If I remember correctly, Qinghai Lake is used by the birds migrating between Europe and Asia. Many years ago, when Sudden Acute Respiratory Syndrome ("SARS") was a serious health problem in the People's Republic, scientists were worried that the birds migrating from Asia to Europe would bring SARS to Europe. Scientists wanted to capture some of these migratory birds on the shores of Qinghai Lake to test them for the virus. Pictures in the media showed a local man trying to capture these birds with nets. Other pictures showed widespread death in this migratory bird population.
During this SARS epidemic, I spent two weeks in Xining. A beautiful city with a very dry climate and a large muslim population.
