Conservation and breeding status: LC (EU), LC (IT), LC (MED), B

This palearctic lentic species was recorded and breeding confirmed in EXP (4,6) and PDS (15). Two historic records were reported for the municipality of Craveggia in Vigezzo valley, which lies on the northern slope opposite to the VGNP boundary, by De Carlini (1892) and Bentivoglio (1908a, in Capra & Galletti 1978); this data were cited by Boano et al. (2007), who reported it as widespread in low hilly areas and plains in Piedmont but missing from the rice growing district and localized in alpine valleys. This evaluation was probably influenced by the limited availability of data at the time, as later surveys showed that its distribution includes many alpine valleys in Piedmont, except in the south of the region ( Riservato et al. 2014c). Most breeding populations are reported below 800 m in Switzerland ( Wildermuth et al. 2005) and records are concentrated below 500 m in VCO. Therefore, the breeding population that was observed in PDS at ca 950 m is at a rather high and unusual elevation for the region.
