  • Effects of forest fires and post-fire land management practice on soil erosion and stream dynamics, Agueda basin, Portugal : Soil and groundwater research report V


The Agueda basin in north-central Portugal is comparatively wet (rainfall 1,600 to 1,800 mm/year) with frequent, relatively large storms in autumn and winter, yet the summer drought is sufficiently long and severe for frequent forest fires. This publication deals with the impacts of forest fires in this Mediterranean environment on soil loss and catchment hydrology for eucalyptus (Eucalyptus globulus) and pine (Pinus pinaster) forest. Soil loss two years after a wildfire in a eucalyptus and pine forest was two orders of magnitude higher than the corresponding mature unburnt forest. Streamflow in burnt catchments two to four years after the fire was significantly higher than in unburnt catchments, the differences for peak flow being a factor of 2-5. The post-fire land management practice of rip-ploughing was found to be more damaging than the fire itself in promoting soil erosion.
