Descripción
The encroachment of riparian vegetation is a widespread phenomenon in most of Mediterranean rivers. The causes of this process have been linked to changes in land use, to reduction of extensive livestock, to a great demand of water for irrigation, and currently, climate change is reinforcing it. These drivers have led to the stabilization of river channels; reducing their dynamism and favoring the growth of woody vegetation in the river banks, and reciprocally, the development of woody vegetation promotes this stabilization. The aim of this work is to assess the riparian vegetation encroachment in Spanish Rivers, frequently associated with changes in catchment land use and flow regulation. To that purpose, we have quantified the vegetation encroachment along the studied period (1956-2014) in some Spanish rivers as a first step to understand its controlling factors, such as: land use, floodplain and channel traits; flow regulation intensity; type of regulation etc. The study was conducted in 14 river reaches, 10 located in regulated rivers downstream large dams and 4 in non-regulated rivers. A diachronic analysis using aerial photographs from 1956 to 2014 was performed to evaluate the morphological evolution and land cover changes in river reaches. Our preliminary results show a generalized natural vegetation encroachment process, together a channel narrowing process.
