Project Tiger 1973: Reserves, Population, NTCA, Core-Buffer Strategy

Project Tiger is the longest-running and most studied wildlife conservation programme in India. Launched on 1 April 1973 from Jim Corbett National Park, it has shaped how the country thinks about protected areas, statutory authorities, and the politics of coexistence between people and predators. Today, it covers 58 tiger reserves and an estimated tiger population of 3,682, which means India hosts roughly three out of every four wild tigers on Earth.

That headline number is the easy part. The harder part is what the programme actually does. Project Tiger pioneered the core-buffer model that became the template for tiger reserves in Asia. It pulled tiger conservation out of state forest departments and gave it a national authority with statutory powers. It also exposed the deep tensions between strict protection, tribal rights, and tourism that every conservation question in India eventually circles back to.

This guide walks through the programme as it actually exists in 2026, the institutional architecture under the Wildlife (Protection) Act, the science behind the four-yearly All India Tiger Estimation, and the policy debates that keep showing up in mains papers.

What Project Tiger Is and Why It Was Created

Project Tiger is best understood as a conservation programme that became a statutory regime. When it began in 1973, India had only nine tiger reserves and an estimated 1,827 tigers, down from a population that may once have crossed 40,000. The trigger was a 1969 IUCN warning that the Bengal tiger was sliding toward extinction in its largest range state. The Indian Board for Wildlife endorsed the project, the Wildlife (Protection) Act of 1972 created the legal scaffolding, and the programme was formally launched the next year.

The original idea was practical. Pick representative tiger landscapes across India, give them strict legal protection, manage their core areas as inviolate spaces, and surround those cores with buffer zones where regulated human use could continue. That blueprint was new for India and became influential across the tiger range.

What changed in 2006 was the institutional layer. Following the Sariska crisis, where tigers vanished from the reserve due to poaching and management failure, Parliament amended the Wildlife (Protection) Act to create the National Tiger Conservation Authority. NTCA gave Project Tiger statutory teeth, a permanent secretariat, and binding power to issue directions to states.

Background and Historical Context

The colonial period treated the tiger as a trophy and a threat. Hunting records from princely states and viceregal shoots routinely list double-digit kills in a single tour. Bounties on tigers continued into the 1950s. By independence, range maps showed serious contraction in central India, the terai, and the Western Ghats.

The 1969 IUCN General Assembly in New Delhi formally placed the tiger on the endangered list, which jolted the Indian Board for Wildlife into action. Indira Gandhi’s government created a Task Force in 1970, and its 1972 report became the design document for Project Tiger. The first nine reserves were Corbett, Manas, Ranthambore, Palamau, Bandipur, Similipal, Sundarbans, Kanha, and Melghat. They covered roughly 14,000 square kilometres and represented the major tiger habitat types in India.

The next two decades produced uneven results. Estimation methodology relied heavily on pugmark tracing, which generated inflated numbers and masked local extinctions. The 2005 Sariska shock, where the WII confirmed that the reserve had lost all its tigers, forced a methodological reset. The 2006 amendment, the Tiger Task Force report, and the rollout of the camera-trap based All India Tiger Estimation in 2006 together rebuilt the programme on more rigorous foundations.

Key Provisions and Institutional Architecture

The legal home of Project Tiger today is Chapter IV-B of the Wildlife (Protection) Act, 1972, which lays down the powers of the NTCA, the procedure for declaring a tiger reserve, the concept of Critical Tiger Habitat, and the rehabilitation provisions for villages inside cores.

The National Tiger Conservation Authority is chaired by the Union Minister for Environment, Forest and Climate Change. It approves Tiger Conservation Plans submitted by states, lays down standards and guidelines for tiger conservation, evaluates management effectiveness, and disburses central funds. It also maintains the official tiger database and publishes the Status of Tigers report every four years.

Each reserve has a two-zone structure. The Critical Tiger Habitat, also called the core, is notified after a scientific assessment and is meant to be kept inviolate from human settlement. The buffer surrounds the core and is managed for coexistence, regulated tourism, and sustainable livelihoods. Voluntary, fully compensated relocation from the core is the standard policy, and rehabilitation packages are revised periodically.

Tiger Conservation Foundations, set up at the reserve level, bring together state forest officers, panchayat representatives, and community members for day-to-day governance. The Tiger Strike Force in many states focuses on anti-poaching operations.

Why Project Tiger Matters

The programme is the rare conservation intervention that delivered measurable population recovery while building institutions that outlasted political cycles. The tiger functions as an umbrella species, which means protecting its landscapes also protects co-predators like leopard and dhole, large prey like sambar and gaur, and the broader forest community including pollinators, soil microbes, and watershed services.

For UPSC mains, Project Tiger is also a case study in cooperative federalism. Wildlife is in the Concurrent List, and tiger reserves sit within state forest territories, but a central authority sets standards, releases funds, and has the power to direct states under the Wildlife (Protection) Act. The programme also intersects with Forest Rights Act jurisprudence, the eco-sensitive zone notification regime, and the EIA process for projects in tiger landscapes.

Detailed Analysis: The Core-Buffer Strategy

The core-buffer model is the operational heart of Project Tiger. Its logic is biological rather than administrative. Tigers need large, undisturbed prey-rich areas to breed and rear cubs. They also need connectivity to neighbouring populations so that genetic diversity does not collapse and dispersing sub-adults find new territories.

The Critical Tiger Habitat is the breeding zone. Notification follows a scientific committee process and requires recognition of forest rights under the FRA before any rights are modified. Once notified, the CTH is closed to mining, dams, commercial forestry, and new settlement. Existing rights-holders can opt for voluntary relocation, and as per latest available data the standard package is around fifteen lakh rupees per family along with land or housing alternatives.

The buffer is where the politics happens. It accommodates village commons, regulated tourism, eco-development, and corridor management. Buffer notifications are negotiated with panchayats and frequently litigated, because they trigger restrictions on land use without conferring relocation benefits. The buffer’s success depends on Tiger Conservation Foundations, eco-development committees, and partnerships with district administrations.

Around the formal reserve, the eco-sensitive zone notified under the Environment (Protection) Act extends a graded buffer of restrictions on red and orange category industries. Beyond that, NTCA-designated tiger corridors connect reserves across landscapes such as the Central Indian, Western Ghats, Sivalik-Terai, North-Eastern Hills, and Sundarbans clusters.

Tiger Census Methodology and Population Trends

The All India Tiger Estimation, conducted every four years by NTCA in partnership with the Wildlife Institute of India and state forest departments, has been the world’s largest wildlife survey since 2006. It combines double-sampling with sign surveys across the entire forested landscape, camera-trap based capture-recapture sampling in tiger-occupied areas, and statistical modelling to produce population estimates with confidence intervals.

The 2006 cycle estimated 1,411 tigers, 2010 estimated 1,706, 2014 estimated 2,226, 2018 estimated 2,967, and 2022 estimated 3,682. The trend is positive, but the gains are not uniform. Central India and the Western Ghats have driven most of the growth. Some reserves in the North-East, in eastern Maharashtra, and in parts of Odisha continue to face poaching pressure, prey depletion, and weak protection.

Challenges Facing Project Tiger

Despite the population recovery, structural challenges persist. Habitat fragmentation outside reserves keeps shrinking corridors, and linear infrastructure such as highways, railways, and canals continues to bisect tiger movement routes. Several reserves report saturation, where the carrying capacity is reached and dispersing tigers spill into human-use landscapes, driving up conflict.

Poaching for skin, bone, and traditional Asian medicine remains a persistent threat, even though the trade has shifted online and now relies on encrypted communication. Protection capacity is uneven, with some reserves operating well below sanctioned strength and many forest guards working with outdated equipment.

The relocation of villages from cores has made progress but remains incomplete. Implementation has sometimes failed to follow the Forest Rights Act process, drawing litigation and tribal community resistance. Tourism pressure in flagship reserves has pushed core-zone safari capacity to the edge of what NTCA permits. Climate change is now adding a new layer, with shifting rainfall patterns affecting prey distribution and water availability in many reserves.

Mains Practice Questions

• (GS-III) Project Tiger is often cited as a successful conservation programme. Critically evaluate its achievements and the structural challenges that constrain further progress.
• (GS-III) Discuss the significance of the core-buffer strategy in tiger conservation. How has the National Tiger Conservation Authority operationalized this strategy?
• (GS-II) Examine the role of cooperative federalism in the implementation of Project Tiger, with reference to the Wildlife (Protection) Act, 1972.
• (GS-III) The recovery of tiger numbers in India has not been uniform across landscapes. Identify the factors driving regional variation and suggest a policy framework to address them.

Way Forward

Project Tiger needs a corridor-first agenda for its next decade. Securing the 32 tiger corridors through smart green infrastructure such as overpasses, eco-bridges, and underpasses on national highways can reduce roadkill and maintain genetic flow. Empowering Tiger Conservation Foundations with predictable budgets and panchayat representation will strengthen the buffer governance that core protection ultimately depends on. Modernization of anti-poaching units with thermal cameras, drone surveillance, and trained sniffer-dog squads is overdue in the high-pressure reserves of Central India and the North-East. Convergence with the Forest Rights Act, transparent voluntary relocation processes, and credible livelihoods packages will reduce conflict around cores. Finally, integrating climate adaptation into Tiger Conservation Plans through water-source augmentation, prey base monitoring, and fire management will protect the gains of the past five decades.
