At present，there are 14 populations of Przewalski's gazelles near Qinghai Lake，with the total number increasing from some 300 in 1994 to⑥ over 2，700，Wu added． Pastures and houses of local herders were also threatened by⑦ rising water levels. In Shinaihai Township of Hainan Tibetan Autonomous Prefecture，five houses have been submerged⑧，with 5，400 hectares of grazing land waterlogged，according to Zhaxi，head of the township.
