July is not only one of the busiest times of year for wildlife rangers on the Qinghai-Tibet Plateau, but also a time of great care and responsibility. Here, rangers and researchers at the Xizang Changtang National Nature Reserve, located at an altitude of 5,000 meters above sea level, observe and monitor the mass migration of Tibetan antelopes.

Some 150,000 Tibetan antelopes, also known as chiru, live high up on the plateau and migrate from Qinghai province to the Changtang reserve to birth their young.
