We surveyed large-scale distribution of middle and large mammals by camera-trapping across three logging concessions in Borneo.

Deramakot and Tangkulap (Sabah):827 km2

Anap-Muput (Sarawak):1068 km2

Seruyan-Katingan block of SBK (Central Kalimantan):1476 km2

Borneo is one of the world’s hotspots of biodiversity. Because most of the forest is managed for timber production, the improvement of sustainable forest management (SFM) aiming to gain economical benefit while maintaining environmental integrity is considered to be a practical measure to sustain the biodiversity. Using camera trapping, we have detected that the SFM conducted in Deramakot is effective in maintaining the mammal community alongside logging operation. However, this pattern might be a specific case in this concession. To understand general patterns of logging impact on mammal populations, we conducted camera-trap surveys of the same design in two more logging concessions.

The results show common species groups sensitive to logging impacts, in addition to specific species composition in each concession. The impact of logging operations was different among the concessions according to differences in logging intensity. These findings contribute to our understanding of how the efficiency and effectiveness of SFM can be increased for biodiversity conservation.
