“…Many plant species in fire-prone forests are well adapted to wildfire and can recover quickly following even severe fires (Lyon and Stickney, 1976;Turner et al, 2003;Kim et al, 2008). However, second year live plant cover on our study sites was often much lower than reported after other fires in the Eastern Cascades (Schoennagel and Waller, 1999; Robichaud et al, 2006;Dodson and Peterson, 2009;Peterson et al, 2009) and elsewhere (Robichaud et al, 2000;Kim et al, 2008). We note, however, the strong negative relationship we observed between site elevation and vegetation cover, species richness and tree regeneration, and the fact that the Tripod Wildfire burned a higher proportion of high elevation forests than some other fires in the region.…”

“…Negative ecological effects of straw mulches were pointed out by Kruse et al (2004), such as the reduction of the density of conifer seedlings and the involuntary introduction of non-native seeds. Wood chips were found to have little effect in reducing post-fire soil losses in various studies (Kim et al, 2008;Riechers et al, 2008;Fernández et al, 2011). This could be due to the shape and size of the chips.…”

ABSTRACT. Post-fire soil erosion risk assessment is not exempt of uncertainties. In many parts of the world post-fire soil erosion can have devastating effects over forest ecosystems, infrastructures and human life. However, in the Mediterranean countries, it has been defined as "low" and it was attributed to a long history of intense land use. This review paper integrates the last research assessing post

“…Landslides (Lee, 2004), deforestation (Woo et al, 1995) and forest fires threaten the resource soil in Korea (Kim et al, 2008). Compared to these mentioned processes, sheet (inter-rill) erosion of soils is a gradual process which passes mostly unseen especially on noncultivated sites but may be responsible for high sediment loss.…”

Combined use of stable isotopes and fallout radionuclides as soil erosion indicators in a forested mountain site, South Korea

Abstract. The aim of this study is to assess and to validate the suitability of the stable nitrogen and carbon isotope signature as soil erosion indicators in a mountain forest site in South Korea. Our approach is based on the comparison of the isotope signature of "stable" landscape positions (reference sites), which are neither affected by erosion nor deposition, with eroding sites. For undisturbed soils we expect that the enrichment of δ15N and δ13C with soil depth, due to fractionation during decomposition, goes in parallel with a decrease in nitrogen and carbon content. Soil erosion processes potentially weaken this correlation. The 137Cs method and the Revised Universal Soil Loss Equation (RUSLE) were applied for the soil erosion quantification. Erosion rates obtained with the 137Cs method range from 0.9 t ha−1 yr−1 to 7 t ha−1 yr−1. Considering the steep slopes of up to 40° and the erosive monsoon events (R factor of 6600 MJ mm ha−1 h−1 yr –1), the rates are plausible and within the magnitude of the RUSLE-modeled soil erosion rates, varying from 0.02 t ha−1 yr−1 to 5.1 t ha−1 yr−1. The soil profiles of the reference sites showed significant (p < 0.0001) correlations between nitrogen and carbon content and its corresponding δ15N and δ13C signatures. In contrast, for the eroding sites this relationship was weaker and for the carbon not significant. These results confirm the usefulness of the stable carbon isotope signature as a qualitative indicator for soil disturbance. We could show further that the δ15N isotope signature can be used similarly for uncultivated sites. We thus propose that the stable δ15N and δ13C signature of soil profiles could serve as additional indicators confirming the accurate choice of the reference site in soil erosion studies using the 137Cs method.
