A tigress from West Bengal's Buxa Tiger Reserve, designated BT1, was safely captured in Assam's Kokrajhar district on 3 November 2026 after travelling more than 100 km across state boundaries and approaching human settlements, Assam Minister Jayanta Mallabaruah confirmed. The successful operation involved coordinated efforts by forest departments from both states, district administration, police, and local communities.

The Journey of BT1

BT1 was released into the wild at Buxa Tiger Reserve on 2 October. Within weeks, she had crossed into Assam and entered Raimona National Park in the Bodoland Territorial Region (BTR). From 23 October onwards, the tigress continued moving through forested landscapes before edging closer to inhabited areas in Kokrajhar district, raising concerns over the safety of both the animal and nearby residents.

The Coordinated Rescue Operation

Recognising the potential risks, forest officials from West Bengal and Assam launched a joint tracking and monitoring operation. The intervention drew in district administration, law enforcement, and local communities, ultimately resulting in BT1's safe capture before a dangerous encounter could occur. Minister Mallabaruah, sharing details in a post on social media platform X, called the mission a commendable example of inter-state coordination.

'BT1 is safe, and that is what matters most,' Mallabaruah said, describing the operation as a benchmark for cross-border wildlife protection.

Why Transboundary Corridors Matter

The incident throws a spotlight on the wildlife movement corridors of Northeast India, where large mammals regularly cross protected area boundaries and state lines. Mallabaruah emphasised that wildlife does not recognise administrative limits, and that inter-state cooperation is particularly critical in landscapes where animal movement routinely extends beyond designated forests. Notably, the BT1 episode is part of a broader pattern — Bengal and Assam have seen multiple large-mammal dispersals in recent years, driven by habitat connectivity between Buxa, Raimona, and adjoining reserve forests.

Conservation Significance

Raimona National Park, declared a national park in 2021, is considered a key stronghold for tigers in Assam. BT1's movement through the corridor underscores both the ecological connectivity of the region and the urgent need for permanent transboundary monitoring protocols. Wildlife experts have long argued that single-state management plans are inadequate for large carnivores whose home ranges span multiple jurisdictions. The safe outcome in this case offers a model — however, critics argue that without formalised inter-state wildlife response frameworks, each such incident will require fresh ad-hoc coordination.

What Happens Next

It remains to be confirmed where BT1 will be relocated or re-released following her capture. Forest departments from both states are expected to assess her health before determining the next steps. The episode is likely to reinforce calls for a permanent transboundary wildlife corridor management protocol between Assam and West Bengal, an issue conservationists have flagged repeatedly in the context of Northeast India's fragmented forest landscapes.
