Mauricio González-Gordon y Díez, Marquis of Bonanza (18 October 1923 – 27 September 2013) was a Spanish sherry maker and a conservationist.
 Most of his life he worked for the family company, González Byass, where he increased its exports to a worldwide level.
 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.
Forillon National Park, one of 42 national parks and park reserves across Canada, is located at the outer tip of the Gaspé Peninsula of Quebec and covers 244 km2 .
 Created in 1970, Forillon was the first national park in Quebec.
 The park includes forests, sea coast, salt marshes, sand dunes, cliffs, and the Eastern End of the Appalachians.

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.
Sierra de Guadarrama National Park (in Spanish: "Parque Nacional de la Sierra de Guadarrama") is a national park in Spain, covering nearly 34,000 hectares, the fifth largest in Spain's national parks system.

 The park's size is 238 km2 .
 Recreational activities in the park include swimming, cycling and hiking.
 In recent news, the park has reported sightings of the fisher marten in the area, making it one of the few places in New Brunswick that have fisher populations.
 The park's various public activities attract thousands of visitors each year.

Bruneau Dunes State Park is a state park of Idaho, USA, featuring several large sand dunes and two small lakes.
 The park is located south of Mountain Home, Idaho, outside of Bruneau.
 The park is the site of North America's highest single-structured sand dune which is approximately 470 ft high.
 (North America's highest multistructured dune is at Great Sand Dune National Park in Colorado and is approximately 660 ft higher than its immediate base.)
 The park is also the site of the Bruneau Dunes Observatory, where visitors can use a telescope for stargazing.
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.
