The TCUs in tropical moist evergreen forests represent the less common tiger habitats, being largely limited to the upland areas and wetter parts of the Western Ghats, and include the Tiger Reserves of Periyar, Kalakad-Mundathurai, Bandipur and Parambikulam Wildlife Sanctuary.
The methodology used during the tiger census of 2008 extrapolates site-specific densities of tigers, their co-predators and prey derived from camera trap and sign surveys using GIS. Based on the result of these surveys, the total tiger population has been estimated at 1,411 individuals ranging from 1,165 to 1,657 adult and sub-adult tigers of more than 1.5 years of age. The following six landscape complexes comprising several ecological landscapes were surveyed across India based on current tiger occupancy and potential for connectivity:
- in the Shivaliks–Gangetic flood plain landscape there are six populations with an estimated population size of 259 to 335 individuals occupying 5,080 বৰ্গ কি.মি.s (1,960 বৰ্গ মাইল) of forested habitats, which are located in Rajaji and Corbett national parks, in the connected habitats of Dudhwa-Kheri-Pilibhit, in Suhelwa Tiger Reserve, in Sohagi Barwa Sanctuary and in Valmiki National Park;
- in the Central Indian highlands there are 17 populations with an estimated population size of 437 to 661 individuals occupying 48,610 বৰ্গ কি.মি.s (18,770 বৰ্গ মাইল) of forested habitats, which are located in the landscapes of Kanha-Pench, Satpura-Melghat, Sanjay-Palamau, Navegaon-Indravati; isolated populations are supported in the tiger reserves of Bandhavgarh, Tadoba, Simlipal and the national parks of Panna, Ranthambore–Kuno–Palpur–Madhav and Saranda;
- in the Eastern Ghats landscape there is a single population with an estimated population size of 49 to 57 individuals occupying 7,772 বৰ্গ কি.মি.s (3,001 বৰ্গ মাইল) of habitat in three separate forest blocks located in the Srivenkateshwara National Park, Nagarjunasagar Tiger Reserve and the adjacent proposed Gundla Brahmeshwara National Park, and forest patches in the tehsils of Kanigiri, Baduel, Udayagiri and Giddalur;
- in the Western Ghats landscape there are seven populations with an estimated population size of 336 to 487 individuals occupying 21,435 বৰ্গ কি.মি.s (8,276 বৰ্গ মাইল) forest in three major landscape units;
- in the Brahmaputra flood plains and north-eastern hills tigers occupy 4,230 বৰ্গ কি.মি.s (1,630 বৰ্গ মাইল) in several patchy and fragmented forests;
- in the Indian Sundarbans tigers occupy about 1,586 বৰ্গ কি.মি.s (612 বৰ্গ মাইল) of mangrove forest.
In May 2008, forest officials spotted 14 tiger cubs in Rajasthan's Ranthambore National Park. In June 2008, a tiger from Ranthambore was relocated to Sariska Tiger Reserve, where all tigers had fallen victim to poachers and human encroachments since 2005.
Tigers in Bangladesh are now relegated to the forests of the Sundarbans and the Chittagong Hill Tracts. The Chittagong forest is contiguous with tiger habitat in India and Myanmar, but the tiger population is of unknown status.
As of 2004, population estimates in Bangladesh ranged from 200 to 419, mostly in the Sunderbans. This region is the only mangrove habitat in this bioregion, where tigers survive, swimming between islands in the delta to hunt prey. Bangladesh's Forest Department is raising mangrove plantations supplying forage for spotted deer. Since 2001, afforestation has continued on a small scale in newly accreted lands and islands of the Sundarbans.
The tiger population in the Terai of Nepal is split into three isolated subpopulations that are separated by cultivation and densely settled habitat. The largest population lives in Chitwan National Park and in the adjacent Parsa Wildlife Reserve encompassing an area of 2,543 বৰ্গ কি.মি. (982 বৰ্গ মাইল) of prime lowland forest. To the west, the Chitwan population is isolated from the one in Bardia National Park and adjacent unprotected habitat further west, extending to within 15 km (9.3 মাইল) of the Sukla Phanta Wildlife Reserve, which harbours the smallest population. The bottleneck between the Chitwan-Parsa and Bardia-Sukla Phanta metapopulations is situated just north of the town of Butwal.
As of 2005, the population in Bhutan is estimated at 67–81 individuals. Tigers occur from an altitude of 200 মিটাৰ (660 ফুট) in the subtropical Himalayan foothills in the south along the border with India to over 3,000 মিটাৰ (9,800 ফুট) in the temperate forests in the north, and are known from 17 of 18 districts. Their stronghold appears to be the central belt of the country ranging in altitude between সাঁচ:Convert/and/AonSoff (সাঁচ:Convert/and/AonSoff), between the Mo River in the west and the Kulong River in the east. In 2010, camera traps recorded a pair of tigers at altitudes of 3,000 to 4,100 মিটাৰ (9,800 to 13,000 ফুট). The male was recorded scent-marking, and the female can also be seen to be lactating, confirming that the pair are living within their own territory, and strongly suggesting they are breeding at that altitude.
The basic social unit of the tiger is the elemental one of mother and offspring. Adult animals congregate only on an ad hoc 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 animals, upon which they prey. They establish and maintain home ranges. Resident adults of either sex tend to confine their movements to a definite area of habitat within which they satisfy their needs, and in the case of tigresses, those of their growing cubs. Besides providing the requirements of an adequate food supply, sufficient water and shelter, and a modicum of peace and seclusion, this location must make it possible for the resident to maintain contact with other tigers, especially those of the opposite sex. Those sharing the same ground are well aware of each other’s movements and activities.
In the Panna Tiger Reserve an adult radio-collared male tiger moved 1.7 to 10.5 km (1.1 to 6.5 মাইল) between locations on successive days in winter, and 1 to 13.9 km (0.62 to 8.6 মাইল) in summer. His home range was about 200 বৰ্গ কি.মি. (77 বৰ্গ মাইল) in summer and 110 বৰ্গ কি.মি. (42 বৰ্গ মাইল) in winter. Included in his home range were the much smaller home ranges of two females, a tigress with cubs and a sub-adult tigress. They occupied home ranges of 16 to 31 বৰ্গ কি.মি. (6.2 to 12 বৰ্গ মাইল).
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, so that he may maintain mating rights with them. Spacing among females is less complete. Typically there is partial overlap with neighbouring female residents. They tend to have core areas, which are more exclusive, at least for most of the time. Home ranges of both males and females are not stable. The shift or alteration of a home range by one animal is correlated with a shift of another. Shifts from less suitable habitat to better ones are made by animals that are already resident. New animals become residents only as vacancies occur when a former resident moves out or dies. There are more places for resident females than for resident males.
Tigers are carnivores. They prefer 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 they frequently kill wild boar, and occasionally hog deer, muntjac and Gray langur. Small prey species such as porcupines, hares and peafowl form a very small part in their diet. Due to the encroachment of humans into their habitat, they also prey on domestic livestock.
In most cases, tigers approach their victim from the side or behind from as close a distance as possible and grasp the prey's throat to kill it. Then they drag the carcass into cover, occasionally over several hundred meters, to consume it. The nature of the tiger's hunting method and prey availability results in a "feast or famine" feeding style: they often consume 18–40 কিলোগ্ৰামs (40–88 পাউণ্ড) of meat at one time.
Bengal tigers have been known to take other predators, such as leopards, wolves, jackals, foxes, crocodiles, Asiatic black bears, sloth bears, and dholes as prey, although these predators are not typically a part of their diet. Adult elephants and rhinoceroses are too large to be successfully tackled by tigers, but such extraordinarily rare events have been recorded. The Indian hunter and naturalist Jim Corbett described an incident in which two tigers fought and killed a large bull elephant. If injured, old or weak, or their normal prey is becoming scarce, they may even 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 tigress 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 (1.7 to 3.5 পাউণ্ড) 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.
প্ৰধান সংকট[সম্পাদনা কৰক]
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 challenge in the Western Ghats forest complex in western South India, an area of 14,400 বৰ্গ মাইলs (37,000 বৰ্গ কি.মি.) stretching across several protected areas is that people literally live on top of the wildlife. The Save the Tiger Fund Council estimates that 7,500 landless people live illegally inside the boundaries of the 386 বৰ্গ মাইল (1,000 বৰ্গ কি.মি.) Nagarhole National Park in southwestern India. A voluntary if controversial resettlement is underway with the aid of the Karnataka Tiger Conservation Project led by K. Ullas Karanth of the Wildlife Conservation Society.[উদ্ধৃতিৰ প্ৰয়োজন]
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. Buyers choose the skins from dealers or tanneries and smuggle them through a complex interlinking network to markets outside India, mainly in China. Other factors contributing to their loss are urbanization and revenge killing. Farmers blame tigers for killing cattle and shoot them. Their skins and body parts may however become a part of the illegal trade.
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.
Between 1994 and 2009, the Wildlife Protection Society of India has documented 893 cases of tigers killed in India, which is just a fraction of the actual poaching and trade in tiger parts during those years.
In 2006, India's Sariska Tiger Reserve lost all of its 26 tigers, mostly to poaching. In 2007, police in Allahabad raided a meeting of suspected poachers, traders and couriers. One of the arrested persons was the biggest buyer of tiger parts in India who used to sell them off to the Chinese traditional medicinal market, using women from a nomadic tribe as couriers. In 2009, none of the 24 tigers residing in the Panna Tiger Reserve were left due to excessive poaching. In November 2011, two tigers were found dead in Maharashtra: a male tiger was trapped and killed in a wire snare; a tigress died of electrocution after chewing at an electric cable supplying power to a water pump; another tigress was found dead in Kanha Tiger Reserve landscape — poisoning is suspected to be the cause of her death.
ঢেঁকীয়াপতীয়া বাঘৰ মানুহৰ সৈতে সংঘাত[সম্পাদনা কৰক]
The Indian subcontinent has served as a stage for intense human and tiger confrontations. The region affording habitat where tigers have achieved their highest densities is also one which has housed one of the most concentrated and rapidly expanding human populations. 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. It became the official policy to encourage the killing of tigers as rapidly as possible, rewards being paid for their destruction in many localities. The United Provinces supported large numbers of tigers in the submontane Terai region, where man-eating had been uncommon. 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, by an expanding population of more vigorous animals that occupied the prime habitat in the lowlands, where there was high prey density and good habitat for reproduction. The dispersers had no where else to go, since the prime habitat was bordered in the south by cultivation. They are thought to have followed back the herds of domestic livestock that wintered in the plains when they returned to the hills in the spring, and then being left without prey when the herds dispersed back to their respective villages. These tigers were the old, the young and the disabled. All suffered from some disability, mainly caused either by gunshot wounds or porcupine quills.
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 comprising dry forest foothills and tall-grass savannas harbor tigers in a 49,000 বৰ্গ কি.মি.s (19,000 বৰ্গ মাইল) 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.
In 1972, Project Tiger was launched aiming at ensuring a viable population of tigers in the country and preserving areas of biological importance as a natural heritage for the people. The project's task force visualised these tiger reserves as breeding nuclei, from which surplus animals would emigrate to adjacent forests. The selection of areas for the reserves represented as close as possible the diversity of ecosystems across the tiger's distribution in the country. Funds and commitment were mustered to support the intensive program of habitat protection and rehabilitation under the project. By the late 1980s, the initial nine reserves covering an area of 9,115 বৰ্গ কি.মি.s (3,519 বৰ্গ মাইল) had been increased to 15 reserves covering an area of 24,700 বৰ্গ কি.মি.s (9,500 বৰ্গ মাইল). More than 1100 tigers were estimated to inhabit the reserves by 1984.
Through this initiative the population decline was reversed initially, but has resumed in recent years; India's tiger population decreased from 3,642 in the 1990s to just over 1,400 from 2002 to 2008.
The Indian Wildlife Protection Act of 1972 enables government agencies to take strict measures so as to ensure the conservation of the Bengal tigers. The Wildlife Institute of India estimates showed that tiger numbers had fallen in Madhya Pradesh by 61%, Maharashtra by 57%, and Rajasthan by 40%. The government's first tiger census, conducted under the Project Tiger initiative begun in 1973, counted 1,827 tigers in the country that year. Using that methodology, the government observed a steady population increase, reaching 3,700 tigers in 2002. However, the use of more reliable and independent censusing technology (including camera traps) for the 2007–2008 all-India census has shown that the numbers were in fact less than half than originally claimed by the Forest Department.
Following the revelation that only 1,411 Bengal tigers exist in the wild in India, down from 3,600 in 2003, the Indian government has decided to set up eight new tiger reserves. Because of dwindling tiger numbers, the Indian government has pledged US$153 million to further fund the Project Tiger initiative, set-up a Tiger Protection Force to combat poachers, and fund the relocation of up to 200,000 villagers to minimize human-tiger interaction.

Bengal tigers have been captive bred since 1880 and widely crossed with other tiger subspecies. Indian zoos have bred tigers for the first time being at the Alipore Zoo in Kolkata. The 1997 International Tiger Studbook lists the global captive population of Bengal tigers at 210 individuals that are all kept in Indian zoos, except for one female in North America. Completion of the Indian Bengal Tiger Studbook is a necessary prerequisite to establishing a captive management program for tigers in India.
The tiger is one of the animals displayed on the Pashupati seal of the Indus Valley Civilisation. The tiger crest is the emblem on the Chola coins. The seals of several Chola copper coins show the tiger, the Pandya emblem fish and the Chera emblem bow, indicating that the Cholas had achieved political supremacy over the latter two dynasties. Gold coins found in Kavilayadavalli in the Nellore district of Andra Pradesh have motifs of the tiger, bow and some indistinct marks.
