A complex of wetlands along the west-central coast of Sardinia, surrounding the town of Oristano, and divided into the following main subsites: Mistras, Cabras, Mar'e Pauli, Santa Giusta, S'Ena Arrubia, Pauli Maiori, Pauli Menta, San Giovanni, Marceddì, Corru s'Ittiri, Putzu Idu, Is Benas, Sa Salina Manna and Sale Porcus. These areas include freshwater and brackish lagoons, ponds, large reedbeds (especially at Santa Giusta) and saltpans, as well as sand-dunes, rocky coasts (between Cuccuru Mannu and Su Tingiosu and at Capo Mannu), and adjacent agricultural land. The main activities are fisheries and aquaculture.
Key biodiversity
A very important site for wintering waterbirds (up to 50,000 or more), especially wildfowl and Phoenicopterus ruber, as well as for migrating Aythya nyroca and for several breeding waterbirds. The total number of waterbirds in January 1993 was 35,775, with 58,367 in January 1994. Species of global conservation concern that do not meet IBA criteria: Aythya nyroca (1-3 pairs breed, max. 13 birds in winter), Tetrax tetrax (resident), Larus audouinii (non-breeding visitor).
Pressure/threats to key biodiversity
The main threats are the burning of vegetation, illegal hunting, and water pollution due to untreated urban and industrial sewage. Over-fishing and agricultural intensification in the surrounding areas are important potential threats to the site. Shooting of Phalacrocorax carbo was authorized in 1994, 1995 and 1996 by the regional authority and the Instituto Nazionale Fauna Selvatica, as the birds were thought to be reducing fish populations in the lagoons. A Regional Nature Park has been proposed for the area of Sinis, and a Regional Nature Reserve for Corru s'Ittiri. Sale Porcus is managed by LIPU.
