This project aims to define a typology adapted to the context of Mediterranean lagoons and to establish a first habitat mapping within French Mediterranean lagoons that will take into account their temporal and spatial variability. On the basis of physical, chemical and biological data collected in 36 lagoons since the year 2000, a unique and homogeneous habitat classification has been developed for the first time. It is based on six hierarchical levels : salinity, substrate, light availability, hydrodynamics, trophic status and biology. This habitat mapping (scale 1 :100,000) highlights the mosaic of existing habitats within lagoon ecosystems that have been considered relatively homogeneous until now. The structural definition of these habitats constitutes a first step towards the definition of functional habitats for the organisms living in these lagoons.

The habitat symbology separates the abiotic criteria from the biotic criteria in order to quickly locate the homogeneous sectors from a physico-chemical point of view and the macrophytes. We distinguish :
