly, poaching and loss of habitat are still major threats to this endagered feline.

It has been shown that the Bengal tiger arrived in the Indian subcontinent around 12,000 years ago, but it still ranks among the biggest wild cats alive today.

Male Bengals have an average total length of 270 to 310 cm including the tail, while females measure 240 to 265 cm on average. The tail is typically 85 to 110 cm long, and on average, tigers are 90 to 110 cm in height at the shoulders. The weight of males ranges from 180 to 258 kg (397 to 569 lb), while that of the females ranges from 100 to 160 kg (220 to 350 lb). Thus, the Bengal tiger rivals the Amur tiger in average weight. The smallest recorded weights for Bengal tigers are from the Bangladesh Sundarbans, where adult females are 75 to 80 kg (165 to 176 lb).

The tiger has exceptionally large teeth. Its canines are 7.5 to 10 cm long and are in fact the longest amongst all cats of the world.

In the Indian subcontinent, tigers inhabit tropical moist evergreen forests, tropical dry forests, moist deciduous forests, mangroves, subtropical and temperate upland forests and alluvial grasslands. Today, the best examples of this habitat type are limited to a few areas at the base of the outer foothills of the Himalayas including the Tiger Conservation Units (TCUs) of Rajaji-Corbett, Bardia-Banke, and the transboundary TCUs Chitwan-Parsa-Valmiki, Dudhwa-Kailali and Shuklaphanta-Kishanpur. Tiger densities in these TCUs are high, in part because of the extraordinary abundance of prey species available.

The Bengal tigers in the Sundarbans in India and Bangladesh are the only tigers in the world inhabiting mangrove forests. The population in the Indian Sundarbans is estimated as 70 tigers in total. In addition to the Indian and Bangladesh tiger populations, other notable populations are to be found in Bhutan and Nepal regions.

The basic social unit of the tiger is the elemental one of mother and offspring. Adult animals congregate only on an occasional and transitory basis when special conditions permit, such as plentiful supply of food. Otherwise they lead solitary lives, hunting individually for the dispersed forest and tall grassland prey animals. They establish and maintain home ranges but must always have access to other tigers (especially those of the opposite sex). Tigers sharing the same ground are well aware of each other’s movements and activities.

The tiger is a carnivore. It prefers hunting large ungulates such as chital, sambar, gaur, and to a lesser extent also barasingha, water buffalo, nilgai, serow and takin. Among the medium-sized prey species it frequently kills wild boar, and occasionally hog deer, muntjac and grey langur. Small prey species such as porcupine, hares and peafowl form a very small part in its diet. Because of the encroachment of humans into tiger habitat, it also preys on domestic livestock.

The nature of the tiger’s hunting method and prey availability results in a “feast or famine” feeding style: they often consume 18–40 kilograms (40–88 lb) of meat at one time.
Bengal tigers occasionally hunt and kill predators such as Indian leopard, Indian wolf, Indian jackal, fox, crocodiles, Asiatic black bear, sloth bear, and dhole. They rarely attack adult Indian elephant and Indian rhinoceros, but such extraordinarily rare events have been recorded. In Kaziranga National Park, tigers killed 20 rhinoceros in 2007. If injured, old or weak, or regular prey species are becoming scarce, tigers also attack humans and become man-eaters.

The tiger in India has no definite mating and birth seasons. Most young are born in December and April. Young have also been found in March, May, October and November. In the 1960s, certain aspects of tiger behaviour at Kanha National Park indicated that the peak of sexual activity was from November to about February, with some mating probably occurring throughout the year.

Males reach maturity at 4–5 years of age, and females at 3–4 years. A Bengal comes into heat at intervals of about 3–9 weeks, and is receptive for 3–6 days. After a gestation period of 104–106 days, 1–4 cubs are born in a shelter situated in tall grass, thick bush or in caves. Newborn cubs weigh 780 to 1,600 g (1.72 to 3.53 lb) and they have a thick wooly fur that is shed after 3.5–5 months. Their eyes and ears are closed. Their milk teeth start to erupt at about 2–3 weeks after birth, and are slowly replaced by permanent dentition from 8.5–9.5 weeks of age onwards. They suckle for 3–6 months, and begin to eat small amounts of solid food at about 2 months of age. At this time, they follow their mother on her hunting expeditions and begin to take part in hunting at 5–6 months of age. At the age of 2–3 years, they slowly start to separate from the family group and become transient — looking out for an area, where they can establish their own territory. Young males move further away from their mother’s territory than young females. Once the family group has split, the mother comes into heat again.

They occupied home ranges of 16 to 31 km2 (6.2 to 12.0 sq mi).
The home ranges occupied by adult male residents tend to be mutually exclusive, even though one of these residents may tolerate a transient or sub-adult male at least for a time. A male tiger keeps a large territory in order to include the home ranges of several females within its bounds.

Threats

Over the past century tiger numbers have fallen dramatically, with a decreasing population trend. None of the Tiger Conservation Landscapes within the Bengal tiger range is large enough to support an effective population size of 250 individuals. Habitat losses and the extremely large-scale incidences of poaching are serious threats to the species’ survival.

The most significant immediate threat to the existence of wild tiger 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.

The illicit demand for bones and body parts from wild tigers for use in Traditional Chinese medicine is the reason for the unrelenting poaching pressure on tigers on the Indian subcontinent. For at least a thousand years, tiger bones have been an ingredient in traditional medicines that are prescribed as a muscle strengthener and treatment for rheumatism and body pain.[69]

Human and tiger confrontations have been common on the Indian Subcontinent for many years. At the beginning of the 19th century tigers were so numerous it seemed to be a question as to whether man or tiger would survive. At this time it became the official policy to encourage the killing of tigers as rapidly as possible, rewards being paid for their destruction in many localities. In the latter half of the 19th century, marauding tigers began to take a toll of human life. These animals were pushed into marginal habitat, where tigers had formerly not been known, or where they existed only in very low density.

More recently in the Sundarbans region (for example), 10 out of 13 man-eaters recorded in the 1970s were males, and they accounted for 86% of the victims. These man-eaters have been grouped into the confirmed or dedicated ones who go hunting especially for human prey; and the opportunistic ones, who do not search for humans but will, if they encounter a man, attack, kill and devour him. Between 1999 and 2001, the highest concentration of tiger attacks on people occurred in the northern and western boundaries of the Bangladesh Sundarbans. Most people were attacked in the mornings while collecting fuel wood, timber, or other raw materials, or while fishing.

Conservation

The Bengal Tiger has been listed as Endangered on the IUCN Red List Since 2008. It is threatened by poaching, loss of its native habitat due to farming and by construction projects.
An area of special interest lies in the “Terai Arc Landscape” in the Himalayan foothills of northern India and southern Nepal, where 11 protected areas composed of dry forest foothills and tall-grass savannas harbor tigers in a 49,000 square kilometres (19,000 sq mi) landscape. The goals are to manage tigers as a single metapopulation, the dispersal of which between core refuges can help maintain genetic, demographic, and ecological integrity, and to ensure that species and habitat conservation becomes mainstreamed into the rural development agenda. In Nepal a community-based tourism model has been developed with a strong emphasis on sharing benefits with local people and on the regeneration of degraded forests. The approach has been successful in reducing poaching, restoring habitats, and creating a local constituency for conservation.

WWF partnered with Leonardo DiCaprio to form a global campaign, “Save Tigers Now”, with the ambitious goal of building political, financial and public support to double the wild tiger population by 2022.Save Tigers Now started its campaign in 12 different WWF Tiger priority landscapes, since May 2010.
