    Key features of the case study

    The Soto of Campollano is downstream Carcastillo town. The work area was located on the left Aragon River bank, where the little tributary Abejar ravine flows into the Aragon River.
    The main objective of this project is to increase the quality of habitat in Community Interest Areas, with special attention to European mink (Mustela lutreola).
    There are other secondary objectives: Creating new habitats for otter (Lutra lutra) and turtle (Emys orbicularis); quality improvement of habitats 92A0 (willow and black poplar plantation) and 3150.

    Site description

    The tributary of Aragon is surrounded in its mouth by a river forest of 32.6 Has called Soto de Campollano represented by the habitat 92AO in a good conservation status.
    In the riversides there are areas of grasslands without interest for the European mink (Mustela lutreola).

    Riparian forest before the start of the project

    Measures selection

    High quality habitat for European mink was created through the construction of three small ponds connected through small meandering channels (211 metres total length) strongly vegetated with bioengineering techniques that stabilize riverbanks and offer refuge for minks movements.
    0,3 Ha of river forest has been restored through the plantation of species typical from habitat 92AO, and connection between the created wetland and the natural ravine and the main Aragon river.

    Success criteria

    Ecological response

    Riparian vegetation

    The project includes the creation of some new habitats that affect animals and plants. New bio-engineering techniques are used to develop and help these riparian communities.

    Vegetation in new aquatic habitat one month after the finalization of the project


    The quality of habitat for the European mink (Mustela lutreola) was improved.


    The quality of habitat for otter (Lutra lutra) and European turtle (Emys orbicularis) was improved too at the same time as the European mink.
