Ants are widely found in Mediterranean soils, where they increase water infiltration rates by forming soil macropores during nest construction. In the summer of 2009 rainfall simulations of low frequency–high intensity rainstorms were conducted in an orange orchard in eastern Spain on plots that contained ant nests and adjacent paired-plots without ant nests. Ant nests decreased water losses but soil erosion rates were nearly double in areas with ant activity as compared to soil with no ants. The results indicate that the presence of ants can increase soil erosion when rainfall intensity is greater than the infiltration capacity of the ant macropores
