The terrestrial gastropod fauna of the Drawa National Park includes 39 species, of which 29 (74.4%) were present in quantitative samples and subject to quantitative analysis. Dominant species were Aegopinella nitidula (Drap.), Discus rotundatus (O. F. Müll.) and Vitrea crystallina (O. F. Müll.). Snail communities of acid beech forest and a ruderal site with park tree stands in a mixed forest with beech had the highest species diversity index H’, while those of a eutrophic lowland beech forest and acid oak forest showed the highest TDI index of species diversity, and equitability index (J). The mean snail density was 19.3 indiv. m⁻². The presence of Macrogastra ventricosa (Drap.), Laciniaria plicata (Drap.), Bulgarica cana (Held) and Helicigona lapicida (L.) is noteworthy.
