Tiger Reintroduction Programme
Why in News?
The Tiger Reintroduction Programme is in the news because on October 2, 2026, a three-year-old tigress designated as T138 was successfully released into the Buxa Tiger Reserve in West Bengal.
Institutional Architecture & Project Origins
- Collaborative Framework: The initiative is executed under the Tiger Augmentation and Recovery Project (TARP), a joint collaboration since 2018 involving the Government of West Bengal, the National Tiger Conservation Authority (NTCA), and the Wildlife Institute of India (WII).
- Core Objective: The principal goal is to establish a viable, free-ranging, and breeding population of wild tigers in their historical natural range where they have gone locally extinct.
- Broader Strategy: The program aligns with India's Project Tiger framework and its commitments to the Global Tiger Recovery Programme (GTRP) and the Convention on Biological Diversity.
Details of the Translocation (T138)
- Source Habitat: The tigress was translocated from the Valmiki Tiger Reserve in Bihar.
- Terrain Match: Valmiki TR was selected because its landscape matches the Terai Arc ecosystem of Buxa. Sundarbans tigers were explicitly excluded due to drastically different mangrove habitat conditions.
- Phased Release: Initially, T138 has been placed in a 2.3-hectare enclosed area to acclimatise to the environment before she is set free into the broader reserve.
- Rigorous Monitoring: Post-release tracking relies on an intensive combination of satellite telemetry (radio-collaring), camera trapping, and ground patrolling to study her adaptation, health, and movements.
- Future Additions: Forestry officials plan to introduce two to three more tigers to Buxa in subsequent phases to build a breeding nucleus.
Buxa Tiger Reserve: Profile & Preparation
- Status: Located in northern West Bengal, Buxa was established as India's 15th tiger reserve in 1983.
- Ecological Importance: It forms a critical transboundary ecological corridor connecting the forests of North Bengal with Assam and Bhutan.
- Habitat Upgrades: Years of preparation preceded the release, including the restoration of over 380 hectares of grasslands, prey-base enrichment (introducing ungulates like chital), and the voluntary relocation of forest villages like Bhutia Basti and Gangutia to create disturbance-free core areas.
Challenges & Wider Conservation Context
- Threat Mitigation: Active hurdles include overcoming historical habitat degradation, heavy anthropogenic (human) pressures, and linear infrastructure dangers like the passing railway line and vehicular traffic.
- Human-Wildlife Conflict (HWC): Reintroducing large carnivores near human settlements risks escalating conflict, requiring robust local community partnership, smart corridor management, and rapid compensation systems for livestock losses.
- National Precedents: While India has seen immense reintroduction success in reserves like Sariska and Panna, it has also faced stark human-animal conflicts in areas like Satkosia, making meticulous field-readiness vital.
