Dooars Rani, a three-year-old tigress relocated from Bihar, was captured near Raimona National Park (Assam) and brought back to Buxa Tiger Reserve.
Project Tiger was launched in 1973 to protect tigers and their habitats.
Buxa Tiger Reserve (West Bengal) was established in 1983 under this project.
Buxa faced a decline in its tiger population due to habitat degradation, forest fragmentation and reduced prey availability.
The Tiger Augmentation and Recovery Project has been implemented since 2018 with support from the National Tiger Conservation Authority (NTCA) and Wildlife Institute of India (WII).
On October 2, 2026, Dooars Rani (T-138) was relocated from Valmiki Tiger Reserve (Bihar) and released into Buxa Tiger Reserve.
On October 25, Dooars Rani crossed into Raimona National Park, where forest officials later captured her and returned her to Buxa Tiger Reserve.
The recovery project focuses on habitat improvement, increasing prey availability and strengthening wildlife protection to restore a stable tiger population.
