Forest Soil Disturbance 0 = No compaction, depressions, displaced forest floor (FF)/soil displacement and erosion 1 = slight compaction, faint depressions, FF intact, slight soil structure (SS) change (crumbly to platy), slight erosion 2 = Compaction and depressions moderately deep, FF partially intact or missing, SS change continuous, erosion moderate 3 = Compaction and depressions deep, FF missing, SS change continuous-deep, erosion severe
