The Sumatran rhino is one of the three rhino species found in Asia. Their population is said to have declined by about 50% since the late 1990’s. Their decline, like all other species of rhino, is due to poaching for their horn but the Sumatran rhino is also suffering due to loss of habitat. Their natural habitat is being destroyed and developed for palm oil plantations.

Unfortunately for the Sumatran rhino, their habitat is very close to China, one of the main destinations, along with Vietnam, for creating a demand for rhino horn.

The Sumatran rhino is a browser and some of their favourite food is leaves, plant tips, twigs and fruits.

The Sumatran is the smallest and hairiest of all the surviving rhinos.  It is said to be the closest living relative to the now extinct woolly rhino.
