Scientific Name: Alzoniella lunensis
Species Authority: Bodon & Cianfanelli, 2002

Assessment Information [top]

Red List Category & Criteria: Vulnerable D2 ver 3.1
Year Published: 2010

Justification:
The species is considered to be a candidate for Vulnerable D2, given the small restricted range, the number of locations and the potential threats to groundwater in the region, with impact of pollution and over-abstraction.  In Italy it was considered to be Near Threatened, and as such could be listed as this status as well.  In order to follow the precautionary attitude elsewhere, it has been listed as Vulnerable D2, pending further data on distribution in the valley and information of the rate of decline in the habitat, and the potential impact on this species.

Population [top]

Population: This species is restricted to a small area, so population numbers are presumably relatively low.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: This species is present in groundwaters in alluvial sediments.
Systems: Freshwater

Threats [top]

Major Threat(s): The species is threatened by its restricted range (Ruffo and Stoch 2006). Since it inhabits groundwaters, the species could be affected by anthropogenic groundwater abstraction and/or pollution (Manganelli et al. 2000).

Conservation Actions [top]

Conservation Actions: No specific conservation measures are known. It is not known whether the species occurs in any protected areas, although other species of Alzoniella are protected in Toscana. The species was considered to be Near Threatened in Italy. More information on population would be a benefit.
