Two other stations—in Yanchi County, Ningxia, and Fengning County, Hebei— also study methods for rehabilitating and improving desertified rangeland.[…]

A project on the control and rehabilitation of desertified lands in Yanchi County includes the monitoring of productivity of vegetation in 23 permanent sites (9 on sand land, 4 on lowland, 10 on high plateau); experimentation with rangeland improvement in different habitats, mainly drifting sands and degraded vegeta¬ tion; and the introduction of more than 40 species of forage plants to improve or control rangeland quality.
