Quick answer: Nahargarh Wildlife Sanctuary is a protected area in the Aravalli hills next to Jaipur, Rajasthan, notified in 1980. On 3 November 2026 the Supreme Court refused to rule on a challenge to its redrawn boundary and told the petitioner to argue the matter before the Rajasthan High Court, where the revised map is already being contested.
Why Nahargarh Wildlife Sanctuary is in the news
According to a report in India Legal, a Bench of Chief Justice of India Surya Kant and Justices Joymalya Bagchi and V. Mohana heard an appeal by environmental activist Rajendra Tiwari on Tuesday, 3 November 2026. The appeal (Civil Appeal No. 13859/2026, Rajendra Tiwari v. Union of India & Ors.) came out of National Green Tribunal (NGT) proceedings on how the sanctuary and the Nahargarh Reserve Forest should be demarcated. The key question was whether the revenue area of Nahargarh village falls inside the protected area.
Tiwari argued that the original notification had covered the village’s revenue land, and that the Forest Department later changed the map without the approval of the National Board for Wildlife (NBWL). The Bench did not go into these merits. It said the identity and limits of the sanctuary must first be settled by the High Court, which is already hearing a challenge to the revised map. It added that the High Court’s finding, once final, will bind every party, including government authorities.
Key facts about Nahargarh Wildlife Sanctuary
- Location: Aravalli hills near Jaipur, Rajasthan, roughly 20 km from the city.
- Notified: 1980; area usually given as about 50 sq km.
- Vegetation: semi-arid dry deciduous forest and thorny scrub, with trees such as dhok (Anogeissus pendula), babool, khejri and ber.
- Wildlife: leopard, sloth bear, hyena and jackal; over 285 bird species recorded.
- Nahargarh Biological Park lies inside the sanctuary and keeps tigers, Asiatic lions and other animals, with a rescue centre.
- Eco-Sensitive Zone: the Union environment ministry notified an ESZ around the sanctuary in 2019.
How the boundary dispute began
The trouble goes back to the 1980 notification, whose boundary description was rough. A mapping committee member told The Times of India in 2025 that it was “grossly approximate” and that decades of urban growth had changed the ground. The Forest Department then prepared a GIS-based map using satellite imagery and land records, and final administrative approval came on 18 July 2025.
| Point | Detail (as reported in 2025) |
|---|---|
| Revised extent filed before NGT | 6,025.74 hectares across 16 villages |
| Villages in the 1980 list | 13 (three more added in the revised map) |
| Legal objection | No NBWL approval, which Section 26A of the Wildlife (Protection) Act, 1972 requires |
| Precedent cited by critics | Supreme Court’s 2013 ruling in Centre for Environmental Law, WWF-India v. Union of India |
Critics say the new map drops privately and publicly owned revenue land and may shield hotels in and around the sanctuary; the department says it only corrects an imprecise 1980 description.
The legal rule on changing a sanctuary boundary
Once a sanctuary is notified under the Wildlife (Protection) Act, 1972, its limits cannot be redrawn at will. Section 26A ties any such change to a recommendation of the NBWL, and the Supreme Court’s 2013 WWF-India ruling reinforced that requirement. The Nahargarh case therefore turns on one question: was the 2025 map only a correction of a vague description, or did it actually alter the protected area? Rajasthan has redrawn a protected-area boundary only once before, at Sariska, according to the 2025 report.
Exam angle: how NDA, CDS and CAPF can ask this
- Protected areas of Rajasthan (Ranthambore, Sariska, Keoladeo, Desert National Park) are a regular area for location-based questions in NDA and CDS geography.
- The Aravalli range, one of the oldest fold mountain systems in India, is often asked in physical geography.
- CAPF and CDS can test the roles of the NGT and NBWL under the Wildlife (Protection) Act, 1972.
