Scientific Name: Codringtonia elisabethae Subai, 2005

Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(i,ii,iv)+2ab(i,ii,iv) ver 3.1
Year Published: 2011
Date Assessed: 2010-09-12
Assessor(s): Triantis, K. & Vardinoyannis, K.
Reviewer(s): Livingstone, S., Livingstone, S. & Neubert, E.
Justification:

This species is endemic to Greece. The species has a restricted extent of occurrence (1,100 km2), along with a severely fragmented population and  a continuous decline in the extent of occurrence, and area of occupancy and the number of locations or subpopulations (inferred by Hadjicharalambous 1996). Also, it seems that there is a continuous decline of the species population (Hadjicharalambous 1996). Codringtonia has a quite unusual life cycle of or land snails of southern Europe, since it reproduces in spring. This uncommon life-history pattern is in disassociation with the prevailing climatic conditions in southern Greece (Hadjicharalambous 1996). This constitutes an important extinction threat, considering the current trends of climatic conditions and the human impact on vegetation cover in the preferred habitats of the Codringtonia species (Giokas et al. 2007). This species is listed as Vulnerable (B1a, B1b (i, ii, iv), B2a, B2b (i, ii, iv).

Population [top]

Population:

The populations of the species, although their size cannot be accurately estimated, appear to be in serious decline (Hadjicharalambous 1996). This species is generally considered as rare.

Current Population Trend:Decreasing
Additional data:
Population severely fragmented:Yes

Habitat and Ecology [top]

Habitat and Ecology:

Codringtonia species are found at various altitudes, living in crevices on rocky terrain within maquis and coniferous (except pines) or mixed (deciduous–coniferous) forests (Hadjicharalambous 1996).

Systems:Terrestrial
Continuing decline in area, extent and/or quality of habitat:Yes

Use and Trade [top]

Use and Trade:

This species is not used or traded.

Threats [top]

Major Threat(s):

Grazing and fire can potentially restrict the populations of the species but currently there is no evidence for any direct threats for the species. Nevertheless, Codringtonia has a quite unusual life cycle of or land snails of southern Europe, since it reproduces in spring. This uncommon life-history pattern is in disassociation with the prevailing climatic conditions in southern Greece (Hadjicharalambous 1996). This constitutes an important extinction threat, considering the current trends of climatic conditions and the human impact on vegetation cover in the preferred habitats of the Codringtonia species (Giokas et al. 2007).

Conservation Actions [top]

Conservation Actions:

This species is listed in the Greek Red Data Book as Vulnerable (Legakis and Maraghou 2009).  Although there are a number of areas included in various protection schemes, in which the species is present, there is no conservation action regarding the species. Research on the threats of this species are recommended.
