Project Tiger was launched in 1973 in India to ensure viable wild tiger populations by preserving their natural habitats. It created tiger reserves with core protected areas surrounded by buffer zones where limited human activities are allowed. While India once had 20,000-40,000 tigers, a 1995 census found only around 1,800 remaining, due to poaching and habitat loss. Project Tiger aims to eliminate human exploitation from core areas and reasonably manage buffer zones to help tiger populations recover.
