This dataset is a spatial display of US Forest Service stumpage market appraisal zones. A zone may encompass a Region, a National Forest, a group of Ranger Districts, or combinations thereof. Each unique market appraisal zone defines a localized stumpage market. In each market area, stumpage values reflect the market value of standing trees (on the stump) prior to felling, removal, and utilization in a value-added manufacturing activity. The zone boundary is typically determined by factors including, but not limited to, manufacturing facilities, hauling distances, species yield compositions, timber quality, market area competition, and logging methods. Timber Appraisal Zone Metadata
