prales npr mionší – malakozoologický ráj v beskydech

The results of a more than 50 years lasting malacological survey in the Mionší NNR are published here. The virgin forest of Mionší is one of the most important forest reserves in the Czech Republic and it presents the most preserved nature of the forest mountain habitats in the Beskydy Mts. Altogether, 62 mollusc species have been recorded there and we encountered 58 of them during 1998–2005. The molluscan fauna as a whole is characteristic for its high share of Carpathian species. Some of them reach a western limit of their occurrence there (e.g. Vestia gulo). The presence of virgin forest inhabitants (Macrogastra latestriata, Bulgarica cana, Acicula parcelineata) is of prime importance. Macrogastra latestriata, an index species of climatic Holocene optimum, has its largest population within the Czech Republic here.
