Yet, their most dangerous predator comes on wheels.

To protect them from poaching, an invisible surveillance network has been built.

"The all-angle cameras can cover the entire reserve. The videos will be transferred to our station by fiber-optic cables. So, our staff can monitor and record the antelopes' behavior and movements, as well as any poaching activities," said Tseta.

China was once home to millions of Tibetan antelopes, but hunting and human encroachment on their habitat has caused their population to plummet in recent decades.

But now their number has doubled since the Hoh-Xil reserve was set up 15 years ago.

Protectionists say they will continue to keep watching out for the animals they describe as "those beautiful plateau dancers".
