The world's most endangered otter species known as the hairy-nosed otter (Lutra sumatrana) has been "rediscovered" in Deramakot Forest Reserve in Sabah by a collaboration of German and Malaysian researchers.
"This is great news for Sabah and shows once again how unique and fortunate we are in terms of wildlife and nature. In addition, these findings also boost the conservation of this endangered otter internationally as historically this otter was distributed throughout large parts of southeast Asia," said an elated Sabah Wildlife Department Director, Dr. Laurentius Ambu.
The last confirmed record of the hairy-nosed otter in Sabah is a museum specimen collected over a hundred years ago.
"Even over the whole island of Borneo the last record -- a road-kill from Brunei -- was 1997, over ten years ago. Therefore it was unknown to scientists if this species can be still found on Borneo," stated Andreas Wilting, the project leader of the Leibniz Institute for Zoo and Wildlife Research (IZW).
In 2008, IZW initiated the Conservation of Carnivores in Sabah (ConCaSa) project with the collaboration of SWD and Sabah Forestry Department (SFD) to study carnivores such as the Sunda clouded leopard, civets and otters in the State.
The ConCaSa project used automated camera traps that were set up in Deramakot and the surrounding forest reserves during the last two years. As the different otter species look very similar the hairy-nosed otter pictures had first to be verified by a number of experts before they were published recently by the International Union for Conservation of Nature (IUCN) Species Survival Commission journal.
In addition to capturing camera trap pictures of the endangered hairy-nosed otter, the study also confirmed the presence of all five Bornean cat species, 13 other small carnivores such as the Banded civet and the sun bear.
"These results mean that out of 25 known carnivore species in Borneo, our project, together with a Japanese researcher Hiromitsu Samejima, confirmed 20 in Deramakot. This makes Deramakot outstanding for being extremely rich in its diversity of carnivores," explained Wilting.
Besides pictures, ConCaSa also obtained the first videos footages ever taken for some species such the otter civet (Cynogale bennettii).
Since 1997, Deramakot Forest Reserve has been managed by the SFD as a sustainable logged forest with the coveted Forest Stewardship Council certification.
"These findings show that long-term sustainable forest management is of great importance for the protection of some of this country's most threatened species and of the unique biodiversity of the forests of Borneo," shared Datuk Sam Mannan the Director of the SFD.
One of the next steps in the conservation of Bornean carnivores is planned to be the 1st Borneo Carnivore Symposium [http://www.fwrc.msstate.edu/borneocarnivoresymposium/] in Kota Kinabalu, in June 2011. This symposium organized by the SWD, three IUCN/SSC Specialist Groups and the IZW will be a landmark international meeting bring together scientists, Government agencies and non-governmental organisations (NGO) working on the protection of the Bornean carnivores to ensure their survival.
