Abstract
The Rungan – Kahayan landscape, covering ~4700 km2 in Central Kalimantan is a diverse mosaic of tropical heath (kerangas) and peat swamp forests. The mammal fauna of this region remains poorly documented, while the area has been subjected to rapid land cover changes threatening remaining forest areas. Here we describe the medium–large-sized mammal community in eight community-managed forest blocks and one forest area set aside for education purposes in this landscape. We deployed 86 camera traps across seven habitat types between April 2022 and October 2023, intending to set baselines on mammal presence and distribution within the landscape. The survey recorded 936 independent detections of 24 species, comprising six mammalian orders distributed across 14 families, including three taxa endemic to Borneo. Forest gaps and kerangas habitats recorded the highest independent detections per unit area, despite low-pole and mixed swamps being the most widespread habitat type. The presence of several protected species, including the first detection of otter-civet (Cynogale bennettii) in this area, emphasises the conservation significance of the remaining forests within the landscape. The lesser mouse deer (Tragulus kanchil) and the muntjac (Muntiacus artherodes) were frequently detected. The sambar deer (Rusa unicolor) and bearded pig (Sus barbatus)—common ungulates in lowlands, typically hunted—were rare. Our study represents the first large-scale baseline assessment of mammals in the Rungan-Kahayan landscape, highlighting its significance for animal conservation in Central Kalimantan.
