On International Tiger Day (29 July), the Government reaffirmed India's position as home to nearly 70% of the world's wild tigers — a recovery rooted in five decades of structured policy, science-based monitoring and cooperative federalism.

Project Tiger now covers 58 reserves across 18 States — together about 2.56% of India's land area acts as structured sanctuary for the world's largest wild tiger population. Image courtesy PIB/MoEFCC; reproduced with credit for educational use.

India conducts the All India Tiger Estimation (AITE) every four years, jointly led by NTCA and the Wildlife Institute of India (WII), Dehradun. The 2022 AITE is recognised as the world's largest biodiversity survey, covering 20 States and over 6.41 lakh km surveyed on foot.

India's tiger population more than doubled in 16 years, growing at approximately 6% annually — a rare instance of large carnivore recovery at this scale. Image courtesy PIB/NTCA; reproduced with credit for educational use.

• 2006 AITE: 1,411 tigers — baseline estimate after independent camera-trap methodology was standardised.
• 2010 AITE: 1,706 tigers — first measurable recovery; coincided with strengthened NTCA oversight post-2006 amendments.
• 2014 AITE: 2,226 tigers — confirmed upward trend; Madhya Pradesh and Karnataka emerged as top-population States.
• 2018 AITE: 2,967 tigers — PM announced results on World Tiger Day 2019; India achieved Tx2 goal (doubling from 2010) four years ahead of the global 2022 target.
• 2022 AITE: 3,682 tigers — largest wild tiger population ever scientifically assessed in India.
• Global context: Of approximately 5,711 wild tigers estimated worldwide (latest global figure), India hosts about 64–70%. Global numbers grew roughly 78% since 2010 when the St. Petersburg Summit set the Tx2 goal.

• M-STrIPES (Monitoring System for Tigers – Intensive Protection and Ecological Status): GPS/GPRS-enabled mobile application for frontline forest staff. Field observations — patrol logs, evidence of poaching, wildlife sightings — are fed into a centralised database in real time. Reduces manual error and enables evidence-based patrol planning.
• CaTRAT (Camera Trap Data Repository and Analysis Tool): AI-powered image classification platform that automatically identifies species from camera trap images, dramatically reducing the manual processing bottleneck in large surveys.
• ExtractCompare: Individual tiger identification software that uses the unique stripe patterns of tigers (analogous to fingerprints) to count individual animals without double-counting. Critical for population estimate accuracy.
• Guinness Record: NTCA's camera trap survey holds the Guinness World Record for the world's largest camera trap wildlife survey.
• Management Effectiveness Evaluation (MEE): Periodic assessment framework covering planning, protection processes and conservation outcomes. By 2022, 51 of 58 reserves had been evaluated; 12 received "Excellent" ratings; average management score reached 78%.

The Wildlife (Protection) Amendment Act, 2006 — shaped by the Tiger Task Force Report (Joining the Dots, 2005, chaired by Sunita Narain) — restructured India's tiger conservation governance significantly, creating two new statutory bodies.

• National Tiger Conservation Authority (NTCA): Statutory body under Section 38L of WPA, 1972. Chaired by the Union Minister for Environment; includes MPs, senior officials and domain experts. Approves Tiger Conservation Plans, issues SOPs for reserve management, monitors MEE and guides financial allocation.
• Wildlife Crime Control Bureau (WCCB): Statutory body under MoEFCC for intelligence-based anti-poaching operations and inter-agency coordination (CBI, customs, Interpol).
• Tiger Task Force (2005): Constituted after the Sariska crisis (2004–05), when tigers were found locally extinct in Sariska Tiger Reserve, Rajasthan despite it being a protected area. The Task Force's Joining the Dots report recommended transparency, community participation and stronger institutional support — directly leading to the 2006 legislative overhaul.
• Cooperative federalism dimension: Tiger conservation in India is a Concurrent List subject. The Centre funds and frames policy via Project Tiger (CSS); States implement, staff and manage individual reserves. This division — and its coordination challenges — is a recurring UPSC theme.

• Global Tiger Forum (GTF): The world's only intergovernmental body dedicated exclusively to tiger conservation. Founded in 1994 after the CITES CoP, headquartered in New Delhi. Members: Bangladesh, Bhutan, Cambodia, China, India, Indonesia, Lao PDR, Malaysia, Myanmar, Nepal, Russia, Thailand, Vietnam.
• International Big Cat Alliance (IBCA): India-initiated global coalition covering seven big cats — tiger, lion, leopard, snow leopard, cheetah, jaguar, puma. Union Cabinet approved its establishment on 12 March 2024, with Secretariat in India. Currently has 95 member countries and organisations.
• Conservation Assured Tiger Standards (CA|TS): Global certification for effective tiger conservation area management. Launched at the 1st Asian Ministerial Conference on Tiger Conservation, Japan, 2013. India has 23 accredited tiger reserves — the largest national tally globally.
• St. Petersburg Declaration (2010): At the International Tiger Forum, leaders of 13 tiger-range countries adopted the Tx2 goal — to double the global wild tiger population from ~3,200 (2010) to ~6,400 by 2022. India achieved its own doubling target by 2018.
• ITHCP: IUCN's Integrated Tiger Habitat Conservation Programme, funded by the German Government through KfW Development Bank. India participates in sub-programmes covering priority tiger landscapes across South and Southeast Asia.

• Human-wildlife conflict: As tiger populations recover and expand beyond core reserve boundaries, conflict with farming and pastoral communities increases — particularly in buffer zones and corridors where land use overlaps with wildlife movement. States like Maharashtra, Uttarakhand and MP report rising annual conflict incidents.
• Corridor fragmentation: Linear infrastructure (highways, railways, canals) fragments wildlife corridors that connect isolated tiger populations. The Pench-Kanha corridor and the Terai Arc Landscape are under particular infrastructure pressure. Without genetic connectivity, small isolated populations face inbreeding depression.
• Relocation of forest communities: Core area consolidation requires voluntary relocation of villages from Critical Tiger Habitats. Compensation packages under the Forest Rights Act, 2006 and WPA provisions have been criticised for delays and inadequate rehabilitation — raising equity and constitutional concerns (Article 19 and forest-dweller rights).
• Prey base depletion: Several tiger reserves suffer from insufficient prey populations (ungulates), limiting tiger density. The 2022 AITE specifically included India's first national ungulate survey — recognising this as a limiting factor.
• Poaching networks: Despite WCCB's operations, demand from East Asian traditional medicine markets sustains organised poaching syndicates. Tiger parts (bones, skin) continue to command high black-market prices internationally.
