Context: The greater one-horned rhinoceros is an important ecological and cultural component of the Brahmaputra floodplains and Terai grasslands.
India is seeking to consolidate existing rhino populations while expanding the species into suitable parts of its historical range.
Rhino conservation is closely linked with grassland restoration, wetland conservation, climate resilience and community participation.
Greater One-Horned Rhino in India
Historically, the greater one-horned rhinoceros occupied large parts of the northern Indian subcontinent, particularly along the Indus, Ganga and Brahmaputra river systems.
Its present wild population in India is concentrated mainly in Assam, Uttar Pradesh and West Bengal.
The population has recovered significantly, increasing from around 1,500 in the 1980s to more than 4,000 by September 2024.
Conservation policy is increasingly shifting from protecting existing concentrations to establishing secure populations across suitable parts of the species’ historical range.
National Conservation Strategy for Rhinoceros
The National Conservation Strategy for the Rhinoceros, launched in 2019, provides the framework for long-term rhino conservation.
Its key objectives include strengthening existing populations, restoring suitable former habitats, maintaining genetic security and habitat connectivity, scientifically planned translocations and climate-resilient conservation.
The approach therefore combines species protection with habitat restoration and population expansion.
Rhino Conservation Programme: Phase I (2026–2031)
The proposed five-year Phase I (2026–2031), with support through the National CAMPA Authority, brings together Assam, Arunachal Pradesh, Bihar, Uttar Pradesh and West Bengal.
It focuses on scientific monitoring, protection, habitat restoration, management, translocation planning, human–wildlife coexistence and capacity building.
The programme aims to consolidate existing populations while supporting expansion into suitable areas, particularly in Bihar and Arunachal Pradesh.
Rhino Conservation and Grassland Ecology
Rhino habitats also support swamp deer, wild buffalo, elephants, tigers, grassland birds and several smaller species.
Grasslands are dynamic ecosystems, rather than static landscapes, and require active scientific management.
Inappropriate ecological succession, habitat degradation and the spread of invasive alien species can reduce grassland quality.
The Rhino Conservation Action Plan provides for mapping grasslands and wetlands, identifying invasive species, prioritising areas for intensive restoration and developing protected-area-specific management protocols.
Climate Change and Rhino Habitats
Flooding is a natural ecological process in landscapes such as Kaziranga, but increasing frequency and intensity of extreme climatic events can create additional conservation pressures.
Conservation planning therefore needs to maintain access to higher ground, secure ecological connectivity and protect animal dispersal routes.
Habitat management must incorporate climate resilience into long-term rhino conservation.
Role of Technology and Field Capacity
Modern technologies can strengthen conservation through surveillance, spatial monitoring, veterinary diagnostics, genetic tools and decision-support systems.
However, technology cannot replace forest guards, watchers, mahouts, veterinarians and field officers who undertake day-to-day protection and management.
Effective conservation therefore requires a combination of technology, field-based expertise and institutional capacity.
Community Participation
Communities living around rhino habitats are important stakeholders in long-term conservation.
Conservation needs to be treated as a shared enterprise involving local communities, rather than solely as a government activity.
Human–wildlife coexistence and community participation are therefore integral components of the conservation strategy.
International Cooperation
Rhino conservation also requires cooperation across national boundaries because several Asian rhino species and their habitats extend across countries.
At the Second Asian Rhino Range States Conservation Meeting in New Delhi in 2019, India, Bhutan, Indonesia, Malaysia and Nepal adopted the New Delhi Declaration to strengthen cooperation for Asian rhinoceros conservation.
India and rhino-bearing States have continued to work within this broader cooperative framework.
Way Forward
Conservation should integrate species recovery with grassland and wetland restoration.
Scientific mapping and monitoring should guide habitat restoration and invasive-species management.
Conservation landscapes should be made more resilient through connectivity, dispersal routes and access to elevated areas during extreme floods.
Technology should complement, rather than replace, trained field personnel and local ecological knowledge.
Greater participation of local communities and continued inter-State and international cooperation are essential for securing the species’ long-term future.
Conclusion: The recovery of India’s rhino population demonstrates the value of sustained conservation efforts. Securing its future requires protecting not merely the species, but the grasslands, wetlands, rivers, forests and communities that constitute its ecological landscape.
Greater One-Horned Rhinoceros
The greater one-horned rhinoceros is also known as the Indian rhinoceros.
It is associated particularly with riverine grasslands, floodplains and wetlands of the Indian subcontinent.
Habitat connectivity and availability of suitable grasslands are critical for maintaining viable populations and enabling range expansion.
Comprehensive Assessment of Indian Grasslands
A five-year Comprehensive Assessment of Indian Grasslands (2026–2031) is proposed to assess the condition and ecological value of India’s grasslands.
It will be implemented by the Wildlife Institute of India (WII), Indian Council of Forestry Research and Education (ICFRE) and Forest Survey of India (FSI).
The assessment will examine grassland extent, ecological condition, biodiversity, degradation, ecosystem services and carbon potential.
Its outputs will include a National Grassland Atlas, identification of restoration priorities and long-term management guidelines.
