In this study’s analyses, we used 102 camera traps for 3,268 trap-nights. We captured 154 events of leopards, 414 of wild boar (Sus scrofa ), 942 of roe deer (Capreolus pygargus ) and 1,751 of Tolai hare (Lepus tolai ). The RAI for North China leopards in the summer (1.13) was lower than in winter (3.58), a phenomenon observed in all four species. Moreover, among the three main prey species, the RAI was highest for Tolai hare in both seasons (Table 2).
