Evaluating Soil Risks Associated with Severe Wildfire and Ground-based Logging

…from the Western Wildland Environment Threat Assessment Center, US Forest Service…

“A logic-based analysis of forested soil polygons on the Okanogan-Wenatchee National Forest was designed and implemented with the Ecosystem Management Decision Support System (2, 3) to evaluate risks to soil properties and productivity associated with moderate to severe wildfire and unmitigated use of ground-based logging equipment. Soil and related data are from standard National Cooperative Soil Surveys. The logic-based model developed for this study captures the knowledge of two senior soil scientists (Miller and Meurisse collaborators in this study) with a collective experience of over 70 years in soils field work and research. Adequate GIS data to support such analysis are not always available, so we also developed a companion model for interactive use on field-going PCs. The interactive model allows users to assess individual soil units in the field.”
