This method takes the functional efficiency of soil protection into account: Under normal circumstances, a harvested deciduous coppice forest regains the function of coverage of a moderately dense forest four years after the clear-cut. Ten years after the harvesting, the C factor returns to the mature forest value .There after, it converges towards its pre-disturbance CUF value. Although coniferous forests may experience slightly different growth dynamics, similar dynamics were assumed taking into account the canalization dynamics of the field-layer vegetation This assumption is in line with experimental measurements, which show that the soil loss in harvested coniferous forests dramatically decreases starting from the third year following the cut .Between the fifth to the tenth year after the wood harvesting, the C-factor decreases from 0.009 (corresponding to forest cover of ca. 20% or range lands 60%) to 0.003 (corresponding to forest cover of ca. 40%, range lands 95%). With respect to forest fires, the percentage of soil exposed to erosion and the vegetation recovery after the fire are closely related to the severity of the fire In literature, the post fire forest C-factors applied ranges from ca. 0.02 (low severity) to 0.3 (high severity), with a mean
