Was Doñana National Park established as a nature reserve before or after Caldera de Taburiente National Park became a national park, that is which was first to receive its designation?
Doñana National Park:  It was established as a nature reserve in 1969 when the World Wildlife Fund joined with the Spanish government and purchased a section of marshes to protect it. Caldera de Taburiente National Park:  It contains the enormous expanse of the Caldera de Taburiente which dominates the northern part of the island, and was designated as a national park in 1954.
