question: Are both Doñana National Park and Guadarrama National Park areas of marshes, streams, and sand dunes?
answer: no
context: Title: Doñana National Park
  Passage: Doñana National Park is a natural reserve in Andalusia, southern Spain, in the provinces of Huelva (most of its territory) and Seville.  It covers 543 km² , of which 135 km² are a protected area.  The park is an area of marshes, shallow streams, and sand dunes in Las Marismas, the delta where the Guadalquivir River flows into the Atlantic Ocean.  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.  The eco-system has been under constant threat by the draining of the marshes, the use of river water to boost agricultural production by irrigating land along the coast, water pollution by upriver mining, and the expansion of tourist facilities.  It is named after wife of the seventh Duke of Medina-Sidonia.
  Title: Crescent Lake National Wildlife Refuge
  Passage: Crescent Lake National Wildlife Refuge is located in the U.S. state of Nebraska and includes 45,818 acres (185 km).  The refuge contains the largest protected continuous sand dunes in the U.S.  A dozen small lakes and numerous ponds are fed by underground aquifers in areas where the sand dunes are below the water table.  Some of the dunes are covered in shrubs and grasses, while others are completely bare.  After the end of the Pinedale glaciation, the Holocene glacial retreat exposed the sand dunes that had been deposited in their current location by the vast continental glaciers.  This refuge manages the North Platte National Wildlife Refuge and together they form the Crescent Lake National Wildlife Refuge Complex.
  Title: Mauricio González-Gordon y Díez

His family estate was located in the wetland region called Doñana in southern Spain and was threatened by drainage efforts in the early 1950s.  González-Gordon with the help of researchers and international support managed to preserve the site, while at the same time donating some of his family land to the conservation effort.  Afterward, González-Gordon became one of the founders of the Spanish Ornithological Society in 1954.  His conservation efforts for Doñana culminated in the creation of the Doñana National Park in 1969.  The area was designated a UNESCO World Heritage Site in 1994.
