In the forests of the Wangqing National Nature Reserve, in Jilin province, one of China's most important breeding grounds for two rare species of wild animals, rangers are constantly on the move doing everything they can to make sure the denizens live in a safe and comfortable environment.

Two of these public servants are Wu Guoqing and Yan Zhiqiang, who patrol the forests each day, along with many other rangers. In commenting on his work, Wu says, "We need to keep an eye on illegal hunting and logging activities or digging wild ginseng, all of which pose a danger to wild animals, and we also monitor forest fire outbreaks and other emergencies".

In recent years, the provincial forestry dept and big-cat experts have worked together to check on the number of Siberian tigers and leopards in the reserve, which means Wu Yan join the other rangers in helping collect data. More recently, these wildlife public servants have gotten another job -- helping collect the film from the various infrared cameras installed around the reserve.
