This damage in recent years comes from both human and natural factors. Evaluating this habitat is a key component to improve, and perhaps restore, the creature's home. The data from infrared cameras, snow leopard excrement, and snow leopard footprints was integrated with climate, terrain, and disturbance factors. The MAXENT model was used to evaluate the habitat's suitability for the snow leopard. The results show that the rainfall, altitude, and the density of bharal (blue sheep) are critical factors for the habitat's suitability. About 37% (~14000 km2) of the study area was found to be suitable. Unfortunately, not all this suitable area was protected by the nature reserve. Snow Leopard protection is most critically needed in the Shulenan Mountain and Tuolenan Mountain areas within in the Qilian Mountain range, located in the central and northwestern region of the reserve.Outside of the reserve, Sharon Beach Management Station, Tuole River Headwater Management Station, and Wahusi Management and Protection Station in the northern part of Qilian County are also critical areas needing protection for the Snow Leopard. 参考文献 相似文献 引证文献" @default.
