Měkkýši údolí horního a středního Kačáku

A total of 95 species of molluscs were recorded in the Kačák brook valley (Central Bohemia, Czech Republic), in its upper and middle part. Most of the terrestrial survey was conducted in the woody part of the studied area, therefore woodland gastropods represent 31% of the total species number, followed by generalists, hygrophilous and steppe species. Only a few species belong to aquatic molluscs. Twenty four species belong to the Red List of mollusc species in the Czech Republic. Critically endangered Anisus vorticulus, endangered Pisidium amnicum and Unio crassus represent aquatic species. Very attractive are wetlands and marshes in the Kačák brook catchment area, hosting two vulnerable species: Vertigo angustior and V. antivertigo.
