Scientific Name: Platyla curtii (A.J. Wagner, 1912)
Taxonomic Notes:



Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2011
Date Assessed: 2010-06-24
Assessor(s): Fehér, Z.
Reviewer(s): Neubert, E. & Ward, J.
Justification:

This species seems to be endemic to a relatively narrow range between Friuli Alps and the Istrian Peninsula. The number of known locations is over 15 and there is no reason to suppose that the area of occupancy, extent of occurrence, number of locations, number of subpopulations or the number of mature individuals are declining or extremely fluctuating. Therefore, it is assessed as Least Concern (LC).

This species has also been assessed at the regional level as:
EU27 regional assessment: Least Concern (LC) at the level of the 27 member states of the European Union.
European regional assessment: Least Concern (LC).
Mediterranean regional assessment: Least Concern (LC).

Geographic Range [top]

Range Description:This species is distributed in the southeastern Alps (Friuli Alps) and the Istrian Peninsula. Published distribution records for the species are at Sauris di Sopra, Forni Avoltri, Villa Santina, Höhle Fernitic near Trieste, Veliki dol near Trieste, Zagorje near Pivka, Porozina in Cres Island, Ucka gora in Istria, Buzet in Istria, Medveja in Istria, Veprinac in Istria, five km from Veprinac, Gornje Jelenje, Globocec, Pillersberg and Slepajama (Boeters et al. 1989). There are further unpublished records from east of Socerga; Istria and Mirna valley in Slovenia (HNHM Mollusc Collection, unpublished).

Population [top]

Population:

Due to the hidden life of this species, there are no data on population trend, but there is no reason to suppose that the number of subpopulations or the number of mature individuals are declining or extremely fluctuating.

Current Population Trend:Stable
Additional data:
Continuing decline of mature individuals:No
Extreme fluctuations:NoPopulation severely fragmented:No
Continuing decline in subpopulations:No
Extreme fluctuations in subpopulations:NoAll individuals in one subpopulation:No

Habitat and Ecology [top]

Habitat and Ecology:

This species occurs in the subterranean part of rocky habitats with an apparent preference for limestone areas.

 

Systems:Terrestrial
Continuing decline in area, extent and/or quality of habitat:No

Threats [top]

Major Threat(s): This species occurs in the subterranean part of rocky (mostly limestone) habitats. It is a potential threat to this species if the rocks are destroyed by quarrying or by other reasons. However, the total destruction of the whole habitat is not very likely, therefore this threat is mostly hypothetical.

Conservation Actions [top]

Conservation Actions:

The species is not protected at the national level in the countries where it occurs. It is probable that some of the known subpopulations occur within protected areas.

The geographic range of this species is not exactly known and there is hardly any data on its subpopulations. First of all, any research activity should focus on these points. No conservation actions are thought to be necessary at present.
