ABSTRACT:
The Pennsylvania Department of Environmental Resources, Bureau of Forestry, developed a set of best management practices (BMPs) to limit and/or control non-point-source pollution from silvicultural activities. Nonpoint-source pollution in a forested watershed is characterized by changes in stream temperature, turbidity/sediment levels, and nutrient concentrations and export. A watershed study conducted on the Leading Ridge Experimental Watersheds in central Pennsylvania suggested that the BMPs were effective in controlling nonpoint-source pollution from a 44.5-hectare commercial clearcut. Slight increases in stream temperature, turbidity, and nitrate and potassium concentrations were observed, but these increases did not exceed drinking water standards.
