Range DescriptionKnowledge of the distribution of C. hispidus has always been limited. The historic range of the species extended along the foothill region of the southern Himalayas from Uttar Pradesh through southern Nepal, the northern region of West Bengal to Assam, and into Bangladesh as far south as Dacca (Bell et al. 1990). The current distribution in South Asia is sporadic, including the countries of Bangladesh, India, Nepal, and possibly Bhutan (Jordan et al. 2005). The extent of occurrence of C. hispidus is estimated to be between 5,000 and 20,000 km², and the area of occupancy is estimated to be between 11 and 500 km², in highly fragmented populations (Jordan et al. 2005). It occurs at elevations ranging from 100-250 m (Jordan et al. 2005).
