We classified vegetation of wet meadows in the western part of flysch Carpathians in Slovakia. We tried to classify wet meadow communities in the study area with respect to their diversity at a wider geographical range. For this purpose, we used the formal definitions based on combination of the species groups which were extracted from a large national database. This way the classification could be valid not only at a regional scale, but also for the whole territory of Slovakia. We distinguished six associations of the Calthion alliance by combining six species groups and the dominance of some species respectively. The major gradient was associated with soil moisture and pH and the second most important gradient was associated with available nutrients
