Assessment Information [top]

Red List Category & Criteria: Vulnerable D2 ver 3.1
Year Published: 2013
Date Assessed: 2011-03-08
Assessor(s): Feher, Z.
Reviewer(s): Neubert, E. & Ward, J.
Justification:

This species occurs within a narrow range with a very restricted area of occupancy of 16 km2. However, there is no reason to suppose that the area of occupancy, extent of occurrence, number of locations, number of sub-populations or the number of mature individuals are declining or extremely fluctuating. Habitat disturbance is also not a very serious problem at present. Therefore, it is assessed as Vulnerable (VU) D2.

History:
2000 Endangered
2000 Vulnerable

Geographic Range [top]

Range Description: This species is endemic to a narrow area in the south-western Alps in Italy (Prealpi Lombarde, Monte Presolana near Bergamo). In this mountain there might be some local sub-populations, but they probably form one large meta-population. There is material with the following data in the collection of the Hungarian Natural History Museum (HNHM) and in the private collections of Willy de Mattia and Enrico Zallot : "Pizzo della Presolana", "Piani di Vione", "Colere", "Mt. Presolana, 2,100 m asl." On the last visit in 2004 there were no signs that the area of occupancy (16 km2), extent of occurrence (40 km2) or the number of locations are declining or extremely fluctuating (Willy de Mattia, pers. comm).

Population [top]

Population: Although it lives within a restricted range the sub-populations surveyed seemed to be stable at the time of the last visit in 2004 (Willy de Mattia, pers comm).
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology:

This is an obligate rock-dwelling species associated with limestone areas. It is usually found on the bare rock surface, in crevices or at the base of rocks.

Systems: Terrestrial

Use and Trade [top]

Use and Trade: This species is not used.

Threats [top]

Major Threat(s):

Due to its habitat preference, this species is not very sensitive to ecosystem modification or any other realistic threats. But it occurs within a narrow range which is a popular target for recreational activities such as mountaineering, trekking and rock-climbing so it might be affected by disturbance. In the latest assessment (2000), shell collecting was mentioned as a potential threatening factor, but as a locally abundant rock-dwelling species it can hardly be affected by shell collectors.

Conservation Actions [top]

Conservation Actions: This species is listed in the Italian Red List, but its range is thought to be outside of protected areas (www.parks.it). Being a narrow range species, habitat and population trends should be monitored regularly.
