Měkkýši Národní přírodní památky Hrabanovská černava (střední Čechy)
Molluscs of the Hrabanovská černava National Nature Monument (Central Bohemia)

Luboš Beran & Jana Škodová

The Hrabanovská černava National Nature Monument is one of the most valuable wetland areas in Central Bohemia. It comprises diverse wetland habitats such as small pools, littorals, fens with Carex vegetation, and Molinia meadows with willows located on calcareous (lacustrine chalk) sediments along with xerotherm lawns and Festuca meadows on the remnants of sand dunes. This study compares all unpublished malacological data with the first general research of this area and accesses a combined species list of malacofauna from all habitats. Recently, there are 40 species of molluscs recorded, including very abundant population of the fen snail Vertigo angustior and unique populations of two endangered freshwater molluscs Planorbis carinatus and Pisidium pseudosphaerium, both having very rare occurrence in the Czech Republic. The presence of sparsely occurred Vallonia enniensis, Vertigo antivertigo and Euconulus praticola is also remarkable. This paper confirms the special quality of the Hrabanovská černava National Nature Monument as precious refuge for wetland molluscs in the Czech Republic.
