Monte Argentario, Isolotto di Porto Ercole e Argentarola

The site is primarily of calcareous nature and it is connected to the mainland through the tombolos of Giannella and Feniglia. It is an area of great landscape value and it is extensively utilized for tourism purposes. It exhibits karst phenomena and a notable floral diversity, including rare, endemic, and relict species. Thermophilic and xerophilic Mediterranean vegetation predominates on the southwest slope, while on the northeast slopes it is more mesophilic. The area is of significant importance for the conservation of avifauna in garigues and rocky environments, both for nesting and wintering.
