Assessment Information [top]

Red List Category & Criteria: Least Concern (Regional assessment) ver 3.1
Year Published: 2010
Date Assessed: 2009-11-20
Assessor(s): Seddon, M.B. & Slapnik, R.
Reviewer(s): Fehér, Z., Sket, B., Tomovic, J., Vavrova, L. & George, S.
Justification:
Currently this species is reported from a wide area and is present at suitable sites within this region. Although there are threats to groundwater as sources of water for local villages and towns, and from drought phases in the summer the species is considered Least Concern. However, there is some suggestion that (Bole & Velkovrh, 1986 and unpublished data of Sket, pers. comm, 2010), it may only be known from south-eastern Slovenia and adjacent Croatian area. Survey work is recommended for this species, as a suitable time of the year to establish the full range and threats to the species, as it is possible that if widespread loss or if it is restricted to s smaller part of this range then a higher threat category would be applicable.

This species has also been assessed at the regional level:
EU27 regional assessment: As the data for Slovenia are limited, this species has been assessed as Data Deficient at the level of the 27 member states of the European Union.
