摘要：Farmers and others who rememberthe Dust Bowl in the 1930s may stillhave a high regard for field wind-breaks—rows of trees and shrubsplanted to control wind damage. In the1930s, new windbreaks were establishedthroughout the northern Great Plains toreduce soil loss and improve soil pro-ductivity. Today, about 54,000 miles ofthese windbreaks remain in Minnesota,North Dakota, and South Dakota, butthat number is steadily declining. Of thistotal, Minnesota accounts for only 5,000miles, located primarily in the Red RiverValley. All other states combined have42,000 miles of windbreaks.
