Located in Sanjiangyuan National Park in Northwest China's Qinghai province, Hoh Xil is an important habitat for Tibetan antelopes, which are under first-class State protection.

Around May each year, tens of thousands of pregnant Tibetan antelopes start their migration to Hoh Xil to give birth and then leave with their offspring in late July.

The Drolkar Lake area in Hoh Xil is a crucial birth ground for the species. During migration, they have to confront extreme weather and the threat from wild animals.
