Wild fires in a mountain area cause severe runoff. The runoff causes secondary mal-effects such as soil erosion and environmental contamination. Korea had suffered from serious soil yield problems at Imha reservoir in 2003. The muddy flow in the reservoir lasts for an years at that time and the water resources problem had prevailed around the watershed. But there was no reliable method in predicting the amount of soil yield and developing count measures against soil erosion. The goal of this research is to find the sustainability transition of land cover characteristics in a wild-fired watershed. For the success of this research, experimental watershed which had suffered from wild-fires was operated last five years. With the collected field data, the transition of land cover characteristics of watershed was analyzed. It was found that the land cover factor was increased about one hundred times at first year after the wild fire. Then it decreases constantly until it remains stable condition which is reached at fourth year after wild-fires.

Forestry management is crucial in mitigating erosion processes after extensive fires in Mediterranean woodlands. Fire alters forest ecosystems, causing an increase in rates of geomorphic processes. The September 1989 fire in Mt. Carmel covered an area of 4 km2 in the main recreation area of a typical Mediterranean forest area. Six experimental plots, covering an area of 300-500 m(2) each, were established in order to determine the effect of forestry management practice on soil erosion after the fire; runoff and sediments were collected during and after each rainstorm. Rainfall was measured by two recorders and several rain gauges at the study site. During the first year following the fire, sediment yield was 100-500 times higher than on vegetated slopes. Sediment movement was increased mainly by the lack of vegetation. Results show that there is a clear trend of decrease in sediment yield between the first year and the next five. After this period the burnt areas recovered to similar rates of erosion as in the unburnt areas. The clearings of burnt logs by machine and cable sliding increased the sediment yield in the experimental plots. After vegetation development in the second season following the fire, no significant differences were found among the types of management practice plots.

This study assessed the effectiveness of different methods of reducing soil erosion after a severe wildfire in Galicia (NW Spain). The treatments compared were: straw mulch (2.5 Mg ha–1), wood-chip mulch (4 Mg ha–1), cut-shrub barriers and control. Straw mulch provided an initial ground cover of 80% and the wood chips only 45%. Sediment yields were measured by means of sediment fences in 500-m2 bordered plots. During the first year after wildfire, mean precipitation was 1520 mm. The mean sediment yield in the control plots was 35 Mg ha–1. During this period, only straw mulch application significantly reduced soil erosion relative to controls (66%). The mean sediment yields in the wood-chip mulch and erosion barrier treatments, 33 and 30 Mg ha–1 respectively, were similar to rates in the untreated plots (35 Mg ha–1). Soil erosion decreased sharply during the second year after wildfire when mean precipitation was 1194 mm. Vegetation regrowth was very fast and treatments had no significant effect on the rate of recovery of vegetation cover, which was ~80% at the end of the study. The results obtained showed that ground cover was a key factor in determining post-fire soil loss. Stabilisation treatments such as wood-chip mulch and erosion barriers were not effective in reducing soil loss relative to the untreated control.
