Much of the Parque Nacional de Doñana is bordered by the separate Parque Natural de Doñana, under less strict protection, which forms a buffer for the national park. The two parques together provide a refuge for 419 bird species and 37 types of mammal, including endangered species such as the Iberian lynx and Spanish imperial eagle (nine breeding pairs). It’s also a crucial habitat for half a million migrating birds.
