Hidden cameras have captured images of the critically endangered Sumatran rhino on the Indonesian part of Borneo island, where it was thought to have long ago died out, the WWF said Wednesday.
Sixteen camera traps—remote-controlled cameras with motion sensors frequently used in ecological research—filmed the rhino walking through the forest and wallowing in mud in Kutai Barat, East Kalimantan province.
The footage, filmed on June 23, June 30 and August 3, is believed to show different rhinos although the WWF said confirmation of this will require further study.
There were once Sumatran rhinos all over Borneo but their numbers have dwindled dramatically and they were thought to now exist only on the Malaysian part of the island.
But the research disclosed Wednesday, a joint effort between the WWF and authorities in Kutai Barat, shows that the animal is still present on the Indonesian side of Borneo.
Borneo is the world's third-largest island and is shared between Indonesia, Malaysia and Brunei.
"This physical evidence is very important, as it forms the basis to develop and implement more comprehensive conservation efforts for the Indonesian rhinoceros," said Indonesian Forestry Minister Zulkifli Hasan.
"This finding represents the hard work of many parties, and will hopefully contribute to achieving Indonesia's target of three percent per year rhino population growth."
He urged officials and environmentalists to try and come up with a scientific estimate of the remaining Sumatran rhino population in Indonesian Borneo.
