Malakofauna Přírodní rezervace Údolí Teplé (západní Čechy) Mollusc assemblage of the Údolí Teplé Nature Reserve (Czech Republic: West Bohemia)
Libor Dvořák
Author has found 49 mollusc species in the Údolí Teplé Nature Reserve in 2007. The most species occur in alder forest near the Teplá River and in small parts of the talus slope covered by mountain ash, willow, and hazel. The richest sites host up to 30 mollusc species. Perpolita petronella (L. Pfeiffer, 1853) is endangered species of the highest conservation importance in the reserve. Other species interesting in term of regional snail fauna are Euconulus praticola (Reinhardt, 1883) (rare species of wetlands), Semilimax kotulae (Westerlund, 1883), and Discus ruderatus (A. Férussac, 1821) (both boreoalpine species of mountain forests). The mollusc assemblages consist of forest species (ca. 1⁄2), wetland and aquatic species (ca. 1⁄4), and mesophilous species (ca. 1⁄4). Although some open sites are presented in the reserve (along the railway), no xerophilous species or species of open habitats were found. No specific management is necessary to preservation of relatively rich mollusc assemblages.
