The Natura 2000 Sites in Ría de Arousa protect one of the largest estuarine and coastal ecosystems in Galicia, Spain, renowned for its rich biodiversity and thriving marine habitats.
Located in the southwestern part of Galicia, Spain, the Ría de Arousa is the largest estuarine system among the Rías Baixas coastal inlets. Designated as Natura 2000 sites, several areas within and surrounding the ría have been protected to conserve its unique natural habitats and the diverse species it supports. This network of sites encompasses coastal wetlands, salt marshes, intertidal mudflats, seagrass beds, and forested areas that represent essential habitats for migratory birds, marine life, and endemic plants. The Ría de Arousa is particularly famous for its extensive shellfish beds, including mussels, oysters, and clams, which are of both ecological and economic importance.
Geographically, the ría itself is a ria formed by a drowned river valley, opening to the Atlantic Ocean and surrounded by scenic small towns and natural beaches. Its waters serve as feeding grounds and breeding sites for numerous bird species such as the Eurasian spoonbill, purple heron, and greater flamingo, highlighting its importance as a Special Protection Area (SPA) for birds under Natura 2000.
The terrestrial and marine environments here also support habitats like Atlantic forests dominated by oaks and pines, intertidal zones rich in invertebrates, and seagrass meadows that contribute to water quality and carbon sequestration. Human visitation focuses on ecotourism, birdwatching, hiking along coastal paths, and sustainable shellfish harvesting. Notable nearby landmarks include the Island of Arousa, with its protected dune systems and charming fishing villages. Visitors are drawn by the tranquility of the natural environments mixed with opportunities to explore cultural and gastronomic traditions linked to the sea.
The area's designation under Natura 2000 ensures that both flora and fauna are managed sustainably, balancing conservation with responsible outdoor recreation opportunities.
