|Scientific Name:||Orcula schmidtii (Küster, 1843)|
|Taxonomic Notes:||According to Fauna Europaea and Hausdorf (1987) this species is comprised of two distinct subspecies: Orcula schmidtii schmidtii and O. schmidtii transversalis Westerlund, 1894.
|Red List Category & Criteria:||Least Concern (Regional assessment) ver 3.1|
|Reviewer(s):||Neubert, E. & Ward, J.|
This species lives within a relatively wide range and there are at least 20 known subpopulations. Total destruction of the preferred habitat across the whole range is not very likely and local activities do not affect the whole species significantly. There is no reason to suppose that the extent of occurrence (EOO), area of occupancy (AOO), 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:
|Range Description:||This species is distributed from Montenegro to nothwestern Greece. The type locality of the nominate subspecies is in Montenegro, near Cetinje. The type locality of O. schmidtii transversalis is Tsumerka [=Athamon Mts.]. Other published locations are: Anilion near Metsovon, Milea near Metsovon (Hausdorf 1987), Loutra near Amarandos (Reischütz and Sattmann 1990), five locations in North Albania (Dhora and Welter-Schultes 1996), Galicica Mountains, 1800 m (Gittenberger (1978). In the Mollusc collection of the HNHM there are a further 12 unpublished locations from Albania, but it might underestimates the real number of subpopulations.|
In Albania it is not rare and therefore there is no reason to suppose that the extent of occurrence (EOO), area of occupancy (AOO) or the number of locations are declining or extremely fluctuating.

Within its relatively large range, this species does not seem to be rare, therefore there is no reason to suppose that number of subpopulations or the number of mature individuals are declining or extremely fluctuating.
|Current Population Trend:||Stable|
|Habitat and Ecology:|
This is neither an obligate rock-dweller nor a silvicol species, but generally associated with limestone areas where it lives in rocky forests or rocky shrublands. It is usually found in the crevices or at the base of rocks in shady and cooler sites, or under stones.
|Continuing decline in area, extent and/or quality of habitat:||No|
This species might be threatened by serious ecosystem modifications (which affect either the rocks or the vegetation in their habitats) such as through forestry, recreational activities and quarrying. However, total destruction of the preferred habitat across the whole range is not very likely, therefore local activities do not affect the whole species significantly.
The species is not protected at the national level in the countries where it occurs, however at least some of the known locations are within protected areas such as in the Park Kombetar Theth in Albania. Due to the distribution of this species and the stable population there are no conservation actions required at present.
