What is "salburua"

Salburua is a wetland habitat on the eastern outskirts of the city of Vitoria-Gasteiz in the Basque Country in Spain. The area, which is part of the city green belt, contains lakes, meadows and oak groves. It was drained in the 19th century to transform the area into farmland. Restoration work started in 1994 and has reversed this situation and now Salburua is a Ramsar Wetland of International Importance. The Salburua marshes are considered to be "the Basque country's most valuable area of wetland", according to a Fedenatur report for the European Commission in 2004.
