Abstract
Terrestrial malacocoenoses of two neighboring forest complexes in W. Wielkopolska were sampled
in 2003–2004; their structure and abundance were analysed in selected plots of oak-hornbeam forest of different
protection status and degree of anthropogenic transformations. Twenty species (10 families) represented
by 1,588 specimens were collected. The main components of the malacocoenoses were: Nesovitrea hammonis,
Aegopinella nitidula, Ae. pura, Punctum pygmaeum, Cochlicopa lubricella, Perforatella incarnata and Carychium minimum.
Both species composition and abundance varied greatly between the plots. The gastropods showed no
preference for old oak-hornbeam stands or plots located in nature reserves. This may suggest that even under
strong anthropopressure and in much transformed environments the snails are capable of maintaining a high
diversity
