In infrared camera traps have been widely applied in biodiversity survey, which offer scientific advices for the making of conservation and management strategies. We carried out a survey on mammals and birds diversity in the Qianqingtang Area of Zhejiang’ Qingliangfeng National Nature Reserve from November 2014 to October 2016. We set up 46-51 infrared camera trap sites based on square kilometer grid method, and collected 10149 independent photos of which 88% are mammals and 12% are of birds. From the data collected, we identified 14 mammal species which belong to 5 order and 10 families, and 34 bird speciesbelong to 7 orders and 14 families. Among them, are two class I species under the State Special Protection Status: Sika deer (Cervus nippon kopschi) and Elliot’s pheasant (Syrmaticus ellioti); five class II species under State Special Protection Status-Chinese serow(Capricornis milneedwardsii), Koklass pheasant (Pucrasia macrolopha), Silver pheasant (Lophura nycthemera), Crested goshawk (Accipiter trivirgatus) and Collared scops owl (Otus lettia). Furthermore, Woodcock (Scolopax rusticola), Orange-headed thrush (Geokichla citrine), Scaly thrush (Zoothera aurea), Grey-backed thrush (Turdus hortulorum), Pale thrush (Turdus pallidus), Naumann’s thrush (Turdus naumanni) and Dusky thrush (Turdus eunomus) have been discovered within this reserve for the first time. According to the result of relative abundance index (RAI), Reeves's Muntjac (Muntiacus reevesi) (56.85), Sika deer (Cervus nippon kopschi) (16.25), and Wild boar (Sus scrofa) (13.91) ranked as the top three most abundant mammal species. Silver pheasant (Lophura nycthemera)(6.49), Rusty laughingthrush (Garrulax berthemyi) (2.43), Koklass pheasant (Pucrasia macrolopha) (1.54) ranked as top three most abundant bird species. Furthermore, t the number of mammal and bird species at elevation of 1051-1259m was higher than that of 851-1050m, and the number of species in broadleaf forest was higher than that of coniferous forest while there was no difference in number of species between broadleaf forest and coniferous and broad-leaved mixed forest . In conclusion, infrared camera traps are an effective way to survey and monitor medium-to-large mammals and some birds species. The data we gathered

could be useful in making decisions on conservation measures for Qingliangfeng National Nature Reserve.
