Diversity of carnivorous mammals in Batutegi Nature Reserve, Lampung, Sumatra
The Batutegi Nature Reserve (BNR) covers an area of 58.162 ha of which 10,085 ha remain natural, with the rest utilised by surrounding communities. To ensure protection of the remaining undisturbed forest, the forest management unit Batutegi in cooperation with International Animal Rescue Indonesia conducted conservation activities in BNR for the past 10 years. In 2017, we conducted a systematic camera trap survey of animal diversity by deploying 33 cameras in grids of 2 x 2 km for a period of 11 months. Analysis of camera trapping data revealed a total of 3507 individuals belonging to 41 species with 60-minute independence of each capture was obtained. Thirteen species of carnivorous mammals were captures constituting to 8.47% of total individual animals captured. Mydaus javanensis (n = 108), Hemigalus derbyanus (n = 56) and Prionodon linsang (n = 29) were the most captured, while Panthera tigris sumatrae ranked ninth in the number of independent captures. The presence of these carnivores indicate the biodiversity richness in an area where encroachment and forest conversions have caused increasing fragmentation. The only conservation management strategy implemented in this region has been the establishment of exploitable forest and core forest zones. To mitigate the impact of habitat fragmentation, we recommend that corridors are created between the core blocks in Batutegi Protected Forest to adjacent conservation areas.
