Abstract

Abstract - The California Department of Forestry and U.S. Forest Service, Pacific Southwest Forest and Range Experiment Station have been conducting a paired watershed study on Jackson Demonstration State Forest for 24 years. The South Fork watershed phase of the study involved monitoring the impacts of road construction (1967) and selective tractor logging (1971-1973) on water and sediment discharge. The present North Fork phase of the study uses an extensive network of flumes with pumping samplers to monitor the impacts of clearcutting a portion of the North Fork utilizing upper slope road construction and cable yarding techniques. Principle objectives are to identify sediment sources through the watershed and evaluate the magnitude and movement of sediment. "Cumulative" effects of logging will be a specific concept tested as clearcutting progresses from the headwaters to the weir.
