Why in news?

Marking the 18th anniversary of tiger reintroductions at Sariska Tiger Reserve (Rajasthan), the Centre released two new assessments: a roadmap for managing tigers in the years ahead, and a document distilling lessons from 12 reintroduction initiatives across the country.

The core message is a shift in focus — conservation must move beyond simply counting tiger numbers to reviving reserves that are struggling.

As India's tiger population reaches 3,682, the Centre has identified 25 priority reserves for habitat recovery, prey restoration, and targeted reintroductions.

Tiger Numbers Are Rising — But Concentrated in Pockets

• India's tiger population has grown steadily, from 1,411 in 2006 to 3,682 in 2022, across 58 tiger reserves spread over 85,000 sq km. But the headline number hides an uneven reality.
• Just 10-12 reserves account for about 36% of the total population. 12 reserves have fewer than three tigers each.
• Three reserves — Kawal, Kamlang, and Dampa — have zero tigers.
• This creates a two-sided problem. In high-density reserves, tigers disperse to forest edges, farmland, and mixed-use land, leading to human-wildlife conflict, greater dependence on livestock, and higher mortality from railways, roads, and canals.
• In low-tiger reserves, forests may be intact but prey is scarce — neither situation is ideal.

The Core Concept: Source vs. Sink Populations

• This is the analytical heart of the roadmap. Conservation is being reframed around the imbalance between two kinds of populations:
  • Source populations: reserves where habitat, prey, and tiger numbers are all high (e.g., Corbett, Bandipur, Kaziranga).
  • Sink populations: areas with no breeding tigers or poor connectivity to healthy forests.
• This unevenness threatens long-term conservation. The Centre's plan therefore calls for:
  • Consolidating source populations in 13 tiger reserves.
  • Priority interventions in at least 25 reserves, including reintroductions where fewer than five tigers remain.

Identifying 'Recipient Sites' — And Why It Matters

• Tiger population growth has held steady at about 6% annually, but the uneven spread means high-density regions bear the burden of managing dispersing tigers, conflict, and poaching — even as vast forests remain empty of tigers.
• The causes of this imbalance include forest fragmentation, tigers being discouraged from moving long distances, poor prey in sink areas, and human pressure.
• The solution lies in creating a well-connected landscape across reserves, territorial forests, and mixed-use areas to establish a metapopulation — enabling genetic exchange and reducing long-term extinction risk.
• To act on this, the National Tiger Conservation Authority (NTCA) and the Wildlife Institute of India (WII) built an index assessing each of the 58 reserves on habitat, prey, and tiger population.
• Based on this, 25 reserves were identified where at least one of these three factors is under stress.
  • The Central Indian and Eastern Ghats landscape has the largest number of reserves flagged for priority intervention.
  • The North Eastern Hills and Brahmaputra floodplains have extensive forests with strong recovery potential — if prey, protection, and connectivity improve.

Lessons from Past Reintroductions

• The second assessment reviews a decade-plus of reintroduction experience, with mixed results:
  • Sariska (2008): India's first reintroduction; first litter born in 2012.
  • Panna (MP): Reintroduced after a local wipeout; succeeded faster, with the first litter in 2010. Since 2009, ten translocations have been carried out overall.
  • Satkosia (Odisha): An acknowledged failure. The project was rejected by local communities, faced livestock-predation resentment, and one relocated male tiger was killed in a snare trap.
  • Mukundara Hills (Rajasthan): Progress was slow due to limited breeding success.
• The key takeaway: reintroduction is strictly a last resort, to be attempted only after rigorous scientific assessment of habitat, prey, protection, and — crucially — socio-economic conditions and local community acceptance.

Conclusion

• The roadmap marks a maturing of India's tiger conservation story. Having succeeded spectacularly in raising numbers — from 1,411 to 3,682 — the challenge has shifted from quantity to distribution.
• With a handful of reserves overcrowded and many others empty, the new strategy rightly targets habitat quality, prey recovery, and landscape connectivity to build a healthy metapopulation, rather than chasing headline counts.
• The reintroduction experience, from Panna's success to Satkosia's failure, underlines a vital lesson: ecological science alone is not enough — community acceptance and socio-economic realities ultimately decide whether tigers can return.
• Reintroduction, as the Centre stresses, must remain a carefully judged last resort.
