Common Name: Borneo Pygmy Elephant
Scientific Name: Elephas maximus or sometimes Elephas maximus borneensis, although they have not been officially determined to be a separate subspecies from mainland Asian elephants
Habitat: Tropical and Subtropical Moist Broadleaf Forests
Location: Sabah, Borneo (northeast tip of the island), Malaysia and occasionally into East Kalimantan, Indonesia
Population: Unknown, estimated to be 1500 or fewer
Status: IUCN :Endangered CITES : Appendix I
Borneo pygmy elephants are smaller than other Asian elephants. The males may only grow to less than 2.5 meters, while other Asian elephants grow up to 3 meters. They also have babyish faces, larger ears, longer tails that reach almost to the ground and are more rotund. These elephants are also less aggressive than other Asian elephants.
Their major habitat type is concentrated in Sabah, particularly the floodplain, tributaries and the upper catchment of the Kinabatangan River - but their route has been cut off by illegal loggers and the elephants have not been there in years. They occasionally range into East Kalimantan, Indonesia.
Until recently the pygmy elephants of Borneo were believed to be a remnant population of a domesticated herd abandoned on the island by the Sultan of Sulu in the 17th century. But a 2003 DNA analysis carried out by WWF and Columbia University proved that the pygmy elephants were genetically distinct from other Asian elephants, thereby recognizing it as a likely new subspecies and emphasizing its conservation priority.
According to the DNA evidence these elephants were isolated about 300,000 years ago from their cousins on mainland Asia and Sumatra. During that period, they became smaller with relatively larger ears, longer tails and straighter tusks.
Diet
The Asian elephant is one of the largest forest herbivores in the world. A single adult can eat up to 150 kgs of vegetation everyday, feeding mostly on species of palms, grasses and wild bananas. They also require minerals which they receive from salt licks or mineral concentrations in limestone outcrops.
Threats
The primary threat to these elephants is the loss of continuous forests. Mammals of their size require large feeding grounds and viable breeding populations with sizeable male- to female ratios. Shrinking forests have also brought the elephants into more frequent contact with people, increasing human elephant conflict in the region.
The large blocks of forests they require are now being fragmented by encroachment in forest areas and conversion of natural forests into commercial plantations. Human disturbances within forests such as logging, increased agriculture, building of palm oil mills with associated settlements and hunting are rapidly breaking up contact between sub populations, as well as minimizing the areas of forests available for each small group to live and feed on.
