A hilly area along the Tyrrhenian coast, east of the town of Civitavecchia. Habitats include maquis, broadleaved woodlands of beech Fagus, and extensive wooded pastures. The main land-use is cattle- and horse-rearing.
An important breeding site for many SPECs, especially raptors (the best site in Italy for Circaetus gallicus), owls, larks and shrikes. In the 1970s three pairs of Neophron percnopterus also bred. Species of global conservation concern that do not meet IBA criteria: Falco naumanni (occurs on passage).
Pressure/threats to key biodiversity
