Resumen

During the last 40 years land management of the central Spanish Pyrenees has changed much. For centuries, sunny, steep slopes were cultivated with cereals. At present, most of the hillslopes have been abandoned and the old fields are colonized by different shrubs or have been reforested with pines. These changes result in a decrease in runoff and sediment yield. At a basin scale changes in the location and extent of sediment sources have been detected, and as a consequence of these changes channels have partially stabilized their sedimentary structures.
