- Abstract
In April 2000, a large forest fire burned through the largest mountain range in the eastern coastal area of the Republic of Korea. Although various measures are applied to restore vegetation cover and minimize surface soil erosion after forest fires, few studies have quantified their effectiveness in the Republic of Korea. The goal of this study was to evaluate the effectiveness of rehabilitation treatments on a slowly revegetating hillslope after burning. In 2002, we installed six treatments (ground seeding, hydroseeding, tree planting, sodding, vegetation sacks, log erosion barriers), examined the vegetation coverage and sediment yield in these treated sites, and compared these results to those in an untreated site. The results showed that our study hillslope, which features a high-severity fire regime, erodible silty sands, steep slopes, and frequent high-intensity rainfall, required at least 4 years to achieve surface soil stability through the recovery of native plant species. However, the rehabilitation treatments achieved surface soil stability more quickly. In particular, despite frequent high-intensity rainfall, the hydroseeding and vegetation sack treatments were highly effective in early recovery because they provided seed stability and a high growth rate. The log erosion barrier treatment was critically effective in reducing the sediment yield because it provided storage spaces.
