Habitat improvement in highly hydrologically-regulated river sections
The Management plan for the river basin district of Catalonia stipulates that surface collection points located in some river sections must respect a maintenance flow (or ecological flow) regime. Life Alnus, through the Catalan Water Agency, a partner of the project, is working on reaching an agreement with the company Estabanell Energia to implement ecological flows in two hydroelectric power plants: Mariner (Sant Pau de Seguries) and Gallifa (les Masies de Voltregà). Life Alnus will make an ecological monitoring about the effects of this flow release on aquatic communities and river bank vegetation. We expect the flow release along the river to improve the availability of water during the most critical periods of the year, which will allow for better vegetation conditions for alders and improve how the ecosystem functions.
