Abstract Under dry Mediterranean climate, the vegetation recovery of hillslopes with old abandoned unirrigated fields, leads to a landscape in mosaic (i.e. areas with and without vegetation), as consequence of the continuous structural degradation of the soil caused by water erosion and wildfires. To model this relationship, indexes of structural stability in water of a forest soil classified as Rendzic Leptosol have been investigated in representative soil samples of La Concordia (Valencia, Spain) in areas with and without vegetation. In the laboratory, samples were subjected to simulated action of water erosion, sedimentation, wetting-drying processes, and to different heat-induced intensity. For both the soil under plants and the bare soil al
