Small group claws its way up

In 2008, the Chinese Felid Conservation Alliance began building a camera-trapping network to monitor North Chinese leopards in Shanxi province. Today, it says there are more than a dozen members of the species in the area. Xu Lin reports.

In the first scene you can see two leopards walking past in a mountain forest. Then, one pauses after it notices something - an infrared camera. It claws at it several times until it falls off its mount.

This is among the scenes captured by more than 100 infrared cameras in the central Taihang Mountains in Shanxi province.
