Tracing the pawsteps of the North China leopard
The North China leopard (Panthera pardus japonensis), one of the world's nine subspecies of leopards, is endemic to China and mainly distributed in the northern parts of the nation. Due to human activities, the species has undergone substantial range contraction and population decline.
To help protect the endangered big cat and inform its future conservation planning, researchers at Peking University's School of Life Sciences with collaborators mapped the animal's suitable habitats and examined the connectivity between its core habitats.
Their findings have recently been published in Landscape Ecology, titled "Big cats persisting in human-dominated landscape: Habitat suitability and connectivity of leopards in central North China."
The North China leopard is crucial to the ecosystem in North China as it is an apex predator and the only large carnivore in the area. Due to hunting and habitat loss, its population has been dwindling, with a total population of less than 400, according to statistics.
The North China leopard is categorized as critically endangered on the IUCN Red List and Endangered (EN) on the China Red List.
Previous studies have shown that the species has been sustained at several sites in northern China, suggesting the potential for restoring the species in the human-dominated landscapes across this vast area.
The study shows that the North China leopard prefers locations with higher altitudes, higher humidity, and a lower human presence.
The habitats of the big cat are highly fragmented, with the research identifying 14 habitats totaling 6,933 square kilometers and eight potential diffusion corridors totaling 57.22 kilometers. The main core habitats are located in Shanxi, Shaanxi, and the border between Gansu and Ningxia provinces.
The research concludes that the fragmentation of the North China leopard habitats is severe, and the connections between different habitats are weak.
Based on the research, it is advised to strengthen cooperation between different protected areas and administrative districts.
Surveillance of the leopard species should also be strengthened to find ways to improve the connectivity between different habitats and the effectiveness of corridors.
