Abstract: It’s very important to scientifically replenish, update and perfect the wildlife list in time for the scientific understanding the present situation of wildlife resources in the nature reserve and the targeted conservation and management. From April 2008 to September 2021, 182 effective camera monitoring sites were set up in Shenguozhuang Nature Reserve by using infrared cameras to monitor the mammals and birds in the forest. Through in-depth analysis of 91,915 infrared camera photos and video data, a total of 12 new records of species were found in the reserve, belonging to 3 orders and 6 families, including 1 mammal and 11 birds species. Among them, two species were national level II protection wild animals, namely Yellow-throated Marten (Martes flavigula) and Spotted Langhingthrush (Garrulax ocellatus). There were six species listed in the list of useful wildlife under national protection or of important economic or scientific value, including Eurasian Woodcock (Scolopax rusticola), Swinhoe’s Snipe (Gallinago megala), Spotted Langhingthrush, Black-breasted Thrush (Turdus dissimilis), Pink-rumped Rosefinch (Carpodacus waltoni) and Chinese White-browned Rosefinch (Carpodacus dubius). It’s suggested to strengthen the protection of key habitats in future conservation work, continuously use infrared cameras to carry out monitoring work and strengthen monitoring efforts in the key distribution areas of the above species. At the same time, the infrared camera data management platform should be continuously used to strengthen the scientific storage and management of monitoring data, so as to further grasp the present situation of regional wild mammal and bird species resources and dynamically accumulate more comprehensive scientific data.
