The WWF oasis of Scivu is an enchanting natural beauty area that is 600kms wide in the territory of Arbus. It consists of a coastal line that includes the dunes of Piscinas and Scivu beach: in a Saharan landscape the beach with the sand  alternate rocky cliffs, touched by the west wind.

In the territory there are two Sic Areas ( Site of Community Importance): Capo Pecora - Rio Piscinas-Rio Scivu) and the Geological Mining Park of Sardinia.

The vegetation is the typical Mediterranean scrub (junipers, wild olive, holm-oaks, Spanish broom, myrth rosemary, sea lily, orchids). The Oasis also includes a 150 hectares wood of holm-oaks.

Among the fauna, it is possible to watch the Sardinian deer on the dunes. Among many species of bird there are bee-eaters, Mediterranean passerines, kestrels, peregrine falcons and buzzards.

Some nest of sea turtles (Caretta Caretta) and of Hermann (Testudo Hermanni) have also been found.

In the Oasis it is possible to practice trekking and excursions.
