N2 - Habitat loss and fragmentation due to anthropogenic pressure have a detrimental impact on the long-term population viability of endangered species, especially for snow leopards(Panthera uncia)inhabiting plateau mountains. To evaluate the potential distribution and habitat quality for snow leopards in the Tianshan Mountains, 78 snow leopard presence records were collected covering an area of 2 425 km2 in central Tianshan Mountains from November 2018 to June 2019.Eight species distribution models of snow leopard habitat selection were simulated. The results indicated that topographic roughness and altitude were the major factors influencing snow leopard distribution in the study area. Snow leopards preferentially occur in areas with topographic roughness greater than 70 and at altitudes range from 1 700-2 900 m.Ensemble model prediction results indicated that suitable habitat is concentrated between the west of Usu City and Banfanggou. This study obtained the potential distribution area of snow leopards in central Tianshan Mountains and evaluated the influence of environmental factors on it based on field investigation and model analysis. The study provides valuable baseline knowledge in the context of transboundary snow leopard conservation in the Tianshan Mountains.
