Background
This information has been reviewed by A. Christy Williams, Coordinator, WWF Asian Rhinoceros and Elephant Action Strategy.The present situation
Known populations of this rhino are small and widely scattered, its forest habitat is dwindling fast, and the threat of poaching is ever-present. Today, the wild population of the Sumatran rhino may be below 300 individuals, and so far captive breeding attempts have been unsuccessful. The species is currently found in penisular Malaysia, and on the islands of Borneo (Sabah, Malaysia) and Sumatra (Indonesia). The Borneo population is considered a distinct sub-species.
Survival priorities
If this small hairy rhino is to survive much longer, urgent measures are needed to save the forests where it still occurs. Moreover, it is imperative that trade in rhino horn and other products is halted immediately.
WWF's work
WWF is approaching the conservation of Sumatran rhinos from a number of angles including protection of habitat, strengthening anti-poaching efforts, trade monitoring of rhino horns, protected area management, and awareness programmes.
