Habitat Occupancy of the Critically Endangered Chinese Pangolin (Manis
pentadactyla) under Human Disturbance in an Urban Environment:
Implications for Conservation
Abstract
Globally, urban expansion has led to habitat fragmentation and altered
resource availability thus posing significant challenges for wildlife.
This study analyzed spatial distribution, habitat use patterns, and
anthropogenic impacts on habitat occupancy of the Critically Endangered
Chinese pangolin (Manis pentadactyla) in the urban landscape of Dharan
Sub-metropolitan City, Nepal. Using a single-season occupancy modelling
approach, we investigated the factors influencing the detection
probability and habitat occupancy of Chinese pangolins in 134 grids of
each 600 m × 600 m. Our study identified the role of termite mounds in
influencing detection probability, emphasizing the species’
myrmecophilous behavior. Additionally, the Human Disturbance Index (HDI)
emerged as a significant factor negatively affecting habitat occupancy
of Chinese pangolins. We observed a medium level of anthropogenic
disturbances in the grids where pangolin presence was detected. The
findings emphasize the need for targeted conservation efforts,
considering the fine-scale ecological and anthropogenic factors
impacting Chinese pangolins in urban and peri-urban areas. The results
underscore the urgency of implementing effective conservation measures
to ensure the long-term survival of Critically Endangered Chinese
pangolins in urban environments, not only in Dharan but also in similar
lowlands areas and the Churia range of Nepal.
