Topic	Sediment: Matthews Erosion Surface from Harvest Skid Trails 1921-2000

 

Caption:  The chart above shows the computed surface erosion volumes from skid trails in harvest units for each Big River sub-basin. Matthews and Associates (2001) state: "The results suggest a peak in surface erosion coinciding with high harvest rates using high-density tractor logging methods in the 1953-1978 periods. In the most recent period, smaller volumes of surface erosion have been produced by more extensive harvest areas due to a substantial change in harvesting techniques." Estimates are generated from CDF data and aerial photographs. See Info Links for more background information and links to references.
