Habitat fragmentation and logging affects the occurrence of the lesser mouse deer in tropical forest reserves

<p>Due to rapid urbanization, logging, and agricultural expansion, forest fragmentation is negatively affecting native wildlife populations throughout the tropics. <span>This study examined the effects of landscape and habitat characteristics on the lesser </span>mouse deer, <i>Tragulus kanchil,</i><span> populations in Peninsular Malaysia. A total of 315 camera traps were deployed in eight forest reserves. This study provides critical ecological information for managing and conserving understudied populations of <i>T. kanchil</i>. We found that the detection of <i>T. kanchil </i>was attributed to forest fragmentation.<i> </i>Forest patches had the detection of <i>T. kanchil</i> four times greater than continuous forests<i>. </i>The detection of <i>T. kanchil</i> was nearly three times higher in the peat swamp forest compared to the lowland dipterocarp forests. Surprisingly, the detection of <i>T. kanchil</i> was almost twice lower in the unlogged forests compared to logged forests. The detection of <i>T. kanchil</i> increased with the presence of trees, particularly those with DBH of 5 cm to 45 cm, canopy cover, number of saplings</span> <span>and palms, number of dead fallen trees, and distance from nearest roads. However, detection decreased with a greater number of trees with a DBH greater than 45 cm and higher elevation. We recommend that conservation stakeholders take the necessary steps to support the conservation of mouse deer species and its natural habitats regardless of whether these forests are fragmented or continuous. These steps include eradicating poaching, habitat degradation, and further deforestation.</span></p>
