The Bengal tiger (Panthera tigris tigris) is a tiger population native to the Indian subcontinent. It is listed as Endangered on the IUCN Red List since 2008, and was estimated at comprising fewer than 2,500 individuals by 2011. It is threatened by poaching, loss, and fragmentation of habitat. None of the Tiger Conservation Landscapes within its range is considered large enough to support an effective population of more than 250 adult individuals. India's tiger population was estimated at 1,706–1,909 individuals in 2010. By 2014, the population had reputedly increased to an estimated 2,226 individuals. Around 440 tigers are estimated in Bangladesh, 163–253 tigers in Nepal and 103 tigers in Bhutan.
The tiger is estimated to be present in the Indian subcontinent since the Late Pleistocene, for about 12,000 to 16,500 years.
