Abstract

The Chinese Pangolin is a ‘Critically Endangered’ species, which is estimated to have declined by over 90% in the last 21 years due to increased anthropogenic activities on the species and its habitat. Only a few pieces of research on the Chinese Pangolin have been done throughout Nepal; there is little information among the mammal species of Nepal, especially on distribution and habitat preference. This study was set to assess the distribution and habitat preferences of the Chinese Pangolin in Panauti municipality, central Nepal. We identified the most preferred habitat of the Chinese Pangolin using different covariates. Its preferred habitat was found ranging 1,450–1,600 m of elevation within a moderate slope of 5–25° steepness, forested areas in west-facing slopes. The maximum number of burrows of the species were found to be distributed in open canopy (0–50 % coverage). The increase anthropogenic activities in the agricultural land and deforestation in forested land has negatively impacted the occurrence of the Chinese Pangolin. We recommend that the community-based conservation initiatives like community forestry programs should be robustly implemented in the study area for better conservation of species and habitat in the coming years.
