Notes on distribution of the Carpathian snail Vestia turgida in the Bohemian Forest


The author summarises all known published and unpublished data on Vestia turgida (Rossmässler, 1836) (Gastropoda, Clausiliidae) from the Bohemian Forest, SW Bohemia. The first find of this Carpathian snail was recorded in this region at the end of 19th century. There are more than 20 localities known in the study area at the present, out of which all are situated within a small islet area of ca. 14×7 km2. V. turgida inhabits mixed forest stands covered by white butter bur. Major part of its localities is concentrated in the Stožec Mt. and Boubín Mt. massives and their vicinities. Many typical mountain forest species live together with V. turgida, namely e.g. Platyla polita (Hartmann, 1840), Clausilia cruciata (Studer, 1820), Discus ruderatus (A. Férussac, 1821), Macrogastra ventricosa (Draparnaud, 1801), Vertigo alpestris Alder, 1838, Semilimax kotulae (Westerlund, 1883), Oxychilus depressus (Sterki, 1880), Deroceras rodnae Grosssu et Lupu, 1965, or Causa holosericea (Studer, 1820). The occurrence of V. turgida is not endangered in the study area because most of its localities are situated in the core zones or Nature Reserves.
