Description :
This paper describes the changes in soil water repellency and soil hydrological and erosional responses to rainfall at small-plot scale, arising from a prescribed fire immediately following burning and one year later in a Mediterranean heathland in the area of the Strait of Gibraltar. Although wildfires will increase soil erodibility, the trends observed in this study suggest that this increased susceptibility to erosion from rainsplash processes may be limited while an intact ash and charred litter layer is still present on the ground surface.
