Project summary

Edit project overview to modify the project summary.

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 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. 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. 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. The project was presented by the “Environmental Management for Reintroduction and Repopulation in Navarre” in cooperation with the Government of Navarre’s Environment, Land and Housing Department. It was part of a LIFE project.
