Abstract:

Human-wildlife conflict (HWC) related to livestock predation is one of the main challenges for snow leopard conservation in China. The Qionglai Mountains are located on the southeastern edge of the snow leopard’s range, and we used the nature reserve network which transects the central Qionglai Mountains as our study area. We collected occurrence data for snow leopards and free-range yaks from camera-trapping surveys and animal fecal DNA analysis from 2014 to 2018 and then predicted the distribution of each species using species distribution models (MaxEnt). We mapped the overlapping patches of suitable habitats between snow leopards and yaks and used the extent of habitat overlapping as the indicator of potential predation risk. The results showed that, across the seven nature reserves, the predicted suitable habitat for snow leopards and yaks is 871.14 km 2 and 988.41 km 2, respectively. The overlapping habitat between the two species is 534.47 km 2, primarily distributed in the alpine meadow area in the western part of the study area, accounting for 61.35% of snow leopard’s suitable habitat. We suggest that, when developing the management plans of these nature reserves and the newly established Giant Panda National Park, managers should consider alpine grazing a key threat to wild snow leopards and give high priority to the management of high-risk areas identified in this study. Immediate actions are needed to reduce the risk of potential HWC through interdisciplinary approaches such as grazing control and alternative livelihoods in local communities.
