Resumo

During the traditional land management system intense erosion processes affected the Spanish Pyrenees up to 2200 m a.s.l. The destruction of the upper forest levels and the expansion of the cultivated fields on the sunny, steep slopes greatly increased sediment yield to the river channels. Soil erosion reached its highest values under shifting agriculture, fallow land and, in the shrubland areas, immediately after a wildfire. Both in the subalpine and in the submediterranean areas, deforestation explains not only the main features of the landscape functioning but also the fluvial dynamics. © 1997 Published by Elsevier Science Ltd.
