Snow leopards’ population thriving
The number of snow leopards in the Sanjiangyuan area — the headwaters of China’s major rivers — now exceeds 1,000, experts have estimated. According to Lyu Zhi, biology conservation professor at Peking University, infrared cameras have produced more than 50,000 pictures of snow leopards over an area of 5,000 square kilometers since 2011, when the population monitoring program started. Researchers identified individual snow leopards to rule out duplicate pictures, says Zhao Xiang, director of the Sanjiangyuan project at the Beijing Shanshui Conservation Center. The count also relied on other research and laboratory analysis.
