Context:

• The Greater One-Horned Rhinoceros (Rhinoceros unicornis) is an iconic species of India’s Brahmaputra and Terai floodplains and grasslands.
• Historically, its range extended across the northern Indian subcontinent along the Indus, Ganga and Brahmaputra river systems. Today, wild populations in India are concentrated mainly in Assam, Uttar Pradesh and West Bengal.
• India’s conservation approach is increasingly shifting from merely protecting existing rhino populations to expanding the species across suitable parts of its historical range.

From Protection to Population Recovery:

• Rhino conservation in India is fundamentally a story of recovery. The population has increased by nearly 170% — from around 1,500 animals to more than 4,000 by September 2024.
• To consolidate this recovery, the National Conservation Strategy for the Greater One-Horned Rhinoceros (2019) provides a long-term framework based on -
  • Strengthening existing populations.
  • Restoring suitable former habitats.
  • Maintaining genetic security and habitat connectivity.
  • Scientifically planned translocations.
  • Building climate resilience into conservation planning.
• Phase I - 2026–2031:
  • The proposed five-year Phase I programme, with ₹77.39 crore in support through the National CAMPA Authority, covers Assam, Arunachal Pradesh, Bihar, Uttar Pradesh and West Bengal.
  • Its priorities include scientific monitoring and protection, habitat restoration and management, translocation planning, community coexistence, and capacity building.
  • Expansion of rhino populations into suitable areas of Bihar and Arunachal Pradesh is also a priority.

Rhino Conservation is Equal to Ecosystem Conservation:

• The survival of the rhino is inseparable from the health of alluvial and Terai grasslands and wetlands.
• These ecosystems also support species such as swamp deer, wild buffalo, elephants, tigers and grassland birds.
• Grasslands are dynamic ecosystems and require active, science-based management to prevent habitat degradation, inappropriate ecological succession, and invasive species proliferation.
• The Rhino Conservation Action Plan therefore focuses on mapping and assessing grasslands and wetlands, identifying invasive species, prioritising restoration sites and developing Protected Area-specific management protocols.

Comprehensive Assessment of Indian Grasslands:

• A complementary five-year initiative (2026–2031), with ₹20.86 crore, will assess Indian grasslands through the Wildlife Institute of India (WII), Indian Council of Forestry Research and Education (ICFRE) and Forest Survey of India (FSI).
• It will examine grassland extent and ecological condition, biodiversity and degradation, ecosystem services, and carbon potential.
• It is expected to contribute to a National Grassland Atlas, restoration priorities and long-term management guidelines.
• This reflects a shift from species-centric conservation towards landscape-level and ecosystem-based conservation, where protecting a flagship species simultaneously safeguards wider ecological functions.

Climate Resilience and Technology:

• Flooding is a natural component of ecosystems such as Kaziranga, but increasing frequency and intensity of extreme climatic events can create additional conservation pressures.
• Future conservation therefore requires access to higher ground, ecological connectivity, protection of dispersal routes, landscape-scale habitat management, and climate-resilient conservation planning.
• Technology can further strengthen conservation through modern surveillance, spatial monitoring, veterinary diagnostics, genetic tools and decision-support systems.
• However, technology cannot replace frontline personnel — forest guards, watchers, mahouts, veterinarians and field officers — who remain the foundation of wildlife protection.

Conservation at Different Levels:

• Communities as conservation partners:
  • Long-term rhino conservation depends on communities living around rhino habitats.
  • Conservation must therefore be treated as a shared enterprise, rather than merely a government activity.
  • Community participation can help address human-wildlife conflict, strengthen local stewardship and make conservation outcomes more sustainable.
• Regional and international cooperation:
  • Rhino conservation also requires cooperation beyond administrative and national boundaries.
  • At the Second Asian Rhino Range States Conservation Meeting in New Delhi (2019), India, Bhutan, Indonesia, Malaysia and Nepal adopted the New Delhi Declaration to strengthen cooperation for Asian rhinoceros conservation.
  • Such cooperation is important for addressing shared challenges such as habitat fragmentation, illegal wildlife trade, genetic conservation and transboundary ecological connectivity.

Way Forward:

• India’s rhino recovery demonstrates that species decline is not necessarily irreversible when supported by sustained political commitment, scientific management and field-level protection.
• The conservation of the Greater One-Horned Rhinoceros ultimately extends beyond a single species.
• Protecting rhino habitats means protecting rivers, wetlands, grasslands, forests, biodiversity and local communities that form interconnected ecological landscapes.

Conclusion:

• India’s recovery of the Greater One-Horned Rhinoceros is a significant conservation achievement.
• The challenge now is to consolidate these gains while expanding populations into suitable historical habitats.
• The rhino’s recovery is a national achievement; ensuring its long-term survival is a national responsibility.
