The '''Bengal tiger''' or '''Royal Bengal tiger''' is a [[population]] of the ''[[Panthera tigris tigris]]'' subspecies and the nominate tiger subspecies. It ranks among the biggest wild cats alive today. It is estimated to have been present in the [[Indian subcontinent]] since the [[Late Pleistocene]] for about 12,000 to 16,500 years. Its historical range covered the [[Indus River]] valley until the early 19th century, almost all of [[India]], western [[Pakistan]], southern [[Nepal]], [[Bangladesh]], [[Bhutan]] and southwestern [[China]]. Today, it inhabits India, Bangladesh, Nepal, Bhutan, and southwestern China. It is threatened by [[poaching]], [[habitat loss]] and [[habitat fragmentation]].

As of 2022, the Bengal tiger population was estimated at 3,167–3,682 individuals in India, 316–355 individuals in Nepal, 131 individuals in Bhutan and around 114 individuals in Bangladesh.

==Taxonomy==
''Felis tigris'' was the [[scientific name]] used by [[Carl Linnaeus]] in 1758 for the tiger.<ref name="Linn1758">{{Cite book |author=Linnaeus, C. |year=1758 |title=Caroli Linnæi Systema naturæ per regna tria naturæ, secundum classes, ordines, genera, species, cum characteribus, differentiis, synonymis, locis.

The [[Valid name (zoology)|validity]] of several tiger subspecies in continental Asia was questioned in 1999. [[Morphology (biology)|Morphologically]], tigers from different regions vary little, and [[gene flow]] between populations in those regions is considered to have been possible during the [[Pleistocene]]. Therefore, it was proposed to recognise only two subspecies as valid, namely ''P. t. tigris'' in mainland Asia, and [[Javan tiger|''P. t. sondaica'']] in the [[Greater Sunda Islands]] and possibly in [[Sundaland]].<ref name=Kitchener1999>{{Cite book |last=Kitchener |first=A. |title=Riding the Tiger: Tiger Conservation in Human-Dominated Landscapes |date=1999 |publisher=Cambridge University Press |isbn=978-0-521-64835-6 |editor1-last=Seidensticker |editor1-first=J. |pages=19–39 |chapter=Tiger distribution, phenotypic variation and conservation issues |editor2-last=Christie |editor2-first=S. |editor3-last=Jackson |editor3-first=P. |chapter-url=http://www.nfwf.org/AM/Template.cfm?Section=Home&CONTENTID=3060&TEMPLATE=/CM/ContentDisplay.cfm |archive-url=https://web.archive.org/web/20120423162028/http://www.nfwf.org/AM/Template.cfm?Section=Home |archive-date=23 April 2012 |url-status=dead}}</ref> The [[nominate subspecies]] ''P. t. tigris'' constitutes two [[clade]]s: the northern clade comprises the Siberian and Caspian tiger populations, and the southern clade all remaining continental tiger populations.<ref>{{Cite journal |title=Planning tiger recovery: Understanding intraspecific variation for effective conservation |last1=Wilting |first1=A. |last2=Courtiol |first2=A. |first3=P. |last3=Christiansen |first4=J. |last4=Niedballa |first5=A.

===Genetic ancestry===
The Bengal tiger is defined by three distinct [[mitochondrial]] [[nucleotide]] sites and 12 unique [[Microsatellite (genetics)|microsatellite]] alleles.

==Characteristics==
[[File:Tiger facial marking Sultan (T72) Ranthambhore India 12.10.2014.jpg|thumb|Facial close up of a male tiger]]
The Bengal tiger's coat is yellow to light orange, with stripes ranging from dark brown to black; the belly and the interior parts of the limbs are white, and the tail is orange with black rings. The [[white tiger]] is a [[recessive]] [[Mutants|mutant]], which is reported in the wild from time to time in [[Assam]], Bengal, [[Bihar]] and especially in the former [[Rewa (princely state)|State of Rewa]]. However, it is not an occurrence of [[albinism]]. In fact, there is only one fully authenticated case of a true albino tiger, and none of black tigers, with the possible exception of one dead specimen examined in [[Chittagong]] in 1846.<ref name=McDougal1977>{{Cite book |last=McDougal |first=C. |year=1977 |title=The Face of the Tiger |publisher=Rivington Books and André Deutsch |location=London}}</ref> Fourteen Bengal tiger skins in the collection of the [[Natural History Museum, London]] have 21–29 stripes.<ref name=Kitchener1999/>

Three tigresses from the Bangladesh Sundarbans had a mean weight of {{Cvt|76.7|kg}}. The oldest female weighed {{Cvt|75|kg}} and was in a relatively poor condition at the time of capture. Their skulls and body weights were distinct from those of tigers in other habitats, indicating that they may have adapted to the unique conditions of the mangrove habitat. Their small sizes are probably due to a combination of intense intraspecific competition and small size of prey available to tigers in the Sundarbans, compared to the larger deer and other prey available to tigers in other parts.<ref name=Sundarbans>{{Cite thesis |last1=Barlow |first1=A.

The Bengal tiger's historical range covered the [[Indus River]] valley until the early 19th century, almost all of [[India]], western [[Pakistan]], southern [[Nepal]], [[Bangladesh]], [[Bhutan]], and southwestern [[China]]. Today, it inhabits India, Bangladesh, Nepal, Bhutan, and southwestern China.<ref name=Luo2004/>
It is estimated to have been present in the [[Indian subcontinent]] since the [[Late Pleistocene]], for about 12,000 to 16,500 years.<ref>{{Cite journal |last1=Kitchener |first1=A.

In the Indian subcontinent, Bengal tigers inhabit [[tropics|tropical]] moist [[evergreen forests]], [[tropical dry forest]]s, tropical and subtropical moist [[deciduous forest]]s, [[mangroves]], subtropical and temperate upland forests, and [[alluvial]] grasslands. The latter habitat once covered a huge swath of grassland, riverine and moist semi-deciduous forests along the major river system of the [[Gangetic plain|Gangetic]] and [[Brahmaputra River|Brahmaputra plains]], but has now been largely converted to agricultural land or severely [[Environmental degradation|degraded]]. Today, the best examples of this habitat type are limited to a few blocks at the base of the outer foothills of the [[Himalayas]] including the ''Tiger Conservation Units'' (TCUs) [[Rajaji National Park|Rajaji]]-[[Corbett National Park|Corbett]], [[Bardia National Park|Bardia]]-[[Banke National Park|Banke]], and the transboundary TCUs [[Chitwan National Park|Chitwan]]-[[Parsa National Park|Parsa]]-[[Valmiki National Park|Valmiki]], [[Dudhwa Tiger Reserve|Dudhwa]]-[[Kailali District|Kailali]] and [[Shuklaphanta National Park|Shuklaphanta]]-[[Kishanpur Wildlife Sanctuary|Kishanpur]].

During a tiger census in 2008, camera trap and sign surveys using [[GIS]] were employed to estimate site-specific densities of tiger, co-predators and prey. Based on the result of these surveys, the total tiger population was 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.

By 2009, the tiger population in the Bangladesh Sundarbans was estimated as 100–150 adult females or 335–500 tigers overall. Female home ranges, recorded using [[Global Positioning System]] collars, were some of the smallest recorded for tigers, indicating that the Bangladesh Sundarbans could have one of the highest densities and largest populations of tigers anywhere in the world. They are isolated from the next tiger population by a distance of up to {{Cvt|300|km}}. Information is lacking on many aspects of Sundarbans tiger ecology, including relative abundance, population status, spatial dynamics, habitat selection, life history characteristics, taxonomy, genetics, and disease. There is also no monitoring program in place to track changes in the tiger population over time, and therefore no way of measuring the response of the population to conservation activities or threats. Most studies have focused on the tiger-human conflict in the area, but two studies in the Sundarbans East Wildlife sanctuary documented habitat-use patterns of tigers, and abundances of tiger prey, and another study investigated tiger parasite load. Some major threats to tigers have been identified. The tigers living in the Sundarbans are threatened by [[habitat destruction]], prey depletion, highly aggressive and rampant [[intraspecific competition]], tiger-human conflict, and direct tiger loss.<ref name=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 National Park]] encompassing an area of {{Cvt|2543|km2}} of prime lowland forest. To the west, the Chitwan population is isolated from the one in [[Bardiya National Park]] and adjacent unprotected habitat farther west, extending to within {{Cvt|15|km}} of the Shuklaphanta Wildlife Reserve, which harbours the smallest population.<ref>{{Cite journal |author1=Smith, J.

===China===
The presence of the Bengal tiger in southeastern [[Tibet Autonomous Region]], China was investigated in 1995 when the loss of livestock was high in [[Mêdog County]] due to a large predator.

==Ecology and behaviour==
[[File:T 17 (Panthera tigris) - Koshyk.jpg|thumb|A tigress having a bath in Ranthambore Tiger Reserve, [[Rajasthan]]]]
The basic social unit of the tiger is composed of a female and her offspring. Adult animals congregate only temporarily when special conditions permit, such as plentiful supplies of food. Otherwise, they lead solitary lives, hunting individually for the forest and grassland animals upon which they prey. Resident adults of either sex maintain home ranges, confining their movements to definite habitats within which they satisfy their needs and those of their cubs, which include prey, water and shelter. In this site, they also 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.<ref name="McDougal1977"/> In [[Chitwan National Park]], [[Radio telemetry|radio-collared]] subadult tigers started [[Dispersal (ecology)|dispersing]] from their natal areas earliest at the age of 19 months. Of the 14 subadults studied, the four females stayed closer to their mother's home range than the 10 males. The latter dispersed between {{Cvt|9.5|and|65.7|km}}. None of them crossed open cultivated areas that were more than {{Cvt|10|km}} wide, but moved through prime alluvial and forested habitat.<ref>{{Cite journal |last=Smith |first=J. L. D. |year=1993 |title=The role of dispersal in structuring the Chitwan tiger population |volume=124 |journal=Behaviour |issue=3 |pages=165–195 |doi=10.1163/156853993X00560}}</ref>

In the Panna Tiger Reserve, an adult radio-collared male tiger moved {{Cvt|1.7|to|10.5|km}} between locations on successive days in winter, and {{Cvt|1|to|13.9|km}} in summer. His home range was about {{Cvt|200|km2}} in summer and {{Cvt|110|km2}} in winter. Included in his home range were the much smaller home ranges of two females, a tigress with cubs and a subadult tigress. They occupied home ranges of {{Cvt|16|to|31|km2}}.<ref>{{Cite book |author1=Chundawat, T. S. |author2=Gogate, N. |author3=Johnsingh, A. J.

[[File:Flying Princess (cropped).jpg|thumb|Female cubs playing in Ranthambore Tiger Reserve]]
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.<ref name="McDougal1977"/>

During seven years of camera trapping, tracking, and observational data in Chitwan National Park, six to nine breeding tigers, two to sixteen non-breeding tigers, and six to twenty young tigers of less than one year of age were detected in the study area of {{Cvt|100|km2}}. One of the resident females left her territory to one of her female offspring and took over an adjoining area by displacing another female; and a displaced female managed to re-establish herself in a neighbouring territory made vacant by the death of the resident. Of 11 resident females, 7 were still alive at the end of the study period, two disappeared after losing their territories to rivals, and two died. The initial loss of two resident males and subsequent take over of their home ranges by new males caused social instability for two years. Of four resident males, one was still alive and three were displaced by rivals. Five litters of cubs were killed by infanticide, two litters died because they were too young to fend for themselves when their mothers died. One juvenile tiger was presumed dead after being photographed with severe injuries from a deer [[snare trap|snare]]. The remaining young lived long enough to reach dispersal age, two of them becoming residents in the study area.<ref>{{Cite journal |last1=Barlow |first1=A. C.

===Hunting and diet===
[[File:RANTHAMBORE TIGER RESERVE.jpg|thumb|A tiger attacking a [[Sambar deer]] in Ranthambore Tiger Reserve]]
The Bengal tiger is a [[carnivore]] and prefers hunting large [[ungulate]]s such as [[gaur]], [[Sambar (deer)|sambar]], [[chital]], [[barasingha]], [[water buffalo]], [[nilgai]], [[serow]] and [[takin]]. Medium-sized prey includes [[wild boar]], [[Indian hog deer]], [[Indian muntjac]] and [[northern plains gray langur]]. Small prey such as [[Indian crested porcupine|porcupine]], [[hare]] and [[peafowl]] form a small part of its diet.

In most cases, Bengal 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 metres, 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 {{Cvt|18|-|40|kg}} of meat at one time.<ref name=Mazak1981 /> In one study, tigresses from [[Nepal]] made about 40–50 kills a year and ate a minimum of {{Cvt|5|-|6.3|kg}} of meat a day.

===Reproduction and lifecycle===

Males reach maturity at 4–5 years of age, and females at 3–4 years. A Bengal comes into [[estrus]] (commonly known as "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 {{Cvt|780|to|1600|g|lb}} and they have a thick woolly 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 to 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 home range. Young males move farther away from their native home range than young females. Once the family group has split, the mother comes into heat again.<ref name=Mazak1981 />

==Threats==
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.<ref name=iucn>{{cite iucn |author=Goodrich, J. |author2=Wibisono, H. |author3=Miquelle, D. |author4=Lynam, A.J. |author5=Sanderson, E. |author6=Chapman, S. |author7=Gray, T.N.E. |author8=Chanchani, P. |author9=Harihar, A. |year=2022 |title=''Panthera tigris'' |page=e.T15955A214862019 |doi=10.2305/IUCN.UK.2022-1.RLTS.T15955A214862019.en}}</ref>

The [[Forest Rights Act]] passed by the Indian government in 2006 grants some of India's most impoverished communities the right to own and live in the forests, which likely brings them into conflict with wildlife and under-resourced, under-trained, ill-equipped forest department staff. In the past, evidence showed that humans and tigers cannot co-exist.<ref>{{Cite news |last=Buncombe |first=A. |date=31 October 2007 |title=The face of a doomed species |url=https://www.independent.co.uk/environment/nature/the-face-of-a-doomed-species-398373.html |newspaper=The Independent}}</ref>

===Poaching===
The most significant immediate threat to the existence of wild tiger populations is the [[Wildlife trade#Illegal wildlife trade|illegal wildlife 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 (leather)|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 [[urbanisation]] 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.<ref name=eia2006>{{Cite report |author=Banks, D. |name-list-style=amp |author2=Lawson, S. |author3=Wright, B. |year=2006 |title=Skinning the Cat: Crime and Politics of the Big Cat Skin Trade |location=London |publisher=Environmental Investigation Agency, Wildlife Protection Society of India |url=http://www.wpsi-india.org/images/EIA-WPSI_Skinning_The_Cat.pdf}}</ref> In Bangladesh, tigers are killed by professional poachers, local hunters, trappers and villagers.

The illicit demand for bones and body parts from wild tigers for use in [[Traditional Chinese medicine#Animal substances|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.<ref>{{Cite book |author1=Hemley, G. |author2=Mills, J.

===Human–tiger conflict===
{{Main|Tiger attack}}
The Indian subcontinent has served as a stage for intense confrontations between tigers and people. At the beginning of the 19th century tigers were so numerous, that the killing of tigers was officially rewarded in many localities. The Terai region supported large numbers of tigers that were pushed into marginal habitat after the 1950s, when the conversion of natural habitat for paddy fields increased. Marauding tigers began to take a toll of human life in areas bordering cultivation. They are thought to have followed 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.<ref name=mcdougal1987>{{Cite book |last=McDougal |first=C. |date=1987 |chapter=The man-eating tigers in geographical historical perspective |editor-last1=Tilson |editor-first=R.

In the Sundarbans, 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. In areas where opportunistic man-eaters were found, the killing of humans was correlated with their availability, most victims being claimed during the [[honey]]-gathering season.<ref>{{Cite journal|author=Hendrichs, H. |year=1975|title=The status of the tiger (''Panthera tigris'') in the Sundarbans Mangrove|journal= Säugetierkundliche Mitteilungen |volume=23 |pages=161–199}}</ref> Tigers in the Sunderbans presumably attacked humans who entered their territories in search of wood, honey or fish, thus causing them to defend their territories. The number of tiger attacks on humans may be higher outside suitable areas for tigers, where numerous people are present, but with little wild prey for tigers.<ref>{{Cite journal |author=Jackson, P. |year=1985|title=Man-eaters |journal=International Wildlife |volume=15 |pages=4–11}}</ref>

In Nepal, the incidence of man-eating tigers has been only sporadic. In Chitwan National Park no cases were recorded before 1980. In the following few years, 13 people have been killed and eaten in the park and its environs. In the majority of cases, man-eating appeared to have been related to an intra-specific competition among male tigers.<ref name=mcdougal1987 />
An interview survey with 499 local people in Chitwan revealed that lower caste Hindus and people with less than eight years of formal education had negative attitudes to the tiger; most of them owned livestock and had heard about tigers attacking people and livestock.<ref>{{Cite journal |author1=Carter, N.H. |author2=Riley, S.J. |author3=Shortridge, A. |author4=Shrestha, B.K. |author5=Liu, J. |date=2014 |title=Spatial assessment of attitudes toward Tigers in Nepal |journal=Ambio |volume=43 |issue=2 |pages=125–137 |doi=10.1007/s13280-013-0421-7 |pmc=3906475 |pmid=23836312|bibcode=2014Ambio..43..125C }}</ref>

In December 2012, a tiger was shot by the [[Kerala Forest Department]] on a [[coffee plantation]] on the fringes of the [[Wayanad Wildlife Sanctuary]]. Chief Wildlife Warden of Kerala ordered the hunt for the animal after mass protests erupted as the tiger had been carrying away livestock. The Forest Department had constituted a special task force to capture the animal with the assistance of a 10-member Special Tiger Protection Force and two trained [[Indian elephant]]s from the [[Bandipur Tiger Reserve]] in [[Karnataka]].<ref>{{Cite news |title=Straying tiger meets with a bloody end |url=http://www.thehindu.com/news/national/kerala/straying-tiger-meets-with-a-bloody-end/article4159420.ece |newspaper=The Hindu |date=3 December 2012}}</ref><ref>{{Cite news |last=Manoj |first=E.

==Conservation efforts==
{{Main|Tiger conservation}}
An area of special interest lies in the "Terai Arc Landscape" in the [[Himalaya]]n foothills of northern India and southern Nepal, where 11 [[protected area]]s composed of dry forest foothills and tall-grass savannas harbour tigers in a {{Convert|49,000|km2|mi2}} 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.<ref name="future">{{cite book |last1=Damania |first1=R. |last2=Seidensticker |first2=J. |last3=Whitten |first3=T. |last4=Sethi |first4=G. |last5=Mackinnon |first5=K. |last6=Kiss |first6=A. |last7=Kushlin |first7=A. |year=2008 |url=http://si-pddr.si.edu/dspace/bitstream/10088/7930/1/986D8887-2F38-44FE-96A2-A59C8FAE96BE.pdf |title=A Future for Wild Tigers |publisher=The [[World Bank]] |location=[[Washington, D.C.]] |isbn=978-0-8213-6792-6 |access-date=24 September 2010 |archive-date=15 May 2013 |archive-url=https://web.archive.org/web/20130515021654/http://si-pddr.si.edu/dspace/bitstream/10088/7930/1/986D8887-2F38-44FE-96A2-A59C8FAE96BE.pdf |url-status=dead }}</ref>

===In India===
{{Main|Project Tiger}}
[[File:India Tiger cubs.jpg|thumb|A [[tigress]] with her cubs in [[Bandhavgarh National Park]], Madhya Pradesh]]

In 1973, [[Project Tiger]] was launched aiming at ensuring a viable tiger population 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 in India|tiger reserves]] as breeding nuclei, from which surplus animals would disperse to adjacent forests. The selection of areas for the reserves represented as close as possible the diversity of [[ecosystem]]s 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 {{Convert|9115|km2|sqmi}} had been increased to 15 reserves covering an area of {{Convert|24700|km2|sqmi}}. More than 1100 tigers were estimated to inhabit the reserves by 1984.<ref>Panwar, H. S. (1987).

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.<ref>Ramesh, R.

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 trap]]s 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.<ref>{{Cite news |title=Just 1,411 tigers in India |author=Sethi, N. |url=https://timesofindia.indiatimes.com/home/environment/flora-fauna/Just-1411-tigers-in-India/articleshow/2777803.cms |archive-url=https://web.archive.org/web/20110811044737/http://articles.timesofindia.indiatimes.com/2008-02-13/flora-fauna/27773614_1_tiger-population-sariska-tiger-numbers |url-status=live |archive-date=11 August 2011 |year=2008 |work=[[The Times of India]] | access-date=3 March 2009}}</ref>

===In Bangladesh===
WildTeam is working with local communities and the Bangladesh Forest Department to reduce human-tiger conflict in the Bangladesh Sundarbans. For over 100 years people, tigers, and livestock have been injured and killed in the conflict; in recent decades up to 50 people, 80 livestock, and 3 tigers have been killed in a year. Now, through WildTeam's work, there is a boat-based Tiger Response team that provides first aid, transport, and body retrieval support for people being killed in the forest by tigers. WildTeam has also set up 49 volunteer Village Response Teams that are trained to save tigers that have strayed into the village areas and would be otherwise killed. These village teams are made up of over 350 volunteers, who are also now supporting anti-poaching work and conservation education/awareness activities. WildTeam also works to empower local communities to access the government funds for compensating the loss/injury of livestock and people from the conflict. To monitor the conflict and assess the effectiveness of actions, WildTeam have also set up a human-tiger conflict data collection and reporting system.

==="Re-wilding" project in South Africa===
In 2000, the Bengal tiger re-wilding project ''Tiger Canyons'' was started by [[John Varty]], who together with the zoologist [[Dave Salmoni]] trained captive-bred tiger cubs how to stalk, hunt, associate hunting with food and regain their predatory instincts. They claimed that once the tigers proved that they can sustain themselves in the wild, they would be released into a free-range sanctuary of [[South Africa]] to fend for themselves.<ref>{{Cite web |year=2001 |title=Meet the Tiger Men: John Varty |url=http://dsc.discovery.com/convergence/tigers/trainers/trainers_02.html |website=Discovery Channel |url-status=dead |archive-url=https://web.archive.org/web/20080603034011/http://dsc.discovery.com/convergence/tigers/trainers/trainers_02.html |archive-date=3 June 2008}}</ref>

The project has received controversy after accusations by their investors and conservationists of manipulating the behaviour of the tigers for the purpose of a film production, ''[[Living with Tigers]]'', with the tigers believed to be unable to hunt.<ref name=envirolink>{{Cite web |title=Tiger Film a Fraud, says The Chinese Tigers South African Trust |url=http://lists.envirolink.org/pipermail/ar-news/Week-of-Mon-20030901/005990.html |date=2003 |agency=PR Newswire |url-status=dead |archive-url=https://web.archive.org/web/20110727084010/http://lists.envirolink.org/pipermail/ar-news/Week-of-Mon-20030901/005990.html |archive-date=27 July 2011}}</ref><ref name=wildeye>{{Cite web|title=Discovery Film Proclaimed A Fraud; Broadcaster to be Sued |url=http://www.wildeye.co.uk/wildlife-film/Wfn/wfn56.htm |website=Wildlife Film News 56 |date=February 2004 |access-date=27 August 2011 |url-status=dead |archive-url=https://web.archive.org/web/20090607012741/http://www.wildeye.co.uk/wildlife-film/Wfn/wfn56.htm |archive-date=7 June 2009}}</ref> Stuart Bray, who had originally invested a large sum of money in the project, claimed that he and his wife, Li Quan, watched the film crew "[chase] the prey up against the fence and into the path of the tigers just for the sake of dramatic footage."<ref name=envirolink/><ref name=wildeye/>

The four tigers involved in this project have been confirmed to be crossbred Siberian–Bengal tigers, which should neither be used for breeding nor being released into the [[Karoo]].
