Globally, urban expansion has led to habitat fragmentation and altered resource availability, thus posing significant challenges for wildlife. The Chinese pangolin (Manis pentadactyla) is a critically endangered species experiencing population decline due to illegal trade and habitat degradation. This study analyzed variables affecting habitat occupancy of Chinese pangolins using a single-season occupancy model across 134 study grids (600 m × 600 m) in peri-urban areas of Dharan Sub-Metropolitan City, eastern Nepal. We identified termite mounds as a significant key factor (top model with AICwt = 1) in the detection probability of Chinese pangolin burrows (β Termite mounds = 1.48, 95% CI = 1.07 to 1.89). Additionally, the Human Disturbance Index (HDI) emerged as the key variable for habitat use occupancy (AIC = 231.96, AICwt = 0.309), indicating a significant negative impact (β HDI = -6.555, 95% CI = -11.324 to -1.7723). We observed a mean HDI of 0.475 ± 0.04 in the grids where Chinese pangolins were detected, with higher HDI values correlating with reduced Chinese pangolin occupancy. For the long-term conservation of Chinese pangolins in urban landscapes, it is crucial to reduce anthropogenic activities and implement conservation measures to protect suitable habitats with abundant termite mounds.
