Until a few thousand years ago Borneo hosted at least 3 species of rhinoceros. The first rhino to become extinct was the Indian Rhinoceros (bottom) followed by the Javan Rhinoceros (middle). The Sumatran Rhinoceros (top) is currently on the verge of extinction in Borneo with only one captive individual (Iman) left in Sabah.
The preferred diet of the 3 species of rhinoceros that used to occur in Borneo is well known. The Indian Rhino is a”grazer” which feeds mainly on grass but also eats woody fruit and leaves. The Javan and Sumatran Rhinos are “browsers” that feed on shrubs and leaves but also eat fruit.
However the most detailed information on the diet of the Sumatran Rhino has been collected by Dr Zainal Zahari Zainuddin the vet who is charge of the Borneo Rhino Alliance (BORA) compound at Tabin in Sabah.
The BORA compound currently (May 2018) houses two female Sumatran Rhinos, Putung and Iman. These two rhinos are allowed to roam free in a large shady paddock but are given supplementary food twice a day including horse pellets, local fruit and a wide variety of leaves from over 100 species of secondary forest shrubs and climbers that grow wild at Tabin. In addition BORA has established a rhino orchard to grow the rhino’s most preferred food plants.
