Abstract

The AA. study the evolution of soil water repellency (WR) and aggregate stability (AS)during a 6-year period after a wildfire in Mediterranean calcareous loamy to clayey soils from SW Spain. They have investigated 1) the fire-induced changes on soil WR and AS in the medium term (6-year period after burning) and its distribution within aggregate size fractions, 2) the relations between post-fire AS and WR, and 3) the interactions between AS, WR and different factors (site, time since burning, lithology and vegetation type) in Mediterranean calcareous soils. Five areas burned during the summer 2006 in southern Spain were selected for this study in the provinces of Cádiz and Málaga. It is highlighted that water repellency persisted in finer aggregates (0.25–1 mm) after 6 years, and that aggregate stability was not affected severely by moderate-severity burning. Moreover, high soil resilience to low-moderate fire disturbance was observed
