Valle Bertuzzi and Goro lagoon

Site description (2000 baseline):

Site location and context
This area lies on the eastern Adriatic coast, and comprises Valle Bertuzzi (a large brackish lagoon) and Sacca di Goro (an open lagoon), as well as some smaller sites: Lago delle Nazioni, Taglio della Falce, Scannone di Volano and Valli Cannaviè e Porticino. The main activities are fishing and fish-farming.

Key biodiversity
An important breeding and wintering site for waterbirds, notably for colony-breeding gulls and terns, for breeding Ardea purpurea (the largest colony in Italy and one of the largest in the western Paleartic), and for roosting Phalacrocorax carbo in winter (Valle Bertuzzi is the largest such roost on the Adriatic coast). Winter data refer to January 1994 count only. Wintering waders occur on the sandbanks and beaches of Sacca di Goro.

Pressure/threats to key biodiversity
Important threats to the waterbird colonies are: erosion and subsidence of the islets; predation by rats Rattus; predation, disturbance and competition for breeding sites by Larus cachinnans; disturbance by aquaculture workers. Some or all of the site is covered by a management plan. There have been studies on the colony-breeding waterbirds (since the 1970s), on the impact of Phalacrocorax carbo on fish-farming, and on plants and invertebrates.
