Vertigo geyeri LINDHOLM 1925 (Tab. 4)

V. geyeri is a relict species in Slovakia with occurrence particularly in the northern part of Europe. In Slovakia the localities of the species are situated mainly in the foothills of Tatra Mts and in the Orava and Liptov regions. The species is listed as endangered (EN) in the national red list (ŠTEFFEK & VAVROVÁ 2006).

Because of the relict occurrence of the species in Slovakia, the population was evaluated as "average" from the population size point of view and "unfavourable" regarding the population abundance. The species is more sensitive concerning the habitats in comparison with the other species. Thus, the habitats (both the status and water regime) and its threats are "average" from favourable conservation status point of view.

Conclusion: V. geyeri has "average favourable conservation status" in Slovakia. Table 4: Vertigo geyeri LINDHOLM – the species status final evaluation within Slovakia
