Wild felid diversity and activity patterns in Sabangau peat-swamp forest, Indonesian Borneo
2011  Oryx (45): 119-124

A study to identify the felid biodiversity of the Sabangau Forest, Central Kalimantan, Indonesia, was initiated in May 2008 and involved continuous sampling until October 2009. A total of 44 cameras in 27 locations were used and 5,777 functional trap nights (of 6,542 survey nights) resulted in confirmed sightings of the Sunda clouded leopard _Neofelis nebulosa_, leopard cat _Prionailurus bengalensis_, marbled cat _Pardofelis marmorata_ and flat-headed cat _Prionailurus planiceps_, representing four of the five wild felids of Borneo. The long-term use of fixed and roving cameras provided insight into the movements, occurrence and activity patterns of these elusive felids within a disturbed peat-swamp forest. In an area of 145 km2 (including buffer) the clouded leopard was the most commonly photographed felid (22 photo-captures of 53 total captures), followed by the leopard cat (21), flat-headed cat (7) and marbled cat (3). A total of 231 camera-trap nights were required to obtain the first photograph of a felid, the leopard cat, 704 for the clouded leopard, 3,498 for the flat-headed cat, and 5,423 (476 calendar days) for the marbled cat. A female clouded leopard was not photographed until 5,764 trap nights. This highlights the importance of long-term camera-trapping studies to maximize capture probability of these elusive felids and especially to account for potential differences in home range size and use by clouded leopard males and females.
