Abstract:

Objective: This study aims to understand the species diversity status of the mammalian and avian species in the Burhan Buda Mountain area in the central part of Qinghai Province,which belongs to the category of non-protected areas,and to provide reference for further research on species distribution on the plateau and for formulating wildlife protection and resource management plans. Method: A total of 23 infrared camera locations were deployed in the altitude range of 3 000-4 500 m in the Burhan Buda Mountain,from May to October 2017 and March to May 2019. Result: In this study,an intensive survey was conducted,with an effort of 4 703 camera days,and a total of 2 868 effective independent photographs were taken,in which 22 species of mammals belonging to 5 orders and 10 families,25 species of birds belonging to 5 orders and 12 families,and 4 domestic animal species were identified. Based on the RAI (relative abundance index),the four most abundant mammal species successively were Pseudois nayaur (6.44),Marmota himalayana (5.12),Lepus oiostolus (2.59),and Vulpes ferrilata (2.17),and the four most abundant bird species successively were Tetraogallus tibetanus (4.72),Phoenicurus ochruros (3.36),Alectoris magna (3.15) and Phoenicurus erythrogastrus(2.59). Among the detected species,there were 5 species listed as Class Istate key protected wild animals and 15 species as ClassⅡ state key protected wild animals in China. There were 6 species classified as endangered species,2 species classified as vulnerable species,and 12 species classified as near threatened species in the Red List of China's Vertebrates. There were 5 species endemic to China,including 3 species of mammals,Gervus albirostris,Cervus elaphus and Procapra picticaudata,and two avian species of Pseudopodoces humilis and Alectoris magna. Conclusion: The preliminary results reflect the current status of the mountain mammalian and avian species resources in the central of Qinghai Province,and provide a data basis for further study on long-term monitoring of biodiversity,management of grazing land and human-animal conflicts in the traditional plateau grazing areas of non-protected areas.
