Buxa Reserve regains its stripes with the release of a three-year-old tigress

Environment & Ecology · 4 October 2026 · Based on The Hindu (original report)

2-minute summary

A three-year-old tigress, designated T138, was successfully translocated from Bihar’s Valmiki Tiger Reserve and released into West Bengal’s Buxa Tiger Reserve in October 2026. This translocation marks the launch of a phased reintroduction programme aimed at establishing a viable, self-sustaining resident tiger population in Buxa, which has suffered from a prolonged absence of big cats due to habitat degradation, fragmentation, and a depleted prey base. The initiative is part of the Tiger Augmentation and Recovery Project, a collaborative, science-based effort implemented since 2018 by the Government of West Bengal, the National Tiger Conservation Authority (NTCA), and the Wildlife Institute of India (WII). Post-release, the tigress will be monitored closely using telemetry, camera traps, and field tracking. Ecologically, restoring tigers in Buxa is critical as it connects North Bengal with the forests of Assam and Bhutan, facilitating wildlife dispersal across a larger transboundary landscape.

Why it's in the news

A three-year-old tigress (T138) was translocated from Bihar's Valmiki Tiger Reserve and released into West Bengal's Buxa Tiger Reserve in October 2026. This event marks the beginning of a collaborative, phased effort by the NTCA, WII, and state governments to restore a resident tiger population in Buxa.

Facts to remember

• Buxa Tiger Reserve, located in West Bengal, was officially declared a tiger reserve in the year 1983.
• The Tiger Augmentation and Recovery Project in Buxa has been implemented collaboratively since 2018 by the West Bengal Government, NTCA, and the Wildlife Institute of India.
• Tigress T138, translocated to Buxa in October 2026, was sourced from the Valmiki Tiger Reserve located in Bihar.
• The National Tiger Conservation Authority (NTCA) is a statutory body under the Ministry of Environment, Forest and Climate Change, established under the Wildlife (Protection) Act, 1972.
• The NTCA has initiated tiger reintroduction and translocation programs across 12 different tiger reserves in India, including Sariska (Rajasthan) and Simlipal (Odisha).

Background and context

Buxa Tiger Reserve, situated in the Alipurduar district of West Bengal, borders Bhutan and Assam, serving as an important international corridor for Asian elephants and tigers. Historically, Buxa had a thriving tiger population, but habitat fragmentation, unchecked human encroachment, stone mining along riverbeds, and a decline in prey base led to the local extinction of resident tigers by the late 20th century. To reverse this, the Tiger Augmentation and Recovery Project was launched in 2018. Active management, including the relocation of forest villages and prey enrichment (such as releasing spotted deer), laid the groundwork for the October 2026 translocation. This effort mirrors successful and challenging reintroduction models across India, such as Sariska (Rajasthan) and Panna (Madhya Pradesh), highlighting the complex ecological and administrative coordination required for large carnivore translocation.

Constitutional provisions

• Article 48A — Directs the State to protect and improve the environment and safeguard the forests and wildlife of the country.
• Article 51A(g) — Imposes a fundamental duty on every citizen to protect and improve the natural environment, including forests, lakes, rivers, and wildlife.

Government schemes

• Project Tiger (Integrated Development of Wildlife Habitats) — The umbrella centrally sponsored scheme providing financial and technical support for tiger conservation, monitoring, and translocation projects across India.

International organisations

• Global Tiger Forum (GTF) — The only inter-governmental international body established with members from willing countries to embark on a global campaign to protect the Tiger.

Mains practice: Evaluate the ecological significance and challenges associated with active wildlife translocation programs in India, with special reference to the Tiger Augmentation and Recovery Project.

Active wildlife translocation has emerged as a crucial tool for ecological restoration in India, as demonstrated by the October 2026 translocation of tigress T138 from Bihar's Valmiki Tiger Reserve to West Bengal's Buxa Tiger Reserve under the Tiger Augmentation and Recovery Project.

• **Ecological Significance:**

1. **Restoring Apex Predators:** Reintroducing tigers helps regulate prey populations and maintains the structural integrity of the forest ecosystem, aligning with the mandate of the Wildlife (Protection) Act, 1972.

2. **Landscape Connectivity:** Buxa serves as a critical transboundary corridor connecting North Bengal with Bhutan and Assam. Establishing a resident population facilitates natural gene flow and wildlife dispersal across this larger landscape.

3. **Habitat Recovery:** The collaborative project initiated in 2018 by the NTCA and Wildlife Institute of India (WII) has driven habitat management, weed eradication, and prey-base enrichment (such as releasing spotted deer) in degraded zones.

• **Key Challenges:**

1. **Human-Wildlife Conflict:** High density of forest villages and livestock grazing in Buxa increases the risk of conflict, demanding sensitive voluntary relocation programs.

2. **Prey Base Viability:** Ensuring a sustained, high-density prey population is difficult; past failures in reserves like Sariska highlight that translocations fail without adequate prey.

3. **Post-Release Monitoring:** Tracking wide-ranging carnivores in dense, hilly terrains requires continuous telemetry and camera-trap coordination, which can be resource-intensive.

**Way Forward:**

To ensure long-term viability, the government must focus on community-led conservation by involving local Eco-Development Committees (EDCs) to mitigate conflict. Furthermore, implementing the guidelines of the National Tiger Conservation Authority (NTCA) on active management and maintaining contiguous forest corridors with Bhutan is vital.

In conclusion, scientific translocations are essential to fulfill India's commitments under SDG 15 (Life on Land) and the constitutional directive of Article 48A to protect wildlife.
