Excerpts from the report: Wind erosion seriously threatens any area of low, variable precipitation, where drought is frequent, and temperatures, evaporation, and windspeeds are high. It is the dominant problem on about 70 million acres of land in the United States—an area that includes 55 million acres of cropland, 9 million acres of rangeland, and 6 million acres of "other" land. Good farming practices, such as crop rotation and controlled grazing, adequately protect about 34 percent of this land, but specific wind-erosion control is needed on about 46 million acres. Each year about 4.8 million of these acres undergo moderate to severe damage. Wind erosion is most serious in the Great Plains, but it also occurs around the Great Lakes in Michigan, Wisconsin, and Ohio, along the eastern seaboard, in the Southeastern Coastal Areas, and in the Northwest, especially in newly irrigated areas.
