Abstract:

Camera-trapping provides an excellent tool for biodiversity and wildlife protection research. In this study, mammals and birds in Chishui Alsophila National Nature Reserve were monitored using 20 gridded camera traps. A total of 1,936 independent images (out of 45,953 recognizable images) were collected with an extensive survey effort of 6,370 camera-days during August 2015 to August 2017. We identified 19 mammal species and 28 bird species, of which 7 species were second-class National Protected Wildlife in China. The relative abundance index (RAI: number of records per trap effort) is widely used to assess the regional species abundance. The five most abundant mammal species with highest RAIs in Chishui Alsophila National Nature Reserve were Elaphodus cephalophus, Melogale moschata, Macaca thibetana, Muntiacus reevesi, Sus scrofa, and the five most abundant bird species with highest RAIs were Myophonus caeruleus, Tragopan temminckii, Bambusicola thoracicus, Garrulax chinensis, Pomatorhinus ruficollis. Rarefaction and species accumulation curves suggest that mammal sampling asymptotes around 300 days, suggesting monitoring efforts were sufficient although bird species continued to grow over time. The results of this extensive survey provide a comprehensive diversity study of mammals and birds in Chishui Alsophila National Nature Reserve and may provide primary baseline data for biodiversity management resources.

Key words: diversity of species, Chishui Alsophila National Nature Reserve, camera trapping, species accumulation curves
