Key features of the case study

The ecological improvement of the Negro river is part of a national river restoration programme, Estrategia Nacional de Restauración de Ríos, developed by the Ministerio de Ministerio de Medio Ambiente, y Medio Rural y Marino (Ministry of Environment). The Confederación Hidrográfica del Duero is the organism which has implemented this project, as others of the Duero basin.
The principal objective of this initiative is to restore trout populations and the naiad Margaritifera margaritifera, which is in serious danger of extinction.
The main threat to these species is the presence of weirs that make difficult or impossible the migration of the trouts upstream,which are the propagation vector of the naiads, affecting their reproduction.
