  • cover, water repellency was highest at sites covered by holm oak litter. At soil surfaces covered by cork oak litter, dry grass and mosses the degree of repellency was lower. Almost all sites with a bare soil surface were hydrophilic. A significant
  • positive relationship between livestock density and the degree of bare soil existed, and consequently, areas with high animal numbers were dominantly hydrophilic. No significant relationships were encountered between the degree of soil water repellency
  • and less concentrated and reduced in variability with depth. A multivariate analysis performed and other results suggest that land mismanagement and excessive stocking rates could be related with the appearance of bare soil areas, therefore negatively
