[00:00.96]However, the situation is improving.
[00:03.95]Anti-poaching laws are now actively enforced
[00:07.51]so every summer, female chiru can head to the birthing grounds in relative safety.
[00:25.51]Out on the plateau, new-born chiru are vulnerable to predators
[00:30.73]so the mothers must try to hide and protect them.
[00:48.22]The most recent problem faced by the chiru is the new Tibet-Qinghai railway
[00:54.35]which cuts right through their traditional migration routes.
[00:58.15]Running nearly 2,000 kilometres through some of the highest terrain on Earth
[01:02.72]the railway is an astonishing technical feat.
[01:07.12]It's too early to see its effect on the wildlife
[01:10.54]But the engineers have made efforts to incorporate underpasses
[01:14.59]where wildlife can cross the line in safety.
[01:28.94]As the modern world increasingly impacts on Tibet
[01:32.58]its traditions could be in danger of being eroded.
