Species text

Distribution
This species is restricted to coastal regions of south west Britain, apart from records in North Wales from Puffin Island off Anglesey (Davies 1995) and the Great and Little Orme (Gallon 2001b). S. bavarica is widespread in western and central Europe, but not recorded from Ireland and only Sweden in Scandinavia.

Status
There does not appear to be significant decline but very local in distribution.

Threats
There appear to be no major threats except for a limited amount of quarrying of cliff faces.

Management and conservation
Limit potential quarrying of cliffs.
