Project summary

Edit project overview to modify the project summary.


This project is part of the National Strategy for River Restoration (an initiative of the Ministry of Environment, developed in the Zújar River by the Confederación Hidrográfica del Guadiana) and the State Special Fund to Revitalize Economy and Jobs (Plan E). The full project covers 30 km of the river, and to facilitate the execution of the works it was divided into four sub-projects. The main objectives of the project were: restoration and conservation of riparian vegetation; restoration of the longitudinal and lateral connectivity of the fluvial ecosystem; preservation of the Public Hydraulic Domain from new pressures; environmental education and awareness through the development of outreach activities; enable wildlife mobility; monitoring the biological and physical factors of the reach. The total budget to carry out the rehabilitation and restoration of 30 Km of the Zújar river was 16.240.282 €. The extent of the project is limited to the Public Hydraulic Domain as the first stage of what could be -thanks to land acquisition- a more ambitious floodplain restoration project.
