Abstract：The biological inventory within established protected areas is fundamental for biodiversity research and monitoring at both regional and national levels. Infrared camera- trapping technique has been widely used recently for species inventories and related assessment of terrestrial vertebrates in protected areas across the world. We conducted a camera-trapping survey to investigate the inventories of mammal and bird within Guizhou Chishui Alsophila Reserve (GCANNR) and its surrounding areas. We totally deployed 60 camera traps in three sample plots (two in the Reserve and one in outside the Reserve) using continuous1 km×1 km grids. With a total of 21 234 independent images by an extensive survey effort of 55 029 camera-days during Dec. 2016 to Dec. 2019, we identified that 21 wild mammal species belonging to 4 orders,10 families and 17 genus, and 34 wild bird species belonging to 6 orders,13 families and 29 genus. Eight species were recorded firstly in GCANNR. There were 4 mammals and 8 birds categorized as class II nationally protected wildlife, or 8 and 13 species were listed as VU and NT species, according to the Red list of China's Vertebrates. Based on relative abundance index (RAI), the top three abundant mammal species were Elaphodus cephalophus, Muntiacus reevesi, Macaca thibetana, and the three most abundant bird species were Myophonus caeruleus, Bambusicola thoracicus, Garrulax canorus. Additionally, we found that the species richness and species diversity Shannon-Wiener index (H) of animals (especially mammals) in GCANNR are greater than those of surrounding areas of GCANNR, and these indexes of birds and mammals in the core zone and buffer zone of the Reserve are higher than those in the outer buffer zone. We also found that the species richness of mammals were higher in 700 – 1 000 m elevation range, while the diversity index (H) of birds and mamamls were highest in > 1 000 m elevation ranges. Our results provided important baseline information of bird and mammal resources for further biodiversity research, as well as for optimizing management strategies and realizing long-term survey and effective protection in GCANNR.
