Jilin Wangqing National Nature Reserve, located in Wangqing County, NE China’s Jilin Province, covering 67,434 hectares, is one of the major habitats for China’s big cats. Trap clearing is one of the foresters' major task as it only takes days for wild animals caught in traps to die. With a GPS and a simple lunch in hand, the foresters will walk five kilometers per day searching for traps set by hunters. They have to look closely as some traps are made of thin wires and tied to tree branches. In winter, the traps get hidden under thick snow and pose dangers even to the forest rangers.
