Site description Freshwater marshes with alluvial forest and other water-fringe vegetation, located in the centre of the country, c.90 km north-east of Lisbon. The site is drained every year so that the outer areas can be cultivated but the core area is left flooded in most years. This IBA is located very close to the expanding town of Golegã.

Key Biodiversity One of the largest heronries in Iberia, also holding important numbers of breeding Platalea leucorodia, Milvus migrans and Chlidonias hybridus, and nationally important numbers of wintering duck.
