Physical description 

Sumatran elephants are the smallest of the Asian elephants. Males rarely develop long tusks, while those of adult females may be so short that they are hidden by the upper lip. This elephant can live up to 70 years in captivity.

Size: 1.7-2.6 m at the shoulder

Colour: Lightest of all Asian elephants

Living close to rivers

Sumatran elephants are found in lowland forest close to rivers, although they may also be found in hill forests on a seasonal basis.

Diet
The Sumatran elephant feeds on green vegetation and may eat up to 200 kg of food a day, namely bananas, ginger, young bamboo and leaves of a variety of vines.

Population & distribution

Sumatran elephants were once widespread on Sumatra.  Today, however, the subspecies only survives highly fragmented populations.  Within the last 25 years, the elephants have lost 70% of their habitat.

What are the main threats? 

As for all subspecies of Asian elephants, the Sumatran elephant is threatened by poaching and habitat loss.  According to IUCN, 85% of the animal's remaining habitat is unprotected and likely to be converted for agriculture or other purposes.

Specific problems are associated with forest conversion to plantation development. As forests shrink, elephants are increasingly closer to fields and cultivated land, generating conflict with humans that often results in the death of the elephants by poisoning or capture, as well as economic losses to humans.

What is WWF doing?

We are working with partners in Sumatra to prevent destruction of forest habitat and secure well-managed protected areas and wider forest landscapes connected by corridors.

Our work to conserve Sumatran elephant habitat focuses on the island's central Riau province - an area with one of the fastest rates of deforestation in Indonesia.

By carrying out research on elephants and the nature of the conflicts, and working with local communities and companies, WWF is developing solutions that ensure living space for both humans and elephants.

Successes to date include:
