Book Description
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 larchfir forest in northwest Montana, experimentally logged with a skyline system. None of the treatments altered nutrient levels in an intermittent stream, nor were excessive amounts of nutrients lost in soil below the root zone. Under conditions on this site, skyline logging did not result in surface erosion or nutrient losses that would affect forest management.

Book Description
Excerpt from Nutrient Losses From Timber Harvesting in a Larch/Douglas-Fir Forest In western Montana, the greatest concern is for temporary nutrient depletion of young, undeveloped soils. Steep topography can accelerate nutrient loss through runoff, erosion, dust, or slump. In calculating nutrient losses resulting from harvesting, data are often not available for various species or different harvesting intensities. This study has accumulated data on the elemental content of the harvestable por tions of eight local tree species. Actual nutrient loss from the site was estimated from careful measurement of the volumes and weights of each species harvested. Harvest losses were related to the levels of available and total biologically essential elements in the soil to the limit of the root zone.
