The posidonia oceanica study has been presented in Salina island by Stazione Zoologica Anton Dohrn in collaboration with Blue Marine Foundation and the Aeolian Preservation Fund. The 25% of the seagrass meadows already disappeared because of the effects of climate change and boat moorings. The monitoring is necessary in order to preserve this important ecosystem which constitutes a lung for the sea. The posidonia is a slow-growing plant and can be irreversibly damaged. Please do not anchor on seagrass meadows!
