States with most tigers: Madhya Pradesh (785), Karnataka (563), Uttarakhand (560), Maharashtra (444), Tamil Nadu (306).

India has 18 Biosphere Reserves; 12 included in UNESCO World Network. Tiger Reserve: Designated under Project Tiger; has Core (Critical Tiger Habitat) and Buffer zone. India has 53 Tiger Reserves (as of 2024). Ramsar Site: Wetland of international importance — designated under Ramsar Convention (1971). India has 80 Ramsar sites (2024) — largest number in world.
