| Zusammenfassung |
| Forests and natural shrubland vegetation are commonly thought to offer the best
protection against interrill and rill erosion. Nevertheless, the number of studies
reporting field-measured plot-scale data on annual runoff (Ra), runoff coefficients
(RCa) and soil losses (SLa) is limited compared to other land use types and an
overview of the available data is currently lacking. Therefore this study aims to
assemble and analyse available field-scale Ra, RCa and SLa data for Europe and the
Mediterranean. From an extensive runoff and soil loss plot database, compiled in the
framework of the FP6 project DESIRE (http://www.desire-project.eu), Ra data for 59
plots under forest and 84 plots under shrubland (corresponding to 301 and 372
plot-years of measurements respectively) and SLa data for 59 plots under forest and 113
plots under shrubland (corresponding to 334 and 589 plot-years of measurements,
respectively) are extracted and analysed. Forest plots show a median RCa of 1.6% and a
median SLa of 0.1 Mg.ha-1.yr-1, while in shrubland a median RCa of 1.1% and a
median SLa of 0.1 Mg.ha-1.yr-1 is observed. Significant positive correlations
between RCa and SLa are found for both forest and shrubland (p |
