Conservation Actions [top]

Conservation Actions: This species is assessed as Near Threatened (NT) in the Austrian Red List (Reischütz and Reischütz  2007). The known population requires monitoring to establish the severity of the observed population decline described by Reischütz & Reischütz (2009). If current biotope destruction continues to cause population declines throughout the range then conservation measures may be required in the future.
