The Valle Cavanata Regional Nature Reserve is under the management of the Authority for Parks and Regional Forests of the Autonomous Region of Friuli Venezia Giulia. The presence of several environments between the sea and the mainland (lagoon, beach, wood, meadow, fishing valley, pond) makes it an ideal place for the permanent habitat of several species of birds, while others spend only the winter here. 260 bird species have been identified. Valle Cavanata Reserve has been declared a wetland of international value by the Ramsar Convention, it is a Site of Community Importance and a Special Protection Area.
