Abstract

Water repellency (WR) is common in the long unburned Mediterranean calcareous soils (> 20 years) studied. This paper : a) reports on the occurrence and persistence of WR in fire-affected calcareous forest soils under Mediterranean climatic conditions, examining its spatial variability at macro-, meso- and micro-scales, and monthly changes with soil moisture content; and b) develops exploratory models to estimate the probability of the natural background (not fire-induced) WR to occur through a Mixed-Effect Logistic Regression Model. Four sites with comparable soil and vegetation types were studied, all of them burned in 1979, the third again 1999, and the fourth in April 2008. Variability of WR was similarly high within site (1 ha) and at 10 × 10 cm plot-scales. It is concluded that the model derived from straightforward variables is powerful in the context applied here
