IUCN RED LIST: Critically Endangered
The Javan Rhino is the rarest of the rhino species with 60-63 animals surviving only in Indonesia.
The last Javan rhino living in Vietnam was poached in 2010. In Indonesia, Javan rhinos live only in Java’s Ujung Kulon National Park, where the population appears to have stabilized, largely because they are guarded by Rhino Protection Units. Continuing this protection, combined with establishing a second population elsewhere in Indonesia, provides the best possible hope for the species’ survival.
- The Javan Rhino is found only in Indonesia’s Ujung Kulon National Park in west Java. Javan rhinos appear to be more adaptable feeders than other rhino species: in the tropical rain forest where the species now survives, it is a pure browser, but it possibly was a mixed feeder (both browse and grass) in other parts of its historic range.
- Longevity is unknown, but Javan rhinos probably live to 30-40 years.
- Gestation is unknown but is presumed to be approximately 15-16 months, as in other rhinos. Inter-birth intervals are unknown, but mothers probably give birth to one calf approximately every 2-3 years.
- Javan rhinos are solitary in nature and are rarely seen.
