Lago de Caicedo-Yuso y Salinas de Añana. 24/10/02; País Vasco; 26 ha; 42°48'N 002°59'W. Two wetlands situated in the geological Cantabrican deep with much salty resurgences. Lake Caicedo-Yuso (13 ha) receives salt groundwater, creating a particular water chemistry and inland saltmarshes Juncetalia maritimi, a natural habitat listed by the EC Directive. The dragonfly population of Coenagrion mercuriale is of international importance. The other wetland consists of the terraced brine panels of Añana (13 ha), located nearby in the geologically peculiar valley. The water terraces have been used since the 9th century, and still are today, to produce salt through solar evaporation, and they harbour an endemic variety of the brine shrimp Artemia parthenogenetica. Ramsar site no. 1258. Most recent RIS information: 2002.
