Project summary
The Soto of El Estajado has an area of 64 hectares. The main surface was occupied by old black poplar plantations and little bad conserved areas of Community Interest Areas 92A0 and 92D0. The area was used for inappropriate cattle. The actuation area limits with an important community of European mink (Mustela lutreola). The actuations are aimed at preserving this protected species.
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 92D0 (tamarisk plantation); spatial planning for cattle; restore the natural riparian vegetation in Aragon River.
The project has a total budget of 152.948,34€ and is financed by GERVE-LIFE project, INTERREG GIRE project, "Gestión Ambiental, Viveros y Repoblaciones de Navarra, S.A." and Government of Navarre.
