Qinghai rangers rise to meet challenges
The rangers' work includes preventing grazing in prohibited areas and other activities that are banned. They also record traces of wildlife, monitor changing conditions in lakes and wetlands, protect animals and clear up litter.
The team, which uses an app to report and record its work, is taking part in the "ecological ranger" program, launched by the authorities in Qinghai in 2012 to introduce indigenous people to ecological management and enable them to earn more. Tashi's monthly salary is 1,800 yuan ($257).
