This species is largely restricted to mainland Italy and the island of Sicily (Italy); smaller populations are present on the edge of its range in southern Switzerland and western Slovenia (a single site on the Italian border). The species has an altitudinal range of sea level to at least 1,855m asl.
Habitat and Ecology
It is usually associated with lowland woodland and forest; also found in some wetland habitats (e.g. reedbeds). It breeds in standing waters (lakes, small stagnant ponds, water tanks). The species is sometimes found in modified habitats (e.g. rice fields).
It is still quite abundant in Italy, although populations have declined in some alpine valleys.
The species is potentially threatened by local habitat loss to urbanization and water pollution (presumably by agrochemicals). But overall, it is not seriously threatened.
It is listed on Appendix III of the Bern Convention and is protected by national legislation in Italy and Switzerland. It is present in a number of protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
