Only 1,000 tigers remain in India, down drastically from 40,000 a century ago, due to extensive hunting and poaching. Two Indian tiger reserves, Panna and Sariska, have lost their tiger populations. Poaching to supply demand for tiger parts in Chinese medicine is a major threat, along with habitat loss from electric fences, logging, and conflicts between male tigers over territory. Several tiger subspecies are critically endangered or extinct, including the Bali tiger, while the Sumatran tiger faces threats from poaching and habitat destruction. Protecting remaining tiger habitats and combating poaching of tigers for traditional medicine are critical to the species' survival.
