New eyes on pandas

Wireless surveillance and infrared cameras will vastly expand data available to forest rangers and conservationists. Xu Lin reports on how this may help save the endangered animal.

For the past 32 years, forest ranger Li Xifeng's daily routine is patrolling the deep woods of Heihe National Forest Park in Zhouzhi county, Shaanxi province, to protect the habitat of wild giant pandas and prevent forest fires.

But since the end of October, Li and his colleagues can monitor the situation from their office most of the time via newly installed wireless surveillance and infrared cameras.
