Justification: Hauffenia kerschneri is endemic to Austria, where it occurs in a restricted range and is known from only five sites. The population trend is declining and the number of mature individuals species has recently declined. There are current threats posed to this species, and whilst it is protected under Austrian law, it is not known whether it exists within a protected area. It is suggested that monitoring of the habitat of this species is conducted, along with research into the population trend. This species is considered to be Endangered (EN B1ab(iii,v)+2ab(iii,v)).
