Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA MOLLUSCA GASTROPODA STYLOMMATOPHORA HELICIDAE

Scientific Name: Helix godetiana
Species Authority: Kobelt, 1878

Assessment Information [top]

Red List Category & Criteria: Endangered B2ab(i,ii,iii,iv,v) ver 3.1
Year Published: 2013
Date Assessed: 2010-09-19
Assessor(s): Triantis, K. & Vardinoyannis, K.
Reviewer(s): Livingstone, S., Livingstone, S. & Neubert, E.
Justification:
This species is endemic to Greece. The expansion of the cultivated areas and fire has played a role in the restriction of the species' populations and their local extirpation. According to Mylonas (1982, 1983), it was intensive grazing, and the subsequent impoverishment of the species' habitats that had the most significant impact of reducing population size. The species is extinct from most of the island previously present (now only known from subfossils) (Mylonas 1982, 1983). Currently, the area of occupancy is about 72 km2 and there is a continuing decline in any the (i) extent of occurrence, (ii) area of occupancy, (iii) the quality of habitat, (iv) number of locations or subpopulations,  and (v) the number of mature individuals. This species is listed as Endangered B2ab(i,ii,iii,iv,v).
History:
1994 Endangered (Groombridge 1994)

Geographic Range [top]

Range Description: The species is endemic to Greece, being distributed in some of the Cyclades Islands (central Aegean), Rhodes and Astypalaia and some very small offshore islets. For most of these islands it is known from sub-fossils (Mylonas 1982, Mylonas 1983, Triantis et al. 2008).

Population [top]

Population: There is an overall declining trend for the species' population. This species is extinct from most of the islands where it was previously present (now only known from sub-fossils) (Mylonas 1982, 1983).
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: The species is ground-dwelling, found in Mediterranean shrublands in limestone areas and sandy beaches, avoiding forests of Quercus and Pinus (Mylonas 1982, 1983).
Systems: Terrestrial

Use and Trade [top]

Use and Trade: As for most of the large snails of the Mediterranean, especially Helix spp., it is highly possible that this species is eaten as part of the local diet. However, there is no specific data on this.

Threats [top]

Major Threat(s): The expansion of the cultivated areas and fire has played a role in the restriction of the species' populations and their local extirpation. Nevertheless, according to Mylonas (1982, 1983), it was intensive grazing, and the subsequent impoverishment of the species habitats that had the most significant impact.

Conservation Actions [top]

Conservation Actions: This species is listed in the Greek Red Data Book as Critically Endangered (Legakis and Maraghou 2009). The protection of its habitat and monitoring of the population is needed.
