What Happened

The National Tiger Conservation Authority (NTCA) has identified 25 of India's 58 tiger reserves as needing priority intervention due to critically low or absent tiger populations.
The identification follows an analysis of distribution data from the All India Tiger Estimation 2022 and ongoing reserve-level assessments, highlighting significant inter-reserve disparities in population recovery.
Reserves in states including Jharkhand, Odisha, Chhattisgarh, Telangana, and Andhra Pradesh are among those flagged, reflecting persistent issues of poaching, habitat degradation, and prey-base depletion in these landscapes.
Priority interventions being considered include tiger reintroduction (as piloted successfully at Sariska), anti-poaching intensification, prey augmentation, and improved wildlife corridor management.
The findings underscore that India's impressive national tiger count conceals a highly uneven geographic distribution, with a handful of well-managed reserves accounting for the bulk of the population.

Project Tiger (1973) — History and Objectives

Project Tiger was launched on 1 April 1973 by the Ministry of Environment, Forest and Climate Change, initially covering nine tiger reserves. It is the Government of India's flagship species-specific conservation programme. The core strategy is the "core-buffer" model: a strictly protected core zone (Critical Tiger Habitat) where no human habitation is permitted, surrounded by a buffer zone allowing limited human use and eco-development.

Launched in response to a precipitous decline in tiger numbers from an estimated 40,000 at the turn of the 20th century to fewer than 1,900 in the 1972 census.
Nine founding reserves (1973): Corbett, Kanha, Manas, Melghat, Palamau, Ranthambhore, Simlipal, Sundarbans, Bandipur.
Coverage has expanded to 58 reserves across 18 states, covering approximately 78,000 sq km.
India's tiger population grew from ~1,411 (2006) to 3,682 (2022), a nearly 2.6-fold increase in 16 years.

Connection to this news: Project Tiger's success has been geographically uneven; the NTCA's priority intervention list identifies reserves where the programme's management and protection mechanisms have not delivered population recovery.

National Tiger Conservation Authority (NTCA) — Establishment and Powers

The NTCA was established in December 2005 as a statutory body under the Wildlife Protection Act (WPA) 1972, through a 2006 amendment inserting Chapter IVB (Sections 38L–38Y). It superseded the Project Tiger Directorate and gave tiger conservation a statutory, rather than merely administrative, foundation. The NTCA is chaired by the Union Minister of Environment and includes wildlife experts and state chief wildlife wardens.

Section 38L: constitutes the NTCA.
Section 38O: empowers NTCA to evaluate and assess various aspects of tiger reserves and provide technical and other assistance to states.
Section 38V: mandates the preparation of a Tiger Conservation Plan for each reserve.
NTCA administers the annual tiger monitoring system (using camera traps, pugmark transects, and occupancy modelling) across all reserves.
NTCA approval is required before any project that alters or disturbs a tiger reserve's core or buffer zone.

Connection to this news: The NTCA's identification of 25 priority reserves flows directly from its statutory mandate under Section 38O to evaluate reserve performance and recommend interventions.

Tiger Reserve Structure — Core (Critical Tiger Habitat) and Buffer Zones

Under Section 38V of WPA 1972 (as amended in 2006), each tiger reserve must be delineated into a Core Area (Critical Tiger Habitat, CTH) and a Buffer Zone. The CTH is inviolate: no relocation except for project-affected communities with their consent, and no commercial exploitation of forest produce. The buffer zone allows co-existence of wildlife with local communities, subject to eco-development activities.

CTH declaration requires a scientific determination that it is "required to be kept as inviolate for the purpose of tiger conservation."
Human relocation from CTHs is voluntary and backed by rehabilitation packages.
Buffer zones serve as transition zones that reduce human-wildlife conflict at the reserve boundary.
Wildlife corridors connecting reserves fall partly within buffer zones and partly in revenue/forest lands outside reserve boundaries.

Connection to this news: Reserves with low tiger numbers often suffer from inadequate CTH protection, encroachment into buffer zones, and disrupted corridors that prevent natural tiger dispersal.

Sariska Tiger Reserve — India's First Tiger Reintroduction Case

Sariska Tiger Reserve (Rajasthan, in the Aravalli hills near Alwar) was notified as a Project Tiger reserve in 1978. By 2003–04, all tigers vanished from the reserve — confirmed in January 2005 — the result of systematic poaching by an organised gang. The loss was a landmark crisis in Indian wildlife conservation, exposing failures of anti-poaching infrastructure and field intelligence.

India's response was unprecedented: in July 2008, two tigers (one male, one female) were translocated from Ranthambhore National Park to Sariska — the world's first tiger reintroduction programme. A second female followed in February 2009.

By 2018: approximately 18 tigers in Sariska; by 2023: approximately 30 tigers — a full population recovery.
The Sariska success demonstrated that tiger reintroduction is viable in India when backed by intensive protection, prey augmentation, and habitat restoration.
The crisis also prompted the 2006 amendment to WPA 1972, giving statutory teeth to the NTCA.
Sariska is in the Shivalik-Aravalli landscape, different from the central Indian tiger landscape (Madhya Pradesh, Maharashtra, Chhattisgarh).

Connection to this news: Sariska is the proof-of-concept for reintroduction as a tool for priority intervention in depleted reserves — directly relevant to NTCA's strategy for the 25 identified reserves.

India's Tiger Population — Census Data and Global Significance

India conducts a national tiger census every four years using a rigorous protocol: Phase I (sign surveys across 6,41,449 sq km), Phase II (camera-trap grid across tiger reserves and forests), and Phase III (occupancy modelling). The All India Tiger Estimation 2022 estimated 3,682 tigers, up from 2,967 in 2018 and 2,226 in 2014 — an annual growth rate of approximately 6.1%.

India hosts approximately 75% of the world's wild tiger population.
Madhya Pradesh has the highest number of tigers (~785); Karnataka and Uttarakhand follow.
Bengal Tiger (Panthera tigris tigris) is listed as Endangered on the IUCN Red List and in CITES Appendix I (banning international commercial trade).
The global wild tiger population is estimated at approximately 5,500 (IUCN, 2022 data).
India has 58 tiger reserves spread across 18 states (as of 2024).

Connection to this news: Despite the impressive national total, 25 of 58 reserves have failed to sustain viable tiger populations — highlighting that aggregate success masks localised failure.

Wildlife Corridors and Landscape-Level Conservation

Tigers are wide-ranging apex predators requiring large, connected territories. A single male tiger may range over 100–150 sq km. Genetic viability of small, isolated reserve populations depends on dispersal corridors linking reserves. The Wildlife Institute of India has mapped approximately 32 critical tiger corridors across India, including the central Indian landscape (connecting Kanha–Pench–Tadoba–Melghat) and the Terai Arc Landscape (connecting Corbett–Dudhwa–Bardia in Nepal).

Corridors pass through revenue lands, community forests, and production forests — not within formal PAs — making them vulnerable to linear infrastructure, agriculture, and settlement.
National Board for Wildlife (NBWL) clearance is required for projects inside eco-sensitive zones of Protected Areas.
The NTCA's "Landscape-level conservation" approach emphasises meta-population management across multiple reserves, not just reserve-level protection.

Connection to this news: Reserves with absent or low tigers in the priority list are often isolated landscapes where corridor connectivity has broken down, cutting off natural recolonisation from source populations.
