Isola di Ustica

The island of Ustica, in the Tyrrhenian Sea, is a volcanic relic of extensive underwater structures. It covers an area of 8.65 square kilometers, affecting the coastal strip and the ridges of Cresta del Fallo and M. Guardia dei Turchi. The territory consists mainly of Quaternary volcanic rocks. The climate is sub-dry thermomediterranean, with average annual temperatures of 16.6 °C and average precipitation of 363 mm. Being a recent volcanic island, it has a limited presence of endemic species, which are concentrated mainly along the coast. The interior area shows signs of ancient human influence. Ustica is an important migratory route for numerous bird species, with frequent stopovers during both spring and autumn migrations.
