作为“易危”物种，雪豹在中国的数量至少有4500只，约占全球总数的一半以上。

它们短小的耳朵能减少热量的散失。较浅的鼻腔空间，可在空气到达肺部前将其加热。而它们能够张开超过70度的颌骨，使它们可以轻松吃下岩羊、北山羊和白唇鹿等较大猎物。它们长而浓密的尾巴，长度和身体相当。尾巴还可以充当毯子或围巾，在雪豹躺下时覆盖住口鼻。雪豹皮毛比人类毛发密集20倍。

中国是雪豹的主要栖息地，它们生活的地区占地约110万平方公里。雪豹分布的自然栖息地为海拔2000至5000米的山区。雪豹被视为高山生态系统的晴雨表。当它们的种群数量下降时，意味着当地生态系统可能正面临压力或遭受破坏。

据国家林业和草原局表示，得益于国家公园和自然保护区等保护地的庇护作用，雪豹的核心分布区仍保持着较高程度的自然状态。
