The distribution and habitat preferences of the Roman snail (Helix pomatia L.) were studied in the region of Matopolska in 1997-1999. Cluster analysis was used to determine a relationship between the occurrence of snails and different habitat parameters such as habitat type, its naturalness, humidity, plant cover and soil type as well as landscape patchiness. It has been found that the species occurred most abundantly in anthropogenic habitats situated in areas of high landscape patchiness. Morphometric measurements have shown that individuals from sub-urban areas are smaller and that there is certain relationship between the shape of the shell and habitat humidity. They have also indicated a need to verify a size limit for snails collected for economic purposes. The results obtained will be used as a basis for the regional strategy of the Roman snail population management.
