RESPUESTA EROSIVA DE UN SUELO FORESTAL MEDITERRÁNEO TRAS EL IMPACTO DE UN FUEGO RECURRENTE (original) (raw)

In this work, the effect of the water erosion processes on a Mediterranean forest soil (Rendzic leptosol) affected by a repeated fire, after eight years of recovering from previous fires of moderate and high intensities occurred in 1995, has been studied. The research was developed in a Permanent Experimental Field Station of La Concordia (Valencia, Spain), during the period 2002-2004, one year before and one year after the repeated fire. Until the incidence of fire in 2003, the evolution during eight years of soil and vegetation characteristics has favoured the decrease of the differences on runoff generation between fire treatments, which were stressed after the 1995 fire. However, differences in runoff yield between burned and unburned plots (remaining the natural occurring vegetation) remain important (72%). Immediately after the repeated, which was of moderate-low intensity, differences between burned and control treatments increased a 20% respect to values previous the fire. T...
