Salburua

Salburua is a wetland complex on the eastern outskirts of Vitoria-Gasteiz, the capital of the Basque Country in Spain. Covering roughly 216 hectares at an altitude just above 500 metres, it forms part of the city's Green Belt (Anillo Verde) and is made up of a mosaic of lakes, meadows and oak groves. Because of its ecological value, Salburua has been designated a Ramsar Wetland of International Importance, placing it among the most significant wetland sites in Spain.

Where did the wetlands come from?

Before the land was converted to farmland, the area held at least three sizeable lakes: Betoño to the west, Larregana to the north, and Arcaute to the southeast. For generations, local communities valued the marshes for their pastureland, hunting and fishing. During the 19th century, however, the wetlands were drained to make way for agricultural use, and much of their original character was lost for decades.

How was the ecosystem brought back?

Restoration work began in 1994, starting with a halt to the drainage of Lake Betoño. In 1998, a dike was built to close the channel that had been draining the lakes of Larregana and Arcaute, allowing natural water flows to be restored and drainage canals to be filled in. The project is now regarded as one of Europe's most successful examples of landscape revitalisation: land that by the 1990s had shrunk to a small surviving wood and a remnant of marsh near Betoño has since returned to a functioning wetland ecosystem.

What is there to see in Salburua today?

The park's current landscape combines lagoons, wet meadows and oak groves, supporting a rich variety of wildlife. Herds of red deer roam the grounds, while the reedbeds and open water attract numerous waterbirds and other bird species. A 2004 report prepared for the European Commission by the Fedenatur network identified the Salburua marshes as the most valuable wetland area in the Basque Country.

Visits typically start at the Ataria interpretation centre, which serves as the gateway to the site's ecology. It offers interactive exhibits explaining how the wetland ecosystem works, aimed at both adults and children, making Salburua a destination for environmental education as much as for a simple nature walk.

Frequently asked questions

Is Salburua part of the city of Vitoria-Gasteiz? Yes, the wetlands lie on the eastern edge of the city and form part of its Green Belt, a network of green spaces surrounding Vitoria-Gasteiz.

Why did the wetlands need to be restored? In the 19th century the lakes of Betoño, Larregana and Arcaute were drained for agriculture, which stripped the area of its original wetland character for more than a century.

When did the restoration work start? Restoration began in 1994, with a key milestone in 1998 when a dike was built to close the channel draining the Larregana and Arcaute lakes.

Why does Salburua matter today? It is considered one of Spain's and the Basque Country's most valuable wetland areas, protected under the Ramsar Convention, and the Ataria centre helps visitors understand and explore its ecology.
