Preliminary surveys of wild animals using infrared camera in Wanglang National Nature Reserve, Sichuan Province

: We used infrared camera to monitor wild animals in Wanglang National Nature Reserve. Our goal was to estimate species diversity, and 5. The ), and blue eared-pheasant ( Crossoptilon auritum ) had the lowest relative abundance values (all < 1). In summary, we found camera-trapping to be an effective method for wildlife survey. Our findings suggest that less abun-dant species need more camera trapping effort. Nature reserves are important for protecting habitats of en-dangered species.
