Cliffs with endemic Mediterranean vegetation: this type of vegetation grows on rocky coasts, where the action of sea salt is its main limiting factor. Given the scarcity of soil, this vegetation does not provide continuous coverage. In the S. Francesco, C. Maestra, C. Spalmatoio and Ischiaiola areas of Giannutri, this habitat is heavily disturbed by the rapid expansion of Carpobrotus spp., which is capable of substituting the original species and changing the habitat completely.
