Medog County lies within the Eastern Himalaya biodiversity hotspot, but biodiversity in the region remains largely unexplored as there was no permanent road access until 2014. Here we present data from camera-trap surveys in 5 areas of Medog County to ascertain the occurrence and occupancy of threatened wildlife species. With a total survey effort of 4,570 trap days we detected 23 medium and large-sized terrestrial mammals and 6 pheasant species. We detected 13 wildlife species categorized as Endangered, Vulnerable or Near Threatened in the IUCN Red List. Nineteen species (65.5 %) were categorized as regionally threatened on the China Species Red List. Carnivora was the most diverse order, with 15 species recorded. Our study obtained the first camera-trap photographic evidence of Bengal tiger Panthera tigris tigris living in China. Besides Bengal tiger, we detected significant carnivores including dhole Cuon alpinus, golden cat Catopuma temminckii, marbled cat Pardofelis marmorata and mainland clouded leopard Neofelis nebulosa, highlighting the conservation value of the region. The occupancy of muntjac Muntiacus spp. was high (52.7%), indicating prey for large carnivores was abundant. Anthropogenic events also showed a high occupancy, suggesting the fauna are under threat from human disturbance. In the light of recent development in the region, conservation efforts are urgently required to stop prey depletion and habitat degradation in this priority region for conservation.
