Abstract:

Gaoligong Mountains, known for its richest biodiversity, locates in the Indo-Burma Biodiversity Hotspot. However, our knowledge of the fauna in the alpine habitat of Mt. Gaoligong is still lacking due to complex terrain and poor accessibility. From October 2014 to June 2016, infrared cameras were established to monitor the biodiversity of mammals and birds in the alpine habitat of Mt. Gaoligong, Lushui County, Yunnan. In this survey, we selected three sample plots, North (Jinman), Central (Tingming Lake), and South (Pianma Pass), and in each sample plot, 20 cameras were established for 10,400 camera trapping days and 1,342 effective images were obtained. We identified 18 species of mammals and 44 species of birds belonging to 9 orders and 28 families, including 11 species listed as State Key Protected Wild Animals. The most abundant species was Tarsiger chrysaeus, along with Ithaginis cruentus, Zoothera mollissima, Ochotona forresti, and Ailurus fulgens. Luscinia pectoralis was recorded for the first time in Mt. Gaoligong. A one year survey at the Jinman sample plot revealed that faunal diversity in the alpine habitat had strongly seasonality, i.e. the months from May to October had much higher abundance than the other months. This was a consequence of the high immigration rate to alpine habitats during this period due to altitudinal movement and autumn migration. This survey is the first time to use infrared cameras for alpine faunal surveys at Mt Gaoligong, and the generated data provided a scientific basis for the protection and management of this nature reserve.
