Assessment Information [top]

Red List Category & Criteria: Least Concern (Regional assessment) ver 3.1
Year Published: 2011
Date Assessed: 2010-07-07
Assessor(s): Fehér, Z.
Reviewer(s): Neubert, E. & Ward, J.
Justification:

Within the range there are only a few known subpopulations, but due to the hidden life of the species, this number is probably underestimated. This species does not seem to be very sensitive to ecosystem modification or other realistic threats. There is no reason to suppose that the area of occupancy (AOO), extent of occurrence (EOO), 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).

Geographic Range [top]

Range Description:This species is distributed in the southeastern Alps. Fauna Europaea indicates that this species is from Italy, Austria, Bosnia-Hercegovina, Serbia, Albania and Romania, but not from Slovenia and Croatia. In contrast, according to AnimalBase, its type locality is in Slovenia, near Moravča ("in voragine "Boltačev brezen" nec non in specu "Ihanška" regions "Moraeutscher Gegend" dictae Carnioliae superioris"). More specific distribution data includes: Eisenerzer Alpen and Karawanken in Austria (Klemm 1973), Valle del Isonzo and Carso in Italy (Alzona 1971). Its occurrence in Albania is doubtful (Fehér and Erőss 2009b) as is its occurrence in the Balkan Peninsula and in Romania. Grossu (1983) indicates that this species is from Romania, but this needs confirmation. There are at least seven definite locations in Austria. If Slovenian and Italian parts of the range are taken into consideration, the real number of locations should be higher and there is no reason to suppose that the area of occupancy (AOO), extent of occurrence (EOO) or the number of locations are declining or extremely fluctuating.

Population [top]

Population:

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 is generally lives in rocky areas, rocky forests or rocky shrublands. It is usually found in the crevices or at the base of rocks in shady and cooler sites, or on the ground among leaf-litter, or decaying dead wood.

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

Threats [top]

Major Threat(s):

This species does not seem to be very sensitive to ecosystem modification or other realistic threats. Local subpopulations might be threatened by the complete or severe destruction of the rocky habitat (quarrying, earthquakes, etc.). Considering the proposed number of existing subpopulations, local activities do not seem to affect the whole population.

Conservation Actions [top]

Conservation Actions:

The species is not protected at a national level in the countries where it occurs. It is probable that some subpopulations live within protected areas such as in the Triglav National Park in Slovenia. No conservation actions are required currently.
