For the naturalness and the potential for life development of these areas, they are suggested as potential areas meeting the criteria for Ecologically and Biologically Significant Areas (EBSAs). There are also some land habitats recognized as sufficiently valuable to be included in the European Natura 2000 network. The prevailing lithologies are calcareous. Near the rocky shores, especially in shallow bays, there are plenty of seagrass meadows, while deeper subtidal rocky cliffs have peculiar coralligenous habitats.
