On the French Atlantic coast, human action, by shaping the salt marshes, has contributed to the maintenance of many habitats of Community interest and protected species. This is the case of the Pays-de-la-Loire region, which has nearly 16,000 ha of salt marshes.

This natural heritage is under pressure: lack of hydraulic management, landing, use of mechanical devices during sensitive periods on the one hand, salt and agricultural abandonment on the other hand, invasive species progression, lake of knowledge by the general public …

The LIFE Sallina project (for Sustainable Actions on Loire Lagoons for Improvement and Assessment) aims between 2018 and 2023 to restore and conserve habitats of Community interest and species of salt marshes in the Pays de la Loire region.

From 7 to 9 March 2023, a restitution seminar is organized, during which you are invited
to share knowledge about coastal lagoons, waterbirds in salt marshes, flora and fauna,
wetland management, land management etc.

Organized by the Conservatoire d’espaces naturels des Pays de la Loire, as a part of the LIFE Sallina project, coordinated by Cap Atlantique in partnership with Syndicat mixte de la Baie de Bourgneuf, Syndicat d’aménagement hydraulique Sud-Loire and Communauté de communes de l’Ile de Noirmoutier.
Financed by the European Union, Agence de l’eau Loire-Bretagne, DREAL des Pays de la Loire and Région des Pays de la Loire and all the associated beneficiaries.
