Vallacuera ravine. Removal of a dyke.
Key features of the case study
The dike built in the 80’s after the canalization works carried out in Arga River was removed to recover the natural floodplain in one of the tributaries’ confluence: Vallacuera stream.
The main objective of this project is to restore the river Arga natural floodplain by removing the dyke and increasing the fluvial territory.
There are other secondary objectives: to increase the quality of habitat in Community Interest Areas, with special attention to European mink (Mustela lutreola); creating new habitats for otter (Lutra lutra) and European turtle (Emys orbicularis); quality improvement of habitats 92A0 (willow and black poplar plantation) and 92D0 (tamarisk plantation); spatial planning for cattle.
