The destruction of Mediterranean and Atlantic ecosystems by fire is in part caused by profound transformations of soil physical, chemical and biological characteristics, in particular the qualitative and quantitative changes in the soils’ most functional soil fraction, i.e. that of organic matter (González-Pérez et al., 2004). These changes may negatively affect soil health and quality, and induce or enhance runoff generation and, thereby, the loss of soil, a non-renewable natural resource (Arias et al., 2005).
