Vertigo angustior JEFFREYS 1830 ( Tab. 3)

Currently there is a lack of information about the population size and abundance of this species in Slovakia. Despite the fact, the criterion C1 was evaluated as "good" because of the relatively widespread distribution of the species in Slovakia. Even though a low weight (2 or 1) was appointed for the criterion C1. The criterion C2 (Habitats) was evaluated as "good" from the habitat status point of view and "average" concerning the water regime because of the long-term decreasing of numbers of suitable wetland habitats within Slovakia, generally.

V. angustior is listed as vulnerable (VU) in the National Red List of Molluscs of Slovakia (ŠTEFFEK & VAVROVÁ 2006), which was prepared in 2006 under the categories and criterion of IUCN, version 3.1 (2001).
