How Protected Areas Are Classified

India's protected areas, under the Wildlife Protection Act, 1972, fall into four categories, in descending order of restriction:
| Category | Restriction Level | Notes |
|---|---|---|
| National Park | Strictest — no human activity, grazing, or private rights permitted without special permission | Declared by state government under Section 35; boundaries fixed by legislature, hardest to denotify |
| Wildlife Sanctuary | High, but some regulated human activity (grazing, resource collection, even limited habitation) may be permitted | Larger in number than National Parks; boundaries can be altered more easily by the state government |
| Conservation Reserve | Buffer/connector zones, usually adjoining existing PAs, on government land | Introduced by the Wildlife (Protection) Amendment Act, 2002 |
| Community Reserve | Buffer/connector zones on community or private land, managed with local participation | Also introduced by the 2002 amendment; the only category where private land rights are not extinguished |
A related but distinct layer worth not confusing with the above: Tiger Reserves (under Project Tiger, administered by the National Tiger Conservation Authority since the Wildlife Protection Act was amended in 2006) and Biosphere Reserves (a UNESCO Man and Biosphere Programme designation, not a Wildlife Protection Act category at all) are overlaid on top of NPs/WLS rather than being a separate rung of the same ladder. A single landscape — Kanha, Nanda Devi, Similipal, Sundarbans — can simultaneously be a National Park, a Tiger Reserve, and a Biosphere Reserve; these are three different laws/programmes recognising the same ground.
Memory hook: "National Parks No-touch, Wildlife Sanctuaries Some-touch." NP = strict; WLS = flexible; the newer Conservation/Community Reserves exist specifically to link fragmented habitats. And "Tiger Reserves Top-up, Biosphere Reserves Broad-brush" — both are extra labels laid over an existing NP/WLS, not replacements for it.
