Vertigo moulinsiana (DUPUY 1849) ( Tab. 5)

V. moulinsiana is the species with a relict occurrence in Slovakia as well as V. geyeri mentioned above. Isolated localities particularly in southern and eastern Slovakia are the main distribution areas of the species in Slovakia, as well as suitable localities in Biele Karpaty Mts, Malé Karpaty Mts and Považský Inovec Mts. The species is endangered in Slovakia (ŠTEFFEK & VAVROVÁ 2006) according to categories and criterion of IUCN, version 3.1 (2001).

At present there is a lack of data concerning the species population size and abundance in Slovakia. Despite the low abundance, the population is more or less stable at the localities, which have been irregularly monitored for more than 2 years. The criterion C1 (Population) was evaluated as "average". The habitat status was evaluated as "average" because of the step by step increasing eutrophication. The water regime at the localities is suitable at present, without significant negative changes – it means "good" from the species requirements point of view regarding the habitat quality. There is a long-term negative trend in human activities causing fragmentation of the distribution area of the species and liquidation of its habitats in Slovakia as well. Thus, the criterion C3 (Threats of habitats) was evaluated as "average" concerning favourable conservation status of the species (see table 5).

Conclusion: V. moulinsiana has "average favourable conservation status" in Slovakia.
