Lagunas de Villafáfila. 05/12/89; Castilla-León; 2,714 ha; 41º4947N 005º3600W. Catalogued Wetland, Regional Hunting Reserve, Nature Reserve, Natura 2000 (SPA, SCI). A complex of saline lakes subject to marked seasonal variations inside a closed drainage basin in a rolling steppe landscape. The lakes have extensive beds of emergent vegetation with fringing saline grassland. Large numbers of ducks and geese (on average 32,000 birds between 1995 and 2010) use the site for wintering, and during the breeding season the site also sustains more than 1% of the Sterna nilotica population. The area holds two important aquifers. The surrounding basin is used in a non-intensive way for cereal crops and grasslands where the threatened Great Bustard Otis tarda can be found. In 2005 a natural resources management plan was developed with conservation objectives and guidelines. Ramsar site no. 451. Most recent RIS information: 2012.
