Abstract

Information on functional guilds and animals’ activity patterns are important in order to provide best wildlife management practices. In relation to this, camera trapping studies were conducted in Pasin Forest Management Unit (FMU) and Raplex Forest Management Unit (FMU) in Song-Kapit, Sarawak with six camera traps deployed (2019-2020) in the logged mixed dipterocarp forests. A total of 5,286 photographs were yielded from 960 camera trap days in which 17 medium to large mammal species were recorded in Pasin-Raplex FMU. Of these, Muntiacus atherodes and Hystrix crassispinis are endemic to Borneo; while Manis javanica is the only species with critically endangered status. These species were also described into four functional guilds: i) carnivores (four species); ii) herbivores (seven species); iii) omnivores (five species), and iv) insectivores (one species). In addition, detailed information on activity patterns of selected mammal species (Macaca nemestrina, Macaca fascicularis, Muntiacus spp., Viverra tangalunga, Hystrix brachyura) and functional guilds’ activity patterns were described. Overlapping coefficient between functional guilds: i) carnivores and herbivores (Dhat1=0.53); ii) herbivores and omnivores (Dhat1=0.51); and iii) carnivores and omnivores (Dhat1=0.40) were also discussed. Finally, increasing the sampling area, deploying more camera traps with continuous wildlife monitoring in these production forests are emphasised in order to collect more information for wildlife management and conservation purposes.
