Greater One-Horned Rhino
IUCN RED LIST: Vulnerable
Greater one-horned rhino numbers have recovered from fewer than 200 earlier in the 20th century to as many as 3,600 today, thanks to strict protection from Indian and Nepalese wildlife authorities.
The greater one-horned rhino is one of the two greatest success stories in rhino conservation. However, poaching pressure remains high. The species’ recovery is still precarious and depends on effective conservation efforts throughout its range.
- The greater one-horned rhino lives in northern India and southern Nepal, in riverine (floodplain) grasslands and adjacent woodland.
- Greater one-horned rhinos are grazers. When not grazing on land, animals like to immerse themselves in water, where they also graze on aquatic plants.
- Gestation lasts approximately 15-16 months, and mothers give birth to one calf every 2-3 years.
- Greater one-horned rhinos are usually solitary except for females with young. Males maintain loosely-defended territories.
Current Greater One-Horned Rhino Numbers and Distribution
There currently are approximately 3,333 greater one-horned rhinos surviving (IUCN Asian Rhino Specialist Group, 2013).
