Key features of the case study
- This project is part of the National Strategy for River Restoration (an initiative of the Ministry of Environment and developed at the Zújar river by the Confederación Hidrográfica del Guadiana) and the State Special Fund for Revitalize Economy and Jobs (Plan E) . The full project covers 30 km of the river, and for facilitating the execution of the works is divided in four sub-projects.[1] [2] [3] [4]
- The project is based on an extense and deep study of the river reach carried out by the Centro de Estudios y Experimentación de Obras Públicas del Ministerio de Fomento (CEDEX)[5] and the Study for the management, restoration and comprehensive use of the resources of the Zújar river and Action Plan done by the Centro de Estudios Socio-económicos de Extremadura (CESEX) for the Comunidad Autónoma de Extremadura.
- The Zújar river is regulated upstream by two dams (La Serena dam and Zújar dam) circumstance that makes imposible to return to the situation prior to this anthropogenic disturbance. The objective of the project is then the rehabilitation or renaturalization of this river reach, as certain pressures cannot be removed.
- The main objectives of the project are:
- Restoration and conservation of the riparian vegetation.
- To consolidate the longitudinal connectivity and the lateral connectivity of the fluvial ecosystem.
- Preserve the Public Hydraulic Domain from new pressures.
- Environmental education and awareness through the development of outreach activities.
- To enable the wildlife mobility.
- Monitoring the biological and physical factors of the reach.
Site description
Measures selection
Attention: The source of the text is the National strategy for River Restoration Bulletin, Sauce nº 1 (November 2009).
As the main objective of the project is the improvement and restoration of the riparian vegetation, there are planned several actions aimed to recover disappeared vegetable communities at certain areas and to enrich and diversify degraded communities.
- Treatments for improve the health status of the existing vegetation, through prunings, removal of of dead trees;clearing brush in areas where riparian habitats are going to be restored and the dominance of brambles means competition for the regeneration of tree specimens. Exotic species, like the eucalyptus, which appears over the whole reach in small stands or isolated, will be removed progressively as it means competition with the rest of riparian species. Clearing will be done in poplars for reducing the density and facilitate the subsequent introduction of native species which increase the diversity.
