Site description

The Ansón river source is located in the Collados del Asón Natural Park. It flows through habitats classified as of Community interest, including caves and rocks, peat bogs, beech and oak forests, Mediterranean holm-oak forests and gallery forests along its banks. These are the habitats of species of great interest such as Pyrenean musk rat, wolf, salmon and European bison. Downstream, where the waters from the river meet the sea, lie the Santoña salt marshes. This site is an important staging post on the migration route for hundreds of species of birds, which congregate there during the winter. Three sites representative of the valuable ecosystems along this river have been proposed for inclusion in the Natura 2000 network.
