White-clawed Crayfish Austropotamobius pallipes, Ecosystems Services, Mapping and Assessment, Department of Culture, Heritage, and the Gaeltacht. Slugs often frequent compost piles and can easily climb over logs and other structures to reach new habitats. It was once thought that Geomalacus maculosus lives only in wild habitats. Climate change will probably affect the Iberian populations more acutely because the climate there is already hot and dry relative to that of Ireland, which is generally cool and damp.  In numerous localities in Spain, very few individuals of the species were observed at any one time. Aside from its status as a protected species and its extremely limited global distribution, one of the most striking traits of this slug species is its spotted patterning, with two seemingly distinct color morphs occurring in different habitat types. Kerry slugs are found in forestry and peatland habitats in Ireland and is Irelandâsonly protected slug species. Slugs do not have a good public profile and most would consider them at best unpleasant and at worst, pests. Only the freshwater habitat of salmon is considered for designation. , It was once thought that Geomalacus maculosus lives only in wild habitats. The habitat of the Kerry Slug in Ireland is woodland and bogs within the sandstone areas of Kerry and west Cork. These lyre-shaped markings become indistinct as the slugs grow larger. The radula, which is located inside the mouth, is a feeding structure that is unique to molluscs. , The Kerry slug mates in head-to-head position with partners' genital openings facing each other. Kerry slug â favourable conservation status but Irish population is important in a global context as the Iberian populations are severely threatened. Habitat loss and loss of some of their favorite foods (lichens and mosses) have been hurting the populations of the unique little slug. The ovotestisâa combination of ovary and testisâis small, compact and darkly pigmented. 1). The Kerry slug or Kerry spotted slug, scientific name Geomalacus maculosus, is a rare species of medium-sized to large air-breathing land slug.It is a terrestrial pulmonate gastropod mollusc in the family Arionidae, the roundback slugs.. An adult Kerry slug generally measures 7â8 cm (2.8â3.2 in) in length and is a dark grey colour with yellowish spots. Where the ribs meet the upper edge, they sometimes form crenulations ( a scalloped effect) and may also produce the same effect on the lower edge of the jaw. The Kerry slug will suffer from âunmitigated noise disturbanceâ and habitat loss in the construction of the 32km South Kerry Greenway, a hearing in Tralee was told today. 1 offspring of three species of arionid slug, resulting in a loss of âspecies-specificâ colour character-istics. Adapting existing legislation. If slugs are your thing, then the Kerry Slug should be looked out for in wet weather. In response to European environmental legislation, Ireland has designated seven SACs with the slug named as a "selection feature": Glengarriff Harbour and Woodland; Caha Mountains; Sheep's Head; Killarney National Park, MacGillycuddy's Reeks and Caragh River Catchment; Lough Yganavan and Lough Nambrackdarrig; Cloonee and Inchiquin Loughs, Uragh Wood and Blackwater River (Kerry). TV. Kerry Slug (Geomalacus maculosus) 1355. The Kerry slug (Geomalacus maculosus) is notable for its distribution, being found only in Kerry and West Cork in Ireland as well as in northern Spain and Portugal. The project also provided information on the movements of slugs in woodland and on boulder fields. Fauna Europaea search: Fauna Europaea GBIF: Global Biodiversity Information Facility Habitats Directive Art. It is absent from limestone areas.  The best predictor of its occurrence is high rainfall and high summer temperatures.
