| Water Framework Directive implementation is a target for European member states implying a strong effort of analysis, prioritization and restoration. Restoration must recover mainly ecological processes rather than simply appearance, beauty or recreational values. Ecological processes in fluvial systems are driven by hierarchical factors such us climate, geology, flow regime, geomorphology, etc acting at different levels. The first step towards restoration is to recognize and characterize the features that rule the fluvial system, leading to a scientific classification of streams among each watershed and the knowledge of biological communities that should live in each type or river class considered under natural conditions or potential conditions in case of artificial water bodies. In this study we present a fluvial classification of Guadarrama River Basin (Central Spain). This classification is based on González del Tánago & García de Jalón (2004) hierarchical method. Furthermore, each fluvial type can be associated to a riparian forest formation, as a result of several cumulative factors. Natural riparian forests appear now modified by human pressures such us present and ancient grazing, flow regulation or water quality. This method allows us to determine the natural driving forces in riparian ecosystems, as well as the degree of human-induced alteration. This is key knowledge in order to design proper restoration programs, “basin-integrated”, to improve the ecological status of fluvial reaches and riparian ecosystems. | |
