The European program CIGESMED addresses the Good Environmental Status of the coralligenous habitats. Its implementation on the field is firstly attempted by 4 protocols to be applied in France, Greece and Turkey. They have been tested in Marseille's region, since early 2014. These protocols are the following: (i) cartography of chosen coralligenous sites, (ii) spatial variability analysis by means of photo-quadrats and image processing, (iii) population genetics study of two common biobuilding species that may be cryptic (the bryozoan Myriapora truncata, and the rhodophyta Lithophyllum cabiochiae), and (iv) metagenomic approach of benthic species. The ultimate aim of these protocols is to link the results from the population genetics analysis and the spatial variability analysis to the sites' features thanks to the cartography. First results suggest that different clades exist for both complex of the previous species. Cartography forshadows models of repartition for species assemblages; they will then be compared between regions in the second part of the project.
