  • Conversion: Sanctuaries can be upgraded to national parks, but reverse conversion is not permitted

Wildlife sanctuaries form the backbone of India's biodiversity conservation strategy under the Wildlife Protection Act, 1972. They:

  • Provide safe breeding grounds for endangered species like Great Indian Bustard, Snow Leopard, and One-horned Rhinoceros
  • Act as corridors connecting fragmented habitats for wildlife movement
  • Support over 47,000 species of flora and 1,00,000+ species of fauna found in India
  • Contribute to India's status as one of 17 megadiverse countries globally
