Greater one-horned rhino
Thanks to strict protection by government authorities in India and Nepal, the greater one-horned, or Indian, rhino has rebounded from fewer than 100 individuals to more than 3,700 today.
Beginning in 2005, IRF and our Indian Rhino Vision 2020 partners worked together to establish a new rhino population in Assam’s Manas National Park. A total of 21 animals have been born in the park since 2012, and in February 2020, two more rhinos were translocated from Kaziranga NP to Manas, bringing the population to 41 animals and growing.
IUCN Red List Status: Vulnerable & Population Increasing
- 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.
