Sumatran Rhino

Dicerorhinus sumatrensis

White Oak Conservation Center, Yulee, Florida, USA

Critically Endangered

The total population is estimated at fewer than 275 individuals, though probably more than 220. Until the early 1990's the numbers continued to decline at a rapid rate with estimated losses of 50% or more of the population per decade (Foose and van Strien 1997). Over the last decade the decrease has been halted or slowed in most of the larger populations because of better protection, but animals are still being lost in the small remnant populations.The subspecies Dicerorhinus sumatrensis sumatrensis now occurs mainly on Sumatra, where there are 170 to 230 individuals. It has its largest populations remaining in ... Read More

The two principal threats are poaching and reduced population viability. Hunting is primarily driven by the demand for the supposedly medicinal properties of rhino horns and other body parts, and many centuries of over-hunting has reduced this species to a tiny percentage of its former population and range. The species is now so reduced that there are very small numbers in each locality where it still survives. As a result, breeding activity is infrequent, successful births are uncommon in many populations, and there is a severe risk of inbreeding depression (J. Payne pers. comm.). The species is frequently stated to ... Read More
