Background Sardinia contains a network of lagoons that extend over some 100 km2. Five of these wetland areas are Ramsar sites which between them support an important number of rare or endangered plant and bird species. Plants such as Plagius flosculosus, Stachys glutinosa, A. paleoendemism, Limonium densiflorum, Corsica-Sicily-Algeria and Sardinia subendemism are found in the lagoon area. More than 35 endangered bird species (exceeding 1 000 individuals) use the lagoon habitats and these include Porphyrio porphyrio, Botaurus stellaris, Ixobrychus minutus and Ardea purpurea. Threats to the lagoon habitat have emerged following an increase in tourism activity, construction of new buildings or roads, and use of lagoon water supplies for agriculture. Habitat restoration responses are required to conserve the lagoon species and particularly on the following sites located in Oristano municipality: Putzu Idu, Sal'e Porcus, Cabras, Mistras, Santa Giusta, Pauli Maiori, S'Ena Arrubia, Corru S'Ittiri, Marceddì and S. Giovanni. Objectives The project’s main objective is to establish a network of Natura 2000 sites that incorporates the Oristanese humid areas and covers the following priority for conservation habitats: 1150 Coastal lagoons; 1310 Salicornia and other annuals colonising mud and sand; 1410 Mediterranean salt meadows (Juncetalia maritimi); 1420 Mediterranean and thermo-Atlantic fruticeti halophilous scrubs (Salicornietea fruticosi); and *1510 Mediterranean salt steppes, Limonietalia. A management plan will be prepared and implemented for the SCI/SPA which will include measures to support the conservation status of Emys orbicularis, Sterna albifrons and Sterna hirundo.
