Description Study is devoted to vicinism on non-forest calcareous spring fens and their contact communities on the western margin on the Western Carpathians. The bedrock is variable in its chemistry with calcium-rich flysch beds in the south. There is an climatic gradient from south-west to north-east. The fen vegetation in the north-eastern part of the study area harboured more species typical of contact communities and displayed higher similarity with contact vegetation than the vegetation of mostly tufa-forming fens in the south-west. Species richness of fens correlated significantly with neighbouring species richness in the north-eastern part of the study area, whereas no correlation was found in the south-western part. There is also a large contrast in moisture conditions between fens and neighbouring vegetation in the SW regions. Species from extremely species-rich contact communities cannot grow in tufa-forming fens. The results have demonstrated that vicinism not always plays a significant role.
