Nutrient Losses from Timber Harvesting in a Larch/Douglas-Fir Forest

摘要

Nutrient levels as a result of experimental clearcutting, shelterwood cutting, and group selection cutting--each with three levels of harvesting intensity--were studied in a larch-fir forest in northwest Montana, experimentally logged with a skyline system. None of the treatments altered nutrient levels in an intermittent stream. Under conditions on this site, skyline logging did not result in surface erosion or nutrient losses that would affect forest management.
