Guadalquivir Delta

Doñana National Park, established in 1969, occupies much of the Guadalquivir Delta in Andalusia and is one of Europe's most significant wetland reserves. It was designated a UNESCO World Heritage Site in 1994 and serves as a critical stopover for millions of migratory birds traveling between Europe and Africa along the East Atlantic flyway.

The Guadalquivir Delta marshes host over 300 bird species throughout the year, including Greater flamingos, Spanish imperial eagles, Spoonbills, and hundreds of thousands of wintering waterfowl. Doñana is also one of the last strongholds of the endangered Iberian lynx, which relies on the delta's Mediterranean scrubland habitat.

The Guadalquivir Delta is an alluvial plain in Andalusia, southern Spain, formed where the Guadalquivir River empties into the Gulf of Cádiz near the cities of Seville and Cádiz. The river is one of the longest in Spain, and its lower reaches and estuary have been shaped by centuries of sediment deposition and human modification, including drainage for agriculture.

The Guadalquivir Delta ecosystem is under pressure from agricultural water extraction upstream, which reduces freshwater flow into the marshes, as well as from proposed dredging of the Guadalquivir River to allow larger ships to reach the port of Seville. Climate-driven sea-level rise also threatens the low-lying wetlands, and illegal groundwater pumping has periodically been cited by environmental groups and the European Commission as a violation of EU habitat protections.
