Pygmy elephant may have been introduced to Borneo from Java


KOTA KINABALU: The Borneo pygmy elephant may not be a native to the island after all.

Instead, the population may be the last survivors of the Javan elephant, which was accidentally saved from extinction by the Sultan of Sulu centuries ago, as a new publication suggests.

The origins of the pygmy elephant, found in an area extending from the northeast into the heart of Borneo, have long been shrouded in mystery.

Their looks and behaviour differ from other Asian elephants and scientists have questioned why they never dispersed to other parts of the island.

But a new paper published recently supports a long-held local belief that the elephants were brought to Borneo centuries ago by the Sultan of Sulu, now in the Philippines, and later abandoned in the jungle.

The Sulu elephants, in turn, are thought to have originated in Java.

Javan elephants became extinct some time in the period after the Europeans arrived in South-East Asia.

Elephants on Sulu, never considered native to the island, were hunted out in the 1800s.

“Elephants were shipped from place to place across Asia many hundreds of years ago, usually as gifts between rulers,” said Shim Phyau Soon, a retired Malaysian forester whose ideas on the origins of the elephants partly inspired the current research.

“It’s exciting to consider that the forest-dwelling Borneo elephants may be the last vestiges of a subspecies that went extinct on its native Java Island, in Indonesia, centuries ago,” he said.

If the Borneo pygmy elephants are in fact elephants from Java, an island more than 1,200km south of their current range, it could be the first known elephant translocation that has survived to modern times, providing scientists with critical data from a centuries-long experiment.

Scientists solved part of the mystery in 2003, when DNA testing by Columbia University and WWF ruled out the possibility that the Borneo elephants were from Sumatra or mainland Asia, where the other Asian subspecies are found, leaving either Borneo or Java as the most probable source.

The paper Origins of the Elephants Elephas Maximus L. of Borneo, published in this month’s Sarawak Museum Journal, shows there is no archaeological evidence of a long-term elephant presence on Borneo.

“Just one fertile female and one fertile male elephant, if left undisturbed in enough good habitat, could in theory end up as a population of 2,000 elephants within less than 300 years,” said Junaidi Payne of WWF, one of the paper’s co-authors.

“And that may be what happened in practice here,” he said.

There are perhaps just 1,000 of the elephants in the wild, mostly in the Malaysian state of Sabah.

WWF satellite tracking has shown they prefer the lowland habitat that is being increasingly cleared for timber, rubber and palm oil plantations.

Their possible origins in Java make them even more a conservation priority.

“If they came from Java, this fascinating story demonstrates the value of efforts to save even small populations of certain species, often thought to be doomed,” said Dr Christy Williams, coordinator of WWF’s Asian elephant and rhino programme.

“It gives us the courage to propose such undertakings with the small remaining populations of critically endangered Sumatran rhinos and Javan rhinos, by translocating a few to better habitats to increase their numbers.

“It has worked for Africa’s southern white rhinos and Indian rhinos, and now we have seen it may have worked for the Javan elephant, too,” he said. – Bernama
