The usual suspects... A female leopard cat and her kitten, photographed close to
the border with an oil palm plantation. Leopard cats were the only species of
wild cat recorded in this forest.
Rather worryingly our camera trap survey of the Kabili-Sepliok Forest Reserve has failed to detect the Sunda clouded leopard. Is this a true reflection of the localised extinction of these felids in this small and relatively isolated forest block or simply our failure to detect what is actually there?
Camera trapping is undoubtedly a powerful research tool and can quickly produce indisputable evidence of a species’ presence in an area. Proving beyond doubt the absence of a species, however, is a rather more difficult affair, and the lack of any camera trap images obtained during a survey does not necessarily prove its absence. This is particularly true of difficult to detect species such as clouded leopards.
Stray dogs were found at multiple sites across the whole of the forest.
Could their presence be one causal factor in the absence of clouded leopards?
Although unwelcome news, this is not altogether surprising given the fact that the forests in Sepliok have been reduced to about the size of a single clouded leopard’s home range – ca 40 km2. Although unwelcome, this finding is another piece in the puzzle to understand what factors control the distribution of this felid on Borneo.
Whilst it's not great news for Sepliok's Sunda clouded leopards, a number of Bornean carnivores were detected in this forest, including leopard cats, sun bears, common and banded palm civets, and yellow throated martens (see video sequence above). Potential prey species including mouse deer, yellow muntjac, sambar deer and bearded pigs were present in apparently good numbers.
Our team will now conduct an extensive questionnaire survey of the Sabah Wildlife and Forestry Department officers working in this area, in an attempt to determine when this species was reliably last seen. Meanwhile, we have recently moved our camera traps to an area of oil palm plantation immediately to the west of Sepilok, to investigate what species are using this highly modified habitat.
