Preliminary survey of mammals and birds diversity using camera traps in Yaoshan National Nature Reserve,Yunnan Province
In order to systematically access the species diversity of mammals and birds of Yaoshan National Nature Re-serve in Yunnan Province,we deployed 71 infrared cameras from July 2020 to October 2021 in 1 km × 1 km grid area of the reserve according to the altitude zone.During the monitoring period,a total of 17 960 camera days resulted in 8 274 independent and valid photos,including 3 810 mammals,2 958 birds,829 livestock,and 677 people.A total of 20 spe-cies of mammals,belonging to 6 orders and 12 families,and 72 species of birds,belonging to 7 orders and 20 families,were recorded.Among them,one species is listed as Class Ⅰ and 15 species as Class Ⅱ National Key Protected Wild-life in China,representing 17.39％of total species listed.The five most detected mammal species were Dremomys per-nyi,Muntiacus vaginalis,Callosciuru serythraeus,Arctonyx collaris,and Sus scrofa.The five most detected bird species were Chrysolophus amherstiae,Tragopan temminckii,Trochalopteron elliotii,Erythrogenys gravivox,Myophonus caeru-leus.Our survey detected 42 species of birds new to the reserve,including Scolopax rusticola,Psittiparus gularis,and Larvivora cyane,and 3 new species of mammals,Martes flavigula,Meles leucurus,and Petaurista caniceps.There are significant differences in bird diversity at different altitudes and habitats(P＜0.01),but there are no differences be-tween birds in different seasons(P＞0.05),and there are significant differences between animals in different seasons(P＜0.01).This study provides real image data of birds and mammals from Yaoshan National Nature Reserve,Yunnan Province,not only updates the database of species diversity in this area but also provides an objective basis for scientific protection and precise management of the reserve.
