An international team of scientists and conservationists has identified the Borneo population of Asian elephants as a distinct subspecies requiring special protection.

The animals are genetically distinct from all other elephant populations, having separated from them tens to several hundreds of thousands of years ago. The elephants are distinguished by their small size, with males growing to some 2.5 m in height compared to 3 m on the mainland. The team also showed that their skulls differ in shape, giving them a wider face than other Asian elephants.

Vivek Menon, Chair ������ϲʿ�������ֳ�ֱ�� SSC Asian Elephant Specialist Group (AsESG) said "I am pleased that key members of the AsESG have catalysed the listing of the Bornean elephant on the ������ϲʿ�������ֳ�ֱ�� Red List for the very first time. This range-restricted taxon has never been listed before and this assessment of its threat should spur its conservation by Malaysia and Indonesia and direct conservation focus to it in terms of resources and science.” 

“Conserving biodiversity means conserving natural variation at all levels – not only different species but also unique populations within species. The distinctiveness of the Borneo elephant in both appearance and genetics warrants its recognition as a separate subspecies, Elephas maximus borneensis. In conservation terms, it is an Evolutionary Significant Unit, whose loss would diminish both local and global biodiversity,” said Professor Adrian Lister of London’s Natural History Museum, who took part in the study.

Dr. Cheryl Cheah of WWF-Malaysia, another member of the assessment team, indicated, "As a distinct subspecies, these elephants are unique to the island of Borneo and part of our natural heritage. Their classification as Endangered underscores the urgency of collaborative conservation actions such as the management of human-elephant conflict and coexistence, and the prevention of further habitat loss and fragmentation – both of which are crucial for safeguarding their future survival."

The was undertaken by the Asian Elephant Specialist Group of the ������ϲʿ�������ֳ�ֱ�� Species Survival Commission (AsESG), chaired by Prof. Adrian Lister, Natural History Museum, UK. Other participants were:

• Mr. Vivek Menon, Chair, ������ϲʿ�������ֳ�ֱ�� SSC AsESG, India.
• Dr. Marc Ancrenaz, Hutan, Malaysia.
• Dr. Cheryl Cheah, World Wildlife Fund, Malaysia.
• Dr. Prithiviraj Fernando, Centre for Conservation and Research, Sri Lanka.
• Prof. Benoit Goossens, Sabah Wildlife Dept, Malaysia, and Cardiff University, UK.
• Prof. Adrian Lister, Natural History Museum, UK.
• Dr. Elizabeth McLean, Independent Researcher, UK.
• Dr. Nurzhafarina Othman, Project Seratu Aatai, Malaysia.
• Dr. Wishnu Sukmantoro, Forest and Wildlife Society, Indonesia.
• Dr. T.N.C. Vidya, Jawaharlal Nehru Centre for Advanced Scientific Research, India.

An urgent need is the establishment of wildlife corridors through the vast oil palm plantations, joining the forested patches and allowing the elephants to roam more widely, access more food, and mingle to preserve their genetic diversity.

Both the Malaysian and Indonesian governments have action plans for the conservation of Borneo’s elephants, but they face many challenges. The ������ϲʿ�������ֳ�ֱ�� Red List now provides international recognition of Borneo’s elephants as a unique and Endangered subspecies, providing a strong impetus for their conservation. To secure the future of these unique animals, it is essential to protect and expand their forest habitats, support local communities in minimising conflict with elephants, and enforce anti-poaching measures.
