STUDIES SHOW THAT LOGGING INCREASES RATES OF SOIL EROSION

FIGURE 7.18 This graph compares a nine-year average of soil losses, as measured by sediments transported in the associated streams, in two stream basins. One of the basins, Redfish, had been logged over 10% of its area and included 19 kilometers of logging roads, whereas the other basin, Laird, was unlogged and had no roads. (Data from Jordan, 2006)
