Population & distribution
Previous population & distribution
The Javan rhino historically roamed from north-eastern India through Myanmar, Thailand, Cambodia, Lao PDR, Vietnam, and the Indonesian islands of Sumatra and Java.
Historically there were three subspecies:
- Indonesian Javan rhinoceros (Rhinoceros sondaicus sondaicus)
- Vietnamese Javan rhinoceros (Rhinoceros sondaicus annamiticus)
- Rhinoceros sondaicus inermis
Most Javan rhino populations, and at least one species (R. s. inermis
, once found in Bengal, Assam and Myanmar), have disappeared in the last 150 years.
Current population & distribution
Until recently, only one population of one subspecies was known to survive: fewer than 50 Indonesian Javan rhinos on the Ujung Kulon peninsula
in western Java, Indonesia. The population appears stable, but not growing.
The Vietnamese Javan rhino was feared extinct until the 1980s, when a population of less then 10 animals was discovered clinging to survival in an unprotected forest in Vietnam. The area later became Cat Tien National Park
However, after a poaching incident in 2010, the Javan rhino is now officially extinct in Vietnam.
It is possible that other scattered remnant populations exist in Thailand and Indochina.
