The Bay of Audierne, France’s 51st wetland recognized of international value.
In unison with the Departmental Council and the Forum of Atlantic Wetlands, the Pays Bigouden administrations carried out the labialization project by consulting local stakeholders.
The naturalist knowledge collected over the years by organizations such as Bretagne Vivante has made it possible to highlight the value of this site’s biodiversity. Aware of the issues related to the management of this natural space, local authorities have long been working alongside the Conservatoire du Littoral (seaboard preservation trust) and the Finistère Department Council to manage and protect the site.
With 500 hectares of wetlands nested in a vast dune plane bordering the coast, the Bay of Audierne constitutes a unique ecosystem. In the winter when groundwaters overflow and rainwaters pour into the Pays Bigouden, the topography of the site transforms the dune landscapers into a multitude of inland seas, separated from the ocean by a fragile dune cord.
The dune plan also host the Finistères two largest freshwater lagoons Kergalan and Trunvel which combined add up to 1.7 square kilometers.
The diversity of these ecological systems ensures a major biodiversity. The Bay of Audierne has more than 374 species of invertebrates, 1,000 animal species including 300 bird species, among which rare specimens such as the Aquatic Warbler.
As to flora, more than 700 species have been inventoried on the site, 3 of which are classified as of community interest, 26 are protected and 58 considered rare or endangered on a regional or national scale.
