Camera-trapping survey of the mammal diversity in the Qilian Mountains National Nature Reserve,Gansu Province

From August 2017 to August 2018, 60 infrared cameras were set up in three monitoring sample areas in Gansu Qilian Mountains National Nature Reserve.A total of 1 619 independent wildlife photographs were collected from 14 999 camera-days.Nineteen species were identified and belonged to 5 orders and 9 families.Three domestic animal species were captured.Among the detected wildlife species, 3 species are listed as Class Ⅰ state key protected wild animals in China and five species as Class Ⅱ.Two species are endemic to China.One specie is assessed as endangered(EN), one specie near threatened(NT) and four species as vulnerable(VU) by the IUCN Red List.The fauna analysis of mammals in the reserve showed that the Palaearctic species occupies 53% and the widespread occupies 47%.These 19 species were captured when any single camera had worked for 204 days.The four highest relative abundance indexes(RAI) species were red deer(Cervus yarkandensis) (5.16), bharal(Pseudois nayaur) (2.01), Siberian roe deer(Capreolus pygargus) (0.96) and Alpine musk deer(Moschus chrysogaster) (0.71).Their activity rhythm showed that the daily activity rhythm of red deer, bharal and Alpine musk deer showed double peak with morning and night peak, while Siberian roe deer only had one morning peak.The highest relative activity intensity was in summer.Our study provides basic status of current mammal species.These findings may contribute to understanding the behavioral adaptation of the four important species, and provide baseline information for the formulation of relevant protection strategies in the reserve.
