Gándaras de Budiño

Gándaras de Budiño is a large wetland area in Galicia, spread across three municipalities: O Porriño, Salceda de Caselas and Tui. Covering roughly 727 hectares, it has held Special Area of Conservation (ZEC) status within the Natura 2000 network since 2014, after previously being listed as a Site of Community Importance (LIC) starting in 2004. It stands among the most valuable inland wetlands in northwestern Spain.

What kind of landscape does Gándaras de Budiño offer?

The area occupies a flat alluvial basin near the Louro River, a tributary of the Miño. Its proximity to the Atlantic coast and consistently high humidity have allowed a mosaic of peatlands, seasonally flooded meadows and riparian forest to persist here for millennia. This combination of habitats supports a level of biodiversity that is unusual for the region, making Gándaras a rare example of a well-preserved freshwater wetland in this part of Galicia.

Why does this site matter so much for conservation?

The wetland is a stronghold for the European pond turtle (Emys orbicularis), locally known as "sapoconcho", a species under significant pressure across the region. In recent years, Galician authorities launched a habitat restoration program focused on this species, partly financed through the EU's Next Generation recovery funds, with a budget exceeding 800,000 euros. The works aim to restore the wetland's natural hydrology, improve water quality and reduce the impact of invasive species that had degraded parts of the site over past decades.

What historical significance does the area hold?

Gándaras de Budiño is not only a nature reserve — it is also one of the oldest documented sites of human presence anywhere in Galicia. Archaeological research has uncovered evidence of settlement dating back more than 310,000 years, with more recent layers ranging between 25,000 and 55,000 years old. This exceptional continuity of human traces has made the site a point of major interest for researchers studying Iberian prehistory.

How is the site being restored today?

In recent years, the O Porriño local government and the Xunta de Galicia have worked together to recover the wetland's original ecological functions, from regulating water levels to restoring the vegetation typical of peatlands and riparian forests. Investment in infrastructure and monitoring is intended to halt the gradual degradation caused over the years by agricultural and industrial activity in the surrounding area.
