The site includes a section of the River Guadiana with patches of alluvial woodland and surrounding dehesas and cereal crops. The main activity is livestock-farming.
This is an important area for species associated with riverine habitats, particularly breeding herons. The IBA holds one of Spain's most important colonies of Bubulcus ibis.
