The snow leopard, also known as the ounce, is a felid in the genus Panthera native to the mountain ranges of Central and South Asia. It is listed as Vulnerable on the IUCN Red List because the global population is estimated to number less than 10,000 mature individuals, and is expected to decline about 10% by 2040. It is threatened by poaching and habitat destruction following infrastructural developments. It inhabits alpine and subalpine zones at elevations from 3,000 to 4,500 m, ranging from eastern Afghanistan, the Himalayas and the Tibetan Plateau, to southern Siberia, Mongolia, and western China. In the northern part of its range, it also lives at lower elevations.
