The chart shows environmental protection agency data for forestry practices in minnesota in the 1980's. clearcutting timber involves leveling all the trees in a forest in strips and allowing the forest to re-grow completely. selective cutting involves felling only larger timber trees and allowing smaller trees to remain until they are ready to be harvested. the epa measured soil and water loss in these areas, and also tested uncut sections of forests (controls). the epa measured water loss (water yield) and erosion (sediment loss). what conclusion can you draw from the data recorded? a) evidence of clear cutting forested areas as a source of soil erosion is inclusive. b) both clear-cutting and selective cutting cause similar amounts of water to be lost from forested areas. c) in 1984 and 1985, selective cutting conserved more water and saved more soil from erosion, than the uncut control forest. d) in all five years of the study, the control resulted in the least soil erosion as well as substantially less water loss compared to the two treatment situations.
