Tigress released in Buxa as West Bengal begins tiger reintroduction

On 2 October 2026, tigress T138, brought from Bihar’s Valmiki Tiger Reserve, was released into the core of Buxa Tiger Reserve. It begins West Bengal’s first tiger reintroduction programme, in a reserve with no confirmed resident tiger. Success will depend on prey, habitat, community support and landscape connectivity.

The brief in 5 cards

  1. Context1 / 5
    • A three-year-old tigress, T138, was released into the core zone of Buxa Tiger Reserve (BTR) in West Bengal on 2 October 2026, marking the start of Wildlife Week 2026.
    • She was brought from Valmiki Tiger Reserve in Bihar, chosen because its terrain and prey resemble Buxa's. This is the state's first tiger reintroduction programme.
    • The Union Environment Minister and the West Bengal Chief Minister released her jointly.
    • Buxa has had no confirmed resident tiger for years. The programme is phased, and further releases will depend on how well T138 and the habitat do.
  2. Key highlights2 / 5

    Here is the reserve at a glance.

    • Notified as a tiger reserve. 1983, India's 15th.
    • Location. Alipurduar district, West Bengal. It adjoins Bhutan's Phibsoo Wildlife Sanctuary and the Manas landscape in Assam.
    • Total area. 760.87 sq km.
    • Critical Tiger Habitat, the core. 390.58 sq km.
    • Buffer. About 370 sq km.
    • Tiger records. A minimum of 12 in the 2007 census; none recorded in the 2018 All India Tiger Estimation; one adult male photographed in December 2021; camera-trap detections in 2021, 2023 and 2026.

    The recovery effort behind the release:

    • The project. The Tiger Augmentation and Recovery Project began in 2018, run by the West Bengal Forest Department with the National Tiger Conservation Authority (NTCA) and the Wildlife Institute of India (WII).
    • Prey and habitat. More than 800 chital have been released, and about 380 hectares of grassland restored or converted.
    • People. Two villages were relocated voluntarily, according to the Union Environment Minister.
    • Natural recolonisation. The individual camera-trapped in 2023 was linked to Manas, showing that animals can still move into Buxa from nearby landscapes.
  3. Key concepts3 / 5

    1. What is the difference between reintroduction and augmentation?

    Reintroduction means releasing animals to re-establish a species where it has disappeared. Augmentation means adding animals to a population that has grown weak. Buxa's programme uses both words, because it has almost no resident tigers.

    2. What are Critical Tiger Habitat and buffer areas?

    Under the Wildlife (Protection) Act, 1972, the core of a tiger reserve is notified as Critical Tiger Habitat (CTH) and given strict protection. The buffer around it is managed to allow wildlife and local people to coexist.

    3. How is success measured?

    Releasing tigers is only the first step. The test is whether a tiger holds a territory, breeds, and sees its cubs survive; whether the population grows; and whether animals disperse and breed with tigers from linked landscapes. Seed alone is not a harvest, without soil, water and care.

  4. Way forward4 / 5
    • Prey and habitat first. A WII assessment had flagged inadequate prey as a key constraint. Releases should therefore follow prey availability, habitat quality and the results of earlier releases, rather than numerical targets.
    • Connectivity. Links with Phibsoo, Manas and Jaldapara can bring in animals naturally and prevent genetic isolation. Roads and railways can sever those links, so projects need wildlife crossings, speed limits and scientifically identified animal routes.
    • Rights-based relocation. Any relocation from Critical Tiger Habitat must be voluntary and follow the Forest Rights Act, 2006, with rehabilitation.
    • Human-wildlife conflict. A recovering tiger population can raise livestock losses, so prompt compensation, livestock protection, early-warning systems and community monitoring all matter.
    • Monitoring and local participation. T138 will be followed through telemetry, camera traps and field observation. Joint Forest Management and eco-development committees give local people a platform, and community-based ecotourism can turn conservation gains into local income.

    These are suggested measures, not approved policy.

Practice questions

  1. With reference to Buxa Tiger Reserve, consider the following statements: 1. It was notified as a tiger reserve in 1983. 2. It adjoins Bhutan’s Phibsoo Wildlife Sanctuary and the Manas landscape of Assam. 3. It is located in the Western Ghats. Which of the statements given above are correct?

    1. 1 and 2 only
    2. 1 and 3 only
    3. 2 and 3 only
    4. 1, 2 and 3
    Show answer

    Answer: A. Statements 1 and 2 are correct: Buxa was notified in 1983 as India’s 15th tiger reserve, and it adjoins Phibsoo Wildlife Sanctuary in Bhutan and the Manas landscape in Assam. Statement 3 is wrong, because Buxa lies in the Eastern Himalayan foothills of northern West Bengal, in Alipurduar district, and not in the Western Ghats.

  2. Consider the following statements about tiger reserves in India: 1. Buffer areas must be free of all human habitation. 2. Core areas of tiger reserves are notified as Critical Tiger Habitat under the Wildlife (Protection) Act, 1972. 3. The All India Tiger Estimation is carried out by the National Tiger Conservation Authority with the Wildlife Institute of India. Which of the statements given above are correct?

    3. 1 and 3 only
    4. 1, 2 and 3
    Show answer

    Answer: B. Statements 2 and 3 are correct. Statement 1 is wrong: it is the core, notified as Critical Tiger Habitat, that is kept for strict protection, while the buffer is managed precisely to allow wildlife and local people to coexist. The All India Tiger Estimation is conducted by the National Tiger Conservation Authority together with the Wildlife Institute of India.

    Difficulty: medium · statement

  3. Consider the following statements about tiger reintroduction: 1. Success is judged by whether released tigers establish territories, breed and see cubs survive. 2. Prey augmentation is unnecessary if protection is strong. 3. Connectivity with neighbouring landscapes can help prevent genetic isolation. Which of the statements given above are correct?

    1. 1 and 2 only
    2. 2 and 3 only
    3. 1 and 3 only
    4. 1, 2 and 3
    Show answer

    Answer: C. Statements 1 and 3 are correct. Statement 2 is wrong, because a tiger population cannot survive without enough prey, however strong the protection: a WII assessment had flagged inadequate prey as a key constraint at Buxa, which is why more than 800 chital were released before the tigress arrived.

Mains practice

Answer-writing practice on this article. Attempt it first, then open the hints.

  1. GS3 · 250 words

    Tiger recovery in landscapes like Buxa needs more than releasing animals. Discuss with reference to the Tiger Augmentation and Recovery Project.

    Show hints
    1. Begin with why Buxa lost its tigers: prey depletion and habitat degradation, with no tiger recorded in the 2018 All India Tiger Estimation.
    2. Describe the groundwork done since 2018, including the release of more than 800 chital and the restoration of about 380 hectares of grassland.
    3. Explain why releases are phased, with each one depending on prey, habitat quality and how earlier animals fare, rather than on a target number.
    4. Cover monitoring through telemetry, camera traps and field observation, and what counts as success: territory, breeding and cub survival.
    5. Close on connectivity with Phibsoo in Bhutan and the Manas landscape, noting the 2023 camera-trapped individual linked to Manas as evidence that natural movement still occurs.
  2. GS3 · 250 words

    Examine the challenges of balancing community rights, infrastructure and wildlife connectivity in tiger landscapes.

    Show hints
    1. Set out the rights question: relocation from Critical Tiger Habitat must be voluntary and comply with the Forest Rights Act, 2006, with proper rehabilitation.
    2. Explain how roads and railways through a corridor act as barriers, and why their alignment matters as much as their existence.
    3. Argue for mitigation that is designed in rather than added later: wildlife crossings, speed limits and routes identified scientifically.
    4. Address human-wildlife conflict as a recovering population spreads, covering livestock loss, prompt compensation and early-warning systems.
    5. Conclude on participation, using Joint Forest Management and eco-development committees and community-based ecotourism to align local incomes with conservation.
