Abstract <p>The paper presents a prediction of the spread of nine alien land snail species (Mollusca, Gastropoda, Stylommatophora) in the European part of Russia and adjacent territories. Climate variables, land use type, and extended vegetation index were selected as predictors. The potential spread of each species was modeled. The habitat suitability for different numbers of alien species was identified on the study area. An analysis of the potential overlap of ranges has shown which species can co-colonize new territories for them. In general, the most favorable habitat conditions for the studied species are determined in the Black Sea region, the Azov region, the Caucasus, the Podolsk Upland, and the Middle Danube and Lower Danube lowlands. The association of alien land snail species with anthropogenically changed landscapes has been confirmed.</p>
