The Guadiana Valley Ramsar Wetland is a vital transboundary wetland area along the Guadiana River on the Portugal-Spain border, renowned for its rich biodiversity and important habitat for migratory birds and aquatic species.
The Guadiana Valley Ramsar Wetland encompasses a diverse mosaic of aquatic and terrestrial habitats along the Guadiana River, one of the longest rivers on the Iberian Peninsula, flowing through both Portugal and Spain. This internationally recognized wetland site supports important ecosystems including floodplains, marshes, riparian zones, and reservoirs. Its location makes it an essential refuge for numerous species, particularly migratory and resident birds, fish, amphibians, and mammals. The wetland includes various protected areas and nature reserves on both sides of the border, such as the Alqueva Reservoir in Portugal and the Coto de Doñana in Spain’s vicinity. Historically, the landscape has been shaped by human uses like agriculture, traditional fishing, and grazing, which still persist alongside modern conservation efforts. The Guadiana Valley Wetland offers unique recreation opportunities including birdwatching at observation hides, hiking along well-maintained trails, kayaking, and fishing. Scenic viewpoints provide spectacular sights of the wide, slow-moving river and adjacent woods and meadowlands. It plays a critical role in flood regulation, water purification, and sustaining local rural economies dependent on eco-tourism and sustainable natural resource management. Visitors are drawn to the area for its tranquil ambiance, abundant wildlife, and cultural heritage linked to the river’s historical navigation and settlements.
