Description
We present results and inferences from 15 soil-monitoring projects by the USDA Forest Service (USFS) after logging in the interior Columbia River basin. Details and comments about each project are provided in separate appendixes. In general, application of past protocols overestimated the percentage of “detrimentally” disturbed soil in harvested units. Based on this past monitoring experience, we recommend changes to existing protocols, and further validation and revision of USFS numerical standards for judging change in soil quality and for defining “detrimental” soil disturbance.
