In the territory of the SCI "Giara di Gesturi", there are many wildlife species of international importance that are protected by the EU Habitats (92/43/EEC) and Birds (2009/147/EC) Directives.
There are more than a hundred vertebrate species. Sixteen percent of the bird species are listed in Annex I of the Birds Directive, and, therefore, deserve special conservation attention. Among these, we note the presence of the Accipiter gentilis arrigonii, especially in Quercus ilex and Quercus suber forests and conifer formations; the Western Marsh Harrier, Black-winged Stilt, Northern Harrier, Ruff, European Golden Plover and Wood Sandpiper (Circus aeruginosus, Himantopus himantopus, Circus cyaneus, Philomachus pugnax, Pluvialis apricaria, Tringa glareola). They prefer humid environments, such as paulis. The Peregrine Falcon (Falco peregrinus) likes areas with sparse vegetation near wetlands. The Barbary Partridge (Alectoris barbara) inhabits agricultural lands among Mediterranean maquis, scrublands, and natural and artificial recolonization areas. The White Stork (Ciconia ciconia) stays in lands covered with temporary crops associated with other permanent crops, surrounded by natural grassland and wetlands; the Dartford Warbler and the Marmora's Warbler (Sylvia undata and Sylvia sarda) both prefer to live in the Mediterranean maquis or immersed in the garrigue, but the fist is also an inhabitant of the natural and artificial recolonization areas.
The species of amphibians that have been reported are three, among which deserves special attention the Tyrrhenian painted frog (Discoglossus sardus - Annexes II and IV of the Habitats Directive), seen in particular in agricultural lands, deciduous forests and marshes.
There have been five reptile species documented inside the SCI, which are evenly distributed in the territory, but especially in agricultural areas, scrublands and areas with sparse vegetation. The most relevant is the European leaf-toed gecko (Euleptes europaea), inserted in Annexes II and IV of the Habitats Directive.
Among the invertebrates, there is the Great capricorn beetle (Cerambyx cerdo - Annexes II and IV of the Habitats Directive), which damages the structure of the arboreal elements because of its parasitic behave.
