This study examined the effect of wildfire on the physical degradation of two forest soils in NW Spain and compared this against changes produced by controlled laboratory heating experiments in which unburned soils from neighbouring sites were expose

Wildfires increase plot-scale soil erosion rates across the world. However, very few studies have monitored post-fire erosion losses at the catchment scale, especially in the Mediterranean region. The FIRECNUTS project was originally set out to addre

Soil water repellency is a widespread property of Pinus pinaster forest soils in Galicia (NW Spain) that can be intensified by soil heating during fires. Fire-induced or -enhanced soil water repellency, in combination with reduced vegetation and litt

Soil water repellency (hydrophobicity) is a naturally occurring phenomenon that can be intensified by soil heating during fires. Fire-induced water repellency, together with the loss of plant cover, is reportedly the principal source of increased sur

Between February 1998 and March 1999 physical soil degradation was studied in temperate-humid NW Spain after deforestation and slope modification. Changes in bulk density, total porosity, pore size distribution, aggregate stability and soil mechanica

The purpose of this study was to assess how terracing affected overland\nflow and associated sediment losses, at the micro-plot scale (0.25\nm(2)), in recently burnt stands of the two principal forest types in\nnorth-central Portugal, i.e. mono-speci

The present work aims to assess the effects of wildfires on soil aggregate stability and the role therein of contrasting lithologies as well as of fire-induced changes in organic matter content and soil water repellency. To this end, a pair-wise comp

Knowledge of soil erodibility following wildfire is of crucial importance for prioritisation of post-fire restoration practices for soil erosion mitigation. The present work therefore aims to determine the effect of wildfire on soil erodibility for c
