Mammal and bird diversity recorded with camera traps in Gongga Mountain National Nature Reserve, Sichuan, China
2022 Biodiversity Science (30): 1-8
The Gongga Mountain National Nature Reserve lies in the global biodiversity hotspot-the Hengduan Mountains and is a priority area of biodiversity conservation in China. However, surveys of large to medium-sized mammals are insufficient in the reserve. For this reason, we conducted a camera trap survey during 2011-2018. Camera traps were placed in 97 grid cells (1 km ž 1 km per cell) with a minimum distance of over 500 m and at the altitudes of 2,672-4,764 m. Only one camera was placed in a cell during the same period. Seventy grid cells located continuously along the western slope of Mt. Gongga. A total of 20,932 independent photographs were taken over 39,881 camera-days. Thirty wild mammal species and 78 bird species were captured by camera traps. Seven other mammal species were reported by literature or occasional observation. Among them, 12 species are class I, and 28 are class II national protected animals. 11 and 12 species are listed in the CITES Appendix I and II, respectively. According to the IUCN Red List, 3 and 8 species are listed as endangered (EN) and vulnerable (VU) species, respectively. According to Red List of China's Vertebrates, 5 species are listed as Critically Endangered (CR), 5 are listed as endangered, and 11 are listed as vulnerable. Using a relative abundance index, the three most detected mammal species were the tufted deer (_Elaphodus cephalophus_, 147.39), sambar deer (_Rusa unicolor_, 66.10), and wild boar (_Sus scrofa_, 36.03); the three most detected avian species were the blood pheasant (_Ithaginis cruentus_, 14.64), white eared pheasant (_Crossoptilon crossoptilon_, 10.43), and giant laughingthrush (_Garrulax maximus_, 8.05). We provided an inventory of large to medium-sized mammals in the reserve. More in-depth investigations should be conducted in broad-leaved forest, coniferous and broad-leaved mixed forest, alpine shrub meadow, and alpine scree to survey other undetected mammals.
