5.4 Trees in Combination with Shrubs to Control Shifting Sand

This approach is proven practice in the Horqin sandy land of NE China. Tree patches
are planted in the swales between the dunes, simultaneously with planting sand
binders (mainly shrubs) on sand dunes and later adding a pine ( Pinus sylvestris
