Once it ranged over Bengal through Burma, Sumatra and Java but now only two populations remain. Up to 15 rhinos live along the Dang Nai River in Vietnam and 55 to 60 are left in Ujung Kulon National Park, their last home in Indonesia.

Badak Sumatra or Sumatran Rhino (Dicerorhinus Sumatrensis) is the only hairy and smallest of five existing species of rhinoceros. Today, there are found only in a small scattered populations living in rugged terrain in Sumatra. Its population is about 500 to 900 animals.
