Context

Many shallow coastal areas along Mediterranean coastlines have suffered significant damage in recent decades. Natural habitats have been destroyed by construction and development. Whether the pollution is mechanical or chemical, it has considerably reduced the surface area of healthy shallow seabeds. These habitats are essential for renewing fish populations because they serve as nurseries for most species.

Programme

Shallow coastal waters in the Mediterranean have been a research topic for the Institute for several years, focusing on the Brusc lagoon and Les Embiez islands in general. The LANDEAU programme highlighted the lagoon’s role as a fish nursery and potential ways to restore habitats there. Two other programmes at the same site, SALINE and SALINE 2, were able to refine methods for bringing a degraded coastal environment back to life. Because of its heritage value and multiple environmental roles, the Brusc lagoon was naturally chosen as one of the test sites for a comprehensive study on environmental restoration. In accordance with the Marine Strategy Framework Directive 2008/56/CE (MSFD), the goal of these test sites is to develop innovative procedures that can later be transposed to other sites.

The SAR-LAB programme (Site Atelier de Restauration écologique de la LAgune du Brusc) is a comprehensive environmental restoration experiment, testing various solutions such as:

– artificial structures in ports and lagoons for better ecological functions like nurseries, by making up for the absence of natural habitat and offering more capacity for fish;

– transplanting Cymodocea nodosa (an underwater flowering plant) to restore seagrass meadows;

– restoring a degraded wetland on Les Embiez island;

– using innovative techniques for research and knowledge acquisition.

This is a five-year research project.

Phase 1

MAPPING AND KNOWLEDGE ACQUISITION

This phase involves obtaining the necessary permits, mapping the condition of the lagoon at the outset and identifying equipment and structures for restoring port areas, rehabilitating sites once used to farm shellfish and restoring seagrass meadows using transplants.

Phase 2

MONITORING

Once the various devices have been installed, this phase will involve environmental monitoring, research and development, as well as the operational phase of restoring the wetland.
