Abstract:

Aims: The leopard cat (Prionailurus bengalensis) is a small felid widespread in Asia and serves as a primary predator in North China’s temperate forest ecosystem, after the mega-carnivores such as the leopard went extinct from the region. Despite its ecological resilience and adaptivity, whether the leopard cat can survive in nearest proximity to urban Beijing remains unknown. Field surveys of the presence of leopard cats in the suburban Beijing and evaluation of the environmental factors associated with its distribution will set the stage for elucidating the pattern of human-wildlife coexistence around a megacity of China like Beijing.

Methods: From October 2022 to June 2023, we conducted 16 transect line surveys in search of leopard cats in the nearest mountainous area west of urban Beijing. The region refers to the Western Beijing Crescent Bay Mountains that covers the wilderness landmarks of Mt. Baiwang-Fragrant Hills-West Mountains-Mt. Jiufeng-Mt. Yangtai-Mt. Miaofeng-Mt. Fenghuangling-Baihujian. The presence of leopard cats was examined through non-invasive sampling of scat samples, DNA extraction, and species identification based on DNA barcoding analysis. By integrating species presence information and eight selected environmental variables, we constructed an ensemble model to assess the impact of various environmental factors on the species distribution.

Results: We validated 258 sites of leopard cat presence from cumulative 180 km trails in the Western Beijing Crescent Bay Mountains survey area. For a relatively continuous habitat, the occurrence of leopard cats was primarily influenced by anthropogenic variables, with the distance to artificial infrastructure (42.71%) and hiking intensity (20.12%) being the two primary factors. A buffer distance of at least 1,000 m from major human facility was required for a habitat to be considered suitable for leopard cats around Beijing. While the distance to artificial infrastructure displayed a positive correlation with the presence of leopard cats, hiking intensity exerted relatively little impact, suggesting the leopard cat’s tolerance to moderate human activities to certain extent.

Conclusions: The existence of a wild leopard cat population is confirmed in the mountainous area on the outskirts of Beijing, illustrating the prospect for human-wildlife co-existence around China’s capital city. This preliminary survey suggests that as far as relatively intact habitat could be preserved on a landscape scale with minimum anthropogenic disturbance, a generalist species such as the leopard cat may be ecologically resilient enough to survive in nearest proximity to an urban region.
