Mongolia’s steppe and desert steppe zones, especially the steppes of Domod and areas of Zamyn Uud and Sainshand, belong to lands w'ith a moderate degree of w'ind erosion. Soils of the mountain regions are not affected by wind erosion. Soil erosion due to w'ind has decreased on the west side of the Great Lakes Depression, along the Khar Us Lake and in the Buyant River basin.
