Distribution and status of the Sumatran rhinoceros in Peninsular Malaysia

Abstract

Distribution and status of the Sumatran rhinoceros Dicerorhinus sumatrensis in Peninsular Malaysia were studied from 1975 to 1981. We compiled information collected from field surveys, interviews with people living near rhino areas, and the literature. Most potential rhino areas were surveyed on the ground to confirm the presence of animals, estimate numbers, and evaluate the status of the habitat. We confirmed that rhinos presently occur in ten isolated areas scattered throughout the Malay Peninsula. The number of rhinos is estimated at 50 to 75 animals with the Endau-Rompin (20–25), Taman Negara (8–12), and Sungai Dusun (4–6) areas containing the largest contiguous populations. The Sumatran rhino appears threatened with immediate extinction in Peninsular Malaysia. Excessive killing of rhinos because of the high commercial value of their body parts has greatly reduced numbers. Habitat destruction from logging and forest clearance has separated and isolated already small populations. We recommend that conservation efforts for this species in Malaysia be concentrated in the Endau-Rompin region because this population has the best chances for survival.
