Resumo: 	Coastal Mediterranean lagoons are often defined as homogeneous ecosystems that home many migratory and sedentary species. They also host strong salinity gradients, depth variation and very diverse plant communities, which create small-scale heterogeneity within lagoons. This is why each lagoon must be described as an entity by itself made up of a multitude of homogeneous features, called habitats, which support specific ecological functions for organisms (nursery, feeding, protection against predators...). Although many studies have resulted in collecting high numbers of physical, chemical and biological data in coastal Mediterranean lagoons, there is currently a lack of knowledge of the spatial distribution of these habitats. In our project, we (1) develop a new habitat classification adapted to coastal Mediterranean lagoons and in coherence with EUNIS system (European Nature Information System), (2) map those habitats in French coastal Mediterranean lagoons, and (3) identify and estimate their surface. Based on physical, chemical and biological data collected from 36 permanent French Mediterranean lagoons since the 2000s, we elaborate for the first time a unique and homogeneous habitat classification based on six hierarchical levels: salinity, substrate, light availability, hydrodynamics, trophic state and biology. A total of 224 habitats were mapped in all French coastal Mediterranean lagoons, including 1 to 24 different habitats per lagoon. This habitat mapping (1:100,000 scale) highlights the mosaic of habitats hosted by French coastal Mediterranean lagoons considered until now as relatively homogeneous. The integration of this new knowledge now makes it possible to have tools to help define spatial sampling strategies, management and planning at local and regional scales. The structural definition of these habitats should be a first step towards defining functional habitats for the organisms inhabiting these lagoons.
