    Key features of the case study

    Attention: The following text is a partial translation of the Project Summary (available in Spanish).

    This project is the result of an initiative from the municipalities of Mañeru and Mendigorría. Gestión Ambiental, Viveros y Repoblaciones de Navarra S.A. in collaboration with Centro de Estudios y Experimentación de Obras Públicas del Ministerio de Fomento(CEDEX) designed the "Environmental Improvement of El Plantío meander".This work was framed within the Interreg IIIa TURN-IMER Comprehensive Management of European Rivers.The Department of Rural Development and Environment of the Navarra Government carried out the execution of the works.

    An old meander has been used during years for agriculture, livestock and forestry, with low economic returns. These drivers changed the structure and composition of the riparian forest, being reduced to small patches or bands along the main channel. The meander and the floodplain around suffered morphological changes as a result of levelling.

    Site description

    The Arga river, tributory of the Aragon river, is one of the main rivers of the Ebro basin. The middle stretch of the Arga river is characterized by a meandering planform, flowing through Oligocene sandstone escarpments, with an annual contribution in natural regime 1450 Hm3 and a catchment area of 2290 km2. The riparian forest is composed by vegetal communities of willow, poplar, elm and tamarisk. The wildlife associated to this habitat has a great value for conservation purposes. Among the diversity of species we can find several mustelids, and species of diurnal and nocturnal birds of prey.

    Monitoring before and after implementation of the project

    Socio-economic aspects

    The project was divided in three stages:

    • Morphological restoration. Realised in 2009 with a budget of 129.916,97 euros in a period of 2 months.
    • Revegetation of the riparian zone and Public Use adaptation. the budget is of 127.495,10 euros and the duration of the works of 5 months.
    • Maintenance and Environmental Monitoring.

    The project emerged from the Town Council of Mendigorria and Mañeru, as an example for spread the benefits of river restoration. the municipalities participated in the design of the project. Also, the Public Participation was taken into account for incorporate technical proposals and suggestions of the diffrent social actors, and find a solution that reach together the objectives of the project and local preferences.
