Area: 14,812 ha
Site description (2000 baseline)
A freshwater eutrophic lake, about 10 km west of the town of Perugia. It is the largest lake in central Italy (12,000 ha) and the fourth-largest in the country. There is a belt of reeds Phragmites, of variable width, all around the lakeshore, and submerged beds of waterweed (Potamogeton, Ceratophyllum) offshore. Wet woodlands (Salix, Alnus, Ulmus) and grasslands are also present. Tourism is the main activity; pig-farming and intensive agriculture dominate the surrounding area.
Key biodiversity
An area of international importance for wintering Phalacrocorax carbo and other waterbirds collectively (more than 20,000 occur on a regular basis, mainly Fulica atra) and for the presence of a mixed heronry. Winter count data refer to January 1993, 1994 and 1996. The number of wintering birds has greatly increased (especially Fulica atra) following the declaration of the Regional Park in 1995 and the lowering of water-levels.
