摘　　要：The Chinese Pangolin (<em>Manis pentadactyla</em>) is a “Critically Endangered” insectivorous mammal. There is a lack of information on the ecology, distribution and behavior of this species in Nepal, even though community forests in the Midhills Region of Nepal are considered to be prime habitats for the species. We conducted an ecological assessment of the habitat use of this species in nine community forests covering an area of 170.69 ha in Balthali village in Kavrepalanchok district, Nepal. We divided each forest into 50 × 50 m grids and searched for Chinese Pangolin burrows along 50 m transects in each grid. We categorized burrows into two types, new and old burrows, and recorded 10 environmental variables for each burrow. We found a total of 542 burrows, including 323 old burrows and 219 new burrows. The average width and height of a burrow opening was 21.66 ± 3.94 cm (<em>n</em> = 542) and 22.42 ± 5.02 cm (<em>n </em>= 542). The total density of burrows in the study area was 3.1 ha^{<span style="white-space:nowrap;">&#8722;</span>1}, with new burrows density of 1.2 ha^{<span style="white-space:nowrap;">&#8722;</span>1} and old burrows density of 1.8 ha^{<span style="font-size:10px;">&#8722;</span>1}. We found most burrows in sites with an elevation range of 1400 - 1500 m above sea level, gentle slopes, brown colored soil, high density of tree crown cover and undergrowth vegetation, southern exposure, within 150 m from a water source and less than 200 m from a human settlement. Our study has generated baseline data on the habitat use of Chinese Pangolin, which we hope will help in designing site-specific action plans for Chinese Pangolin conservation in Kavrepalanchok district, Nepal.The Chinese Pangolin (<em>Manis pentadactyla</em>) is a “Critically Endangered” insectivorous mammal.
