If the fauna is particularly discreet in this landscape, you will notice that this is definitely not the case for the flora, even though we are quick to associate the Calanques with aridity. Approximately nine hundred different species have been inventoried here, or 1/5 of all the species known in France. Among them are the 'survivors of the ice ages', such as the lentsique, a species of evergreen, and some twenty protected species.
Restrained by the elements (dryness, spindrift, wind and salinity), the species that grow in the Calanques do not spread out into large expanses but instead just pop up here and there in relatively small clusters. The land is mostly covered by the plants of the scrubland: the kermes oak, thyme, heather, rosemary and a few pine woods where the Aleppo Pine grows. It is difficult to imagine that the Calanques were once covered by a forest of holm oaks where filarias, terebinths, mastics and other wild olive trees grew, and which was ravaged by fires in 1971, 1979, 1990 and 1994 (often cases of arson).
However, you can still see a few relics of times past at the base of the small valleys where the soil accumulates.
At the edge of the sea, it is the so-called halophile plants (which can live in high salt concentrations and are resistant to spindrift) that decorate the landscape, such as the 'rock samphire' and the 'saladelle'. As for the screes in the rock, they conceal an endemic, rare, and protected species that can only be found between Marseille and Toulon: the 'sabline de Provence' or 'Herbe à Gouffé'.
