The classification of the eight sectors of Calvi bay given by the comprehensive
LIMA index corresponds to the attraction represented by these sites for experienced
sports divers with maximal frequentation at the Pointe de La Revellata and Spano,
these same divers, who are used to the Mediterranean coastline, describe sites that
are even more attractive in other zones like the area around the Scandola reserve.
Access to this reserve would probably result in the highest LIMA classification: an
exceptional level of richness of heritage and an exceptional site.
On the rocky substrates (Punta Revellata, Bibliothèque, Pointe St François, Punta
Caldanu, Algago bay and Punta Spano sectors), the biological classification given
by the BD index reflects the diversity of results obtained by the scientists of different
disciplines: ichthyology, algology, zoology (Janssens et al. 1993). On the other hand,
the 2 sectors like STARESO and Calvi beach are sandy and are largely colonized
by seagrasses (P. oceanica, C. nodosa). These seagrasses are, on first appearance
monotonous and not very rich but they are recognized as having a high ecological
and economic importance. The LIMA index does not make it possible to describe
the magniolophyta. In this type of area, indexes such as PREI (Posidonia Rapid Easy
