Abstract:

This study aimed to determine the status of wildlife in An’nanba Wild Camel National Nature Reserve and provide substantial data for diversity conservation.From January 2020 to March 2023,we deployed camera trapping to investigate the diversity of wildlife at water sources in An’nanba,Gansu province,China.We obtained 3 303 photographs of single animals(out of 18 773 total detections)among 11 443 camera-trap days at seven water sources,and identified 17 mammal species(representing to 9 families and 4 orders),and 32 bird species(representing to 12 families and 7 orders).1)Among species,ten of them are listed as the first class in the key protected wild animals of national importance and eighteen are listed as the second class.Twenty-four wildlife species were evaluated as Near Threatened or above by the Red List of China’s Biodiversity.2)The Shannon-Wiener diversity index of the mammal and bird community is 2.67 and 3.03,respectively,and the Pielou evenness index of mammal and bird community is 0.65 and 0.62,respectively.3)Based on the relative abundance index(I_RA),Gazella yarkandensis(99.54),Camelus ferus(53.57),Panthera uncia(35.22),Aegypius monachus(15.64),and Pseudois nayaur(13.81)were ranked as the top most abundant mammals and bird’s species.Our results provided a baseline of the wildlife resource in An’nanba Wild Camel National Nature Reserve,which is essential for biodiversity conservation and long-term monitoring in this area.
