Abstract: Although designated as a protected area, our current knowledge of the diversity of wildlife species in the Matoushan National Nature Reserve, located in the central region of the Wuyi Mountain, remains relatively limited. With a view to gaining further insights on the species inhabiting the reserve, between January 2016 and December 2018, we randomly established four line transects perpendicular to the reserve's contour lines. Each of these transects spanned the distance from the base of the mountain to its summit, traversing the major habitat types characterizing the reserve. Along each transect, we installed infrared cameras (n=50, separated by distances of up to 100 m) at sites showing clear evidence of animal activity. Over a period of 34 551 camera-days, we obtained 810 and 1 724 independent images of birds and mammals, respectively, from which 13 mammal and 30 bird species were identified. Among the state key protected wild animals, ten are classed as category II species:rhesus macaque (Macaca mulatta), Chinese serow (Capricornis milneedwardsii), Asiatic black bear (Ursus thibetanus), silver pheasant (Lophura nycthemera), crested serpent-eagle (Spilornis cheela), besra sparrowhawk (Accipiter virgatus), Chinese sparrowhawk (A. soloensis), collared owlet (Glaucidium brodiei), white-necklaced partridge (Arborophila gingica), and red-headed trogon (Harpactes erythrocephalus). The white-necklaced partridge, bay woodpecker (Blythipicus pyrrhotis), and eyebrowed thrush (Turdus obscurus) were observed for the first time in the reserve. The reeves' muntjac (Muntiacus reevesi), silver pheasant, and wild boar (Sus scrofa) were identified as being the most abundant species. For more effective monitoring of wildlife within the reserve, a larger number of infrared cameras should be installed throughout the area.
