Doñana National Park (Wikipedia)

"Doñana National Park is located in Andalusia, in the province of Huelva, and covers 543 km², of which 135 km² are a protected area. The park is an area of marsh, shallow streams, and sand dunes inLas Marismas, the Guadalquivir River Delta region where it flows into the Atlantic Ocean. The original area was established in 1963 when the World Wildlife Fund joined with the Spanish government and purchased a section of marshes to protect it. There has been a constant threat to the eco-system, that of drainage of the marshes, the use of river water to boost agricultural production by irrigating land along the coast, and the expansion of tourist facilities.^[2]

The park has a biodiversity that is unique in Europe, although there are some similarities to the Camargue, with which Doñana is twinned. ^[3] Doñana contains a great variety of ecosystems and shelters wildlife including thousands of European and African migratory birds, fallow deer, Spanish red deer, wild boar, European badger, Egyptian mongoose, and endangered species such asthe Spanish Imperial Eagle andIberian Lynx."
