At least nine snow leopards are now living in a 120-square-kilometer area of the Wolong National Nature Reserve in southwest China's Sichuan Province, according to data revealed by the reserve on Friday. /Xinhua Photo

That means Wolong has the most concentrated population density of endangered snow leopards in China, Peking University professor Li Sheng told Xinhua News Agency. /Xinhua Photo

Twenty-seven infrared cameras set up within an altitude range of 4,000 to 5,700 meters in the reserve captured images of the elusive creatures on 364 occasions in the past seven months. /Xinhua Photo

Restricted to the high mountains of central and south Asia, snow leopards are listed as endangered by the International Union for Conservation of Nature. The World Wildlife Fund estimates that fewer than 4,000 individuals are living in the wild, and their numbers are declining due to habitat loss, poaching and the impact of climate change. /Chinanews Photo
