"Tiger reintroduction succeeds only when the causes of local extinction are addressed." Examine with reference to the recent translocation to Buxa Tiger Reserve.

On 2 October 2026, tigress T138, translocated from Valmiki Tiger Reserve (Bihar), was released into Buxa Tiger Reserve (West Bengal). This began a phased reintroduction aimed at a self-sustaining population [1][2]. Buxa shows that release is the last step; reversing what drove tigers out is the first.

Why root causes decide success

• Buxa, a tiger reserve since 1983, lost its tigers to habitat fragmentation, land-use change and prey decline [1]. A released tiger fixes none of these.
• Prey base: without enough wild prey, tigers stray and kill livestock, eroding local support.
• Connectivity: isolated reserves block dispersal and gene flow; small founder groups risk inbreeding.

What Buxa has done right

• Groundwork first: the Tiger Augmentation and Recovery Project, started by West Bengal in 2018 with NTCA and WII support, preceded the release as a "sustained, science-based effort" [1].
• Phased release: one tigress now, three more within about two months, allowing adaptive management [1].
• Monitoring: telemetry, camera traps and field tracking [1].
• Cooperative federalism: Bihar as donor; NTCA, which gives Project Tiger statutory backing [3], provides oversight.

Gaps that remain

• No public prey-density data shows recovery since 2018.
• The project is State-led; no stated corridor links to neighbouring forests, including across the Bhutan border.
• One female cannot breed; the sex and source of the next three tigers are undisclosed.
• Tourism has been promised [1] before breeding is proven, risking disturbance.

Way forward

• Publish prey estimates before further releases; NTCA–WII to release monitoring data periodically.
• Plan corridors at landscape level; assess Buxa through the All India Tiger Estimation and Management Effectiveness Evaluation.
• Diversify founder sources; expand tourism only after breeding is confirmed.

The statement largely holds. Buxa's release is credible because it followed years of habitat work, but lasting success depends on prey recovery, connectivity and transparent monitoring. If these are secured, Buxa can become a model of science-led, cooperative restoration, advancing SDG 15 (Life on Land).
