Two white Storks (Ciconia ciconia) nesting on palms, Coto Doñana National Park, Spain

The Coto Doñana National Park, in Spain, was established as a nature reserve in 1969 when WWF joined with the Spanish government and purchased a section of marshes to protect it. Tourism at that time and the spread of hotels along the beach had been a major threat, but is today well regulated, educated and supportive to the management of the park.
