The Indian Wildlife (Protection) Act was implemented in 1972, with various provisions for protecting habitats. An all-India list of protected species was also published. The thrust of the programme was towards protecting the remaining population of certain endangered species by bauring hunting, giving legal protection to their habitats, and restricting trade in wildlife.Subsequently cental and many state governments established national parks and wildlife sanctuaries. The central government also announced several projects for protecting specific animals, which were gravely threatened, including tiger, one-harved rhinceerous, the hangul and three types of crocodiles. Many other wild animals have been given full or partial legal protection against hunting and trade throughout India.
