Abstract
In southwest China, three major rivers, the Yangtze, Mekong and Salween, flow down from the Tibetan plateau, creating a complex topography with a diverse, little-known ungulate community. We used camera traps and multi-species occupancy modeling to determine presence/absence, habitat use and estimate species richness/occupancy. At Langdu, east of the Yangtze, we had 23 camera sites in four habitats from 4000 to 4815 m asl; at Gehuaqing in the south of Baimaxueshan Nature Reserve (BNR) between Mekong and Yangtze we had 14 sites in two habitats from 3050 to 3600 m asl. At Langdu, we photographed tufted deer Elaphodus cephalophus (Milne-Edwards 1872) most often followed by serow Capricornis milneedwardsii (David 1869) and alpine musk deer Moschus chrysogaster (Hodgson 1839). At Gehuaqing, we photographed serow most often followed by tufted deer and forest musk deer Moschus berezovskii (Flerov 1929). Tufted deer were in the most habitats, and alpine musk deer were at an elevation higher than previously reported (4815 m). The only large carnivore recorded was Asian black bear Ursus thibetanus (Cuvier 1823) leopard cats Prionailurus bengalensis (Kerr 1792) were at 4579 m asl, higher than previously documented. Langdu had higher species richness than Gehuaqing, and tufted deer had the highest occupancy at both sites. We discuss differences with another site in the north of BNR.
