The North China leopard ( Panthera pardus japonesis ) is a rare leopard subspecies distributed only in China. In this study, we conducted camera-trap surveys of a North China Leopard population in Tie Qiao Shan Nature Reserve, Shanxi Province, China. We estimated population abundance and density distribution, and explored the effects of distribution of different prey populations, habitat, and anthropogenic factors on the spatial distribution of North China leopard density. Our results suggested that the North China leopard density was 4.23 individuals/100 km 2 , and that 17.98 individuals might live within the study area. The population density of the North China leopard increased with the distribution of wild boars, and, on the contrary, decreased with the distribution of roe deer. We found that habitat environmental factors and anthropogenic interference also significantly affected the population density and spatial distribution of the North China leopard. These insights informed us that in order to protect this predator, which is only distributed in China, we should adopt a comprehensive customized adaptive landscape protection strategy.

Wildlife populations are spatially controlled and undergo frequent fluctuations in abundance and site occupation. A comprehensive understanding of dynamic species processes is essential for making appropriate wildlife management plans. Here, we used a multi-season model to describe the dynamics of occupancy estimates of the carnivores: North Chinese leopard ( Panthera pardus japonensis , Gray, 1862), leopard cat ( Prionailurus bengalensis , Kerr, 1792), and red fox ( Vulpes vulpes , Linnaeus, 1758) in the Tieqiaoshan Nature Reserve, Shanxi Province, China, over a three-year study period using camera traps data. The occupancy probability of the North Chinese leopard did not markedly change with time as the occupancy equilibrium was constant or slightly enhanced. The occupancy of the leopard cat decreased with time. The occupancy equilibrium of the red fox alternately increased and decreased. However, all species presented a slight level of occupancy stability due to their small values of the rate of change in occupancy. Environmental factor and anthropogenic disturbances slightly influenced the occupancy of all species and the colonization and extirpation probability of the red fox. The colonization and extirpation for all species were relatively more strongly affected by the distances to villages and roads. Moreover, elevation increased the colonization and decreased the extirpation for the leopard cat. Species interaction factors increased with time for all species. The North Chinese leopard and the leopard cat avoided each other. The leopard cat and the red fox independently co-occurred. There was true coexistence between the North Chinese leopard and the red fox. This research confirmed that environmental factors and human perturbations are vital factors to consider in wild carnivores' conservation and management.

Livestock depredation by large carnivores is a conventional human-wildlife conflict, both at the local and regional level. Many species of wildlife have become endangered because of this conflict. In this study, an investigation of livestock depredation was conducted for the north China leopard in and around Tieqiaoshan Provincial Nature Reserve in Shanxi Province between 2015 and 2018. Data were obtained from League Cat Forest Department records. Additionally, standardized, structured, and semi-structured questionnaires were used to collect data with the help of reserve field staff. The results show that there was a significant difference ( p = 0.015) in livestock depredation in various seasons of the year; the highest depredation was recorded in spring, followed by summer. A significant difference ( p = 0.02) was observed between cattle and other livestock species, showing that more cattle were killed by the north China leopard. Most of the livestock depredation occurred during late morning and evening, likely because the leopards are crepuscular. Residents in and around the reserve suffered a high economic loss, ranging between RMB 5000 and 10,000 (USD 706.76-1413.53) per year in terms of the estimated market price of the killed livestock. The attitudes of residents towards the north China leopard vary according to the economic activities of the locals, with about 76% of the livestock keepers reporting that the leopard is "very dangerous" and 8% of the arable farmers in and around the reserve indicating that leopard is "very dangerous." We recommend that a system with local participants would ensure more effective management of human-north China leopard conflict, as it would allow local communities to take greater responsibility., Competing Interests: The authors declare no conflict of interest.
