The paper presents results of two-year (2003–2005) monthly studies on terrestrial malacocoenoses in an ash-elm forest (Fraxino-Ulmetum) near Duszniki in western Wielkopolska (W. Poland). Species composition, dominance structure and abundance of malacocoenoses of selected plots were analysed. Twenty species of ten families were recorded, represented by 7,619 specimens. The main components of the malacocoenoses were Nesovitrea hammonis (Ström), Columella edentula (Drap.), Vallonia costata (O. F. Müll.), Punctum pygmaeum (Drap.), Cochlicopa lubricella (Porro) and Vertigo pusilla O. F. Müll. The species composition was stable but the abundance varied considerably.
