Context: The first tiger reintroduction in Buxa Tiger Reserve, West Bengal marks an attempt to restore a tiger population that had disappeared from the reserve.
- The programme is being implemented by the National Tiger Conservation Authority (NTCA), West Bengal Forest Department and Wildlife Institute of India (WII).
- The article argues that preventing ecological degradation before species decline is more sustainable than relying on expensive reintroduction after populations collapse.
Buxa Tiger Reintroduction Programme
- After the NTCA found no tigers in Buxa, Dampa and Palamau Tiger Reserves by 2018, a tiger reintroduction programme was initiated.
- A Royal Bengal tigress captured in Bihar has become the first of seven tigers planned for relocation to Buxa over two years.
- Reintroduction is accompanied by ecological restoration, including chital reintroduction, canopy opening to revive grasslands and relocation of some villagers from the core area.
Ecological Challenges in Buxa
- Habitat fragmentation: Buxa is surrounded by settlements, revenue villages and tea estates, which fragment forests and wildlife corridors.
- Infrastructure pressure: A railway line threatens elephant movement, while restoration of the route to Jainti could add pressure; commercial traffic on the Bhutan–West Bengal road is another disturbance.
- Declining grasslands: Dense, closed-canopy forests have reduced grass growth, weakening the habitat available for herbivores.
- Prey scarcity: Low chital density has reduced the availability of preferred ungulate prey for tigers.
- Dietary shift: Tigers increasingly depend on goats, macaques and cattle, increasing the possibility of human-wildlife conflict.
Measures Taken Since 2018
- Prey-base restoration: Chitals have been reintroduced to strengthen the tiger's natural prey base.
- Grassland restoration: Selected forest canopies have been artificially opened to encourage grassland development.
- Conflict reduction: Villagers have been relocated from parts of the reserve's core area.
- These interventions seek to make Buxa ecologically capable of sustaining a self-reproducing tiger population, rather than merely releasing animals into an unsuitable habitat.
Preventive Conservation vs Reactive Reintroduction
- Since the launch of Project Tiger in 1973, India's traditional approach emphasised preventive conservation—protecting habitats, source populations, prey bases and wildlife corridors before populations collapse.
- Buxa, along with Sariska and Panna, represents a more reactive approach, where intervention followed severe or complete decline of tiger populations.
- Reintroduction demonstrates advanced wildlife-management capabilities but is costlier and more intervention-intensive than maintaining healthy ecosystems in the first place.
- The broader lesson is that species protection cannot substitute for ecosystem protection.
Tiger Conservation and Local Communities
- The emphasis on making tiger habitats “inviolate” can result in displacement of Adivasis and other forest-dependent communities and disruption of livelihoods.
- Relocation from core areas may reduce certain conflicts but can also raise concerns regarding rights, rehabilitation and livelihood security.
- Effective conservation therefore requires community participation in conflict management, habitat protection and livelihood planning, rather than treating local communities only as a source of disturbance.
Buxa as a Wildlife Corridor
- Buxa forms part of an international wildlife corridor, adjoining Phibsoo Wildlife Sanctuary in Bhutan to the north and Manas Tiger Reserve in Assam to the east.
- Such landscape connectivity allows tigers and other wildlife to disperse between habitats, supporting population viability and genetic exchange.
- If neighbouring forests provide greater prey availability or lower disturbance, reintroduced tigers may naturally disperse from Buxa.
What Would Constitute Success?
- Mere survival of relocated tigers would not constitute ecological success.
- Tigers must establish territories, reproduce, produce surviving cubs and form a stable population.
- Continued natural immigration and movement through connected habitats should help maintain genetic diversity.
- Long-term success should also mean that ecological degradation is identified and addressed before wildlife populations collapse.
Project Tiger
- Project Tiger: Launched in 1973 to conserve India's tiger population through habitat protection, prey-base conservation and protected-area management.
- NTCA: Statutory body constituted under the Wildlife (Protection) Act, 1972, as amended in 2006; responsible for strengthening tiger conservation and implementing Project Tiger.
- Tiger reserves: Their management involves a core/critical tiger habitat with stronger protection and a buffer area intended to promote compatible human activities and reduce pressure on core habitats.
- Wildlife corridors: Ecologically connected landscapes that facilitate movement, dispersal and genetic exchange between wildlife populations.
