Tiger reserves

1. Meaning, purpose and evolution

A tiger reserve is a conservation landscape designated under the Wild Life (Protection) Act, 1972, specifically to sustain viable populations of wild tigers. Tigers require adequate prey, water, cover and space; their protection therefore benefits forests, grasslands, wetlands and many associated species. This makes the tiger an umbrella species as well as a flagship species. Tiger reserves also safeguard watersheds, store carbon and support regulated nature-based livelihoods.

Project Tiger was launched on 1 April 1973, initially covering nine reserves, including Corbett, Kanha, Manas, Melghat, Palamau, Ranthambore, Similipal, Bandipur and Sundarbans. It responded to falling tiger numbers caused by hunting, habitat loss and prey depletion. The disappearance of tigers from Sariska, publicly established in 2005, exposed weaknesses in protection and monitoring and accelerated institutional reform.

Tiger reserve is not a synonym for national park. A reserve may include one or more national parks or wildlife sanctuaries and adjoining forests or other land in its buffer. Likewise, a tiger reserve is not a conservation reserve: the latter is a separate legal designation under Section 36A. Biosphere reserves follow a different conservation framework and are not, by that designation alone, a protected-area category under the Act.

• The tiger, Panthera tigris, is listed in Schedule I of the Wild Life (Protection) Act and classified as Endangered on the IUCN Red List.
• India's tiger landscapes include the Shivalik–Gangetic plains, Central India and Eastern Ghats, Western Ghats, northeastern hills and Brahmaputra plains, and Sundarbans.

2. Legal framework and institutions

The 2006 amendment inserted dedicated tiger-conservation provisions into the Wild Life (Protection) Act. Section 38L provides for the National Tiger Conservation Authority, or NTCA, a statutory body under the Ministry of Environment, Forest and Climate Change. Chaired by the Union Environment Minister, it approves Tiger Conservation Plans, sets standards, evaluates management and supports protection and monitoring. Project Tiger is the programme; NTCA is the statutory authority.

Under Section 38V, the state government notifies a tiger reserve on NTCA's recommendation and prepares a Tiger Conservation Plan. The plan must address protection, habitat management, adequate prey, ecologically compatible land use and the livelihood interests of local people. Management must also consider dispersal habitats and connections with other protected areas, rather than treating each reserve as an isolated forest island.

The law places strong safeguards on reducing protection. A tiger reserve's boundaries cannot be altered except on NTCA's recommendation and the approval of the National Board for Wild Life. De-notification requires public interest and approval of both bodies. State forest departments undertake field management, while the Wildlife Crime Control Bureau supports action against organised wildlife crime. Tiger Conservation Foundations provide an institutional mechanism for supporting conservation and associated local development.

• NTCA does not replace the state forest department as the routine field-management agency.
• A Tiger Conservation Plan is a statutory planning requirement, not merely a tourism plan.

3. Core, buffer and community rights

The core or critical tiger habitat comprises areas of national parks and sanctuaries scientifically identified as necessary to be kept inviolate for tiger conservation. Its determination must follow the statutory expert-consultation process and must not casually override the rights of Scheduled Tribes and other forest dwellers. Inviolate habitat is intended to minimise incompatible human disturbance in essential breeding and survival areas.

The buffer or peripheral area surrounds or adjoins the core and requires a lower degree of habitat protection. Its purpose is to support dispersal, reduce pressures on the core and promote coexistence between wildlife and human activity, with due recognition of local livelihood, developmental, social and cultural rights. Buffer boundaries are determined using scientific and objective criteria in consultation with the concerned Gram Sabhas and an expert committee.

Notification does not automatically extinguish rights or authorise eviction. Where relocation is proposed to establish inviolate areas, statutory safeguards include recognition and determination of rights, examination of coexistence possibilities, an adequate rehabilitation package, informed consent of the Gram Sabha and affected persons, and provision of facilities and land allocation at the rehabilitation site before displacement. The Forest Rights Act, 2006 is therefore central to lawful implementation.

Critical tiger habitat under the wildlife law must be distinguished from critical wildlife habitat under the Forest Rights Act. Their legal bases and identification procedures differ. Tourism is also not an unrestricted entitlement: it must conform to applicable guidelines, zoning, carrying capacity and the Tiger Conservation Plan. Neither a blanket claim that tourism is permitted everywhere nor that all tourism is prohibited throughout every core is correct.

4. Monitoring, corridors and conservation challenges

India's All India Tiger Estimation combines field evidence, camera trapping and statistical analysis. Individual tigers can be recognised from their unique stripe patterns. The 2022 assessment produced an estimated population of 3,682, with a range of 3,167–3,925. The earlier headline figure of 3,167 should not be confused with the subsequently released estimate of 3,682. National estimates include tigers outside notified reserves.

M-STrIPES, or Monitoring System for Tigers–Intensive Protection and Ecological Status, supports patrol recording and ecological monitoring. Camera traps, spatial analysis and field intelligence complement rather than replace trained personnel. Management Effectiveness Evaluation assesses how well reserves are managed, while population monitoring assesses tiger occurrence and abundance; the two exercises answer different questions.

Major threats include poaching, illegal trade in body parts, prey depletion, forest fragmentation, linear infrastructure, invasive plants and human–tiger conflict. Corridors permit dispersal and gene flow between populations, reducing isolation. Roads, railways, mines and poorly planned settlements can sever these connections. Mitigation requires landscape-level assessment, avoidance of critical habitats, appropriate wildlife crossings and monitoring of their actual use.

Conflict prevention combines secure livestock husbandry, prompt compensation, early warning and trained response teams. Reserve success should be judged by breeding populations, prey availability, habitat quality, connectivity and community outcomes, not tiger numbers alone.

5. Geography and Prelims distinctions

Map-based preparation should connect reserves with states, river systems and habitat types. Sundarbans in West Bengal protects tidal mangroves; Kaziranga in Assam includes floodplain grasslands; Periyar in Kerala lies in the southern Western Ghats; and Namdapha in Arunachal Pradesh spans a large altitudinal gradient. Nagarjunsagar–Srisailam in Andhra Pradesh is associated with the Nallamala hills and Krishna basin.

Among the original reserves, Corbett lies in Uttarakhand, Kanha and Bandipur in Madhya Pradesh and Karnataka respectively, and Melghat in Maharashtra's Satpura landscape. Learn these stable geographical associations before memorising changing totals. A reserve's notification does not mean that every part has identical legal restrictions, that all tiger habitat lies within reserves, or that corridors automatically acquire a separate protected-area status.
