Ustica Island (ITA020010)

Site type: SAC - Special Conservation Area / SPA - Special Protection Area

Code: ITA020010 - Hectares: 349


The island of Ustica is located in the Tyrrhenian Sea, off the coast of Palermo, where it represents the emerged wreck of a vast building of submarine volcanoes, aligned along a fault with an east-west direction and located at a depth of over 1000 m. The island extends for 8,65 sq km, within which the site occupies an area of ​​332,13 m, affecting almost the entire coastal strip, beyond the ridge of Cresta del Fallo (234 m) and M.Guardia dei Turchi ( m 238). From the lithological point of view, the territory is made up of volcanic rocks (mostly of sub-marine genesis) to be traced back to the Quaternary, with the exception of small sedimentary layers of shallow sea emerging discontinuously along the coast. From the bioclimatic point of view, the island is predominantly part of the lower dry thermo-Mediterranean area, with average annual temperatures of 16,6 ° C and average rainfall of 363 mm

Being a recently formed volcanic island, Ustica is poor in endemic species, mainly concentrated along the coast. The internal area suffers from problems linked to the ancient anthropization that has upset over time the physiognomic and structural characteristics of the vegetation cover. The biotope is found along the main migratory route of numerous bird species, some of which are accidental in the Mediterranean. The island of Ustica is of particular ornithological importance as a resting place for numerous birds in spring and especially autumn migration


It falls within the Ustica Island Reserve
