Preliminary survey of mammal and bird diversity of Guangxi Maoershan National Nature Reserve-Based on infrared camera monitoring
Camera trapping is an important tool for monitoring terrestrial mammals and birds,and has been widely used in wildlife survey,population evaluation and behavioral ecology.We set up 51 infrared camera monitoring sites in the Maoershah National Nature Reserve to monitor large and medium-sized mammals and forest birds between July 2014 and January 2015.These monitoring sites were distributed among four habitat types and seven altitude zones.Our objective was to explore the factors influencing the diversity of mammals and birds in different habitats and at different altitudes.We identified 17 mammal species and 30 bird species,with two species as category Ⅰ state key protected wild animals and seven as category Ⅱ state key protected wild animals.Based on the relative abundance index,Edward' s long-tailed rat (Leopoldamys edwardsi),red legged yellow bellied squirrel (Dremomys pyrrhomerus),swinhoe' s striped squirrel (Tamiops swinhoei),wild boar (Sus scrofa) and Pallas' s squirrel (Callosciurus erythraeus) were ranked as the five most abundant mammal species.Silver pheasant (Lophura nycthemera),blue whistling thrush (Myophonus caeruleus) and red billed leiothrix bird (Leiothrix lutea) were ranked as the top three bird species.There were significant differences in species number,diversity and evenness indices of mammals and birds in different habitats and at different altitudes.The species number,diversity and evenness indices of mammals and birds in mixed forests were higher than those in other forests.The species number of birds was higher in 1 400-1 600 m than in other altitudes.Our results provide preliminary data for species composition of large and medium-sized mammals and forest birds,their relative abundances and spatial distributions in Maoershan,which are important for the future research and protection management.
