A new typology of mesic and xeromesic meadow vegetation in the Southern Boreal zone of Karelia is introduced based on the contemporary meadow vegetation conditions and modern multivariate methodological approaches. The main differentiating environmental factors are identified. Currently they include soil nitrogen pool, soil moisture and particle size. Generally, the importance of soil nitrogen is two to three times higher than soil moisture region-wide due to intensive anthropogenic pressure in the second half of the 20th century. Four consolidated associations of meadow vegetation are defined, each characterized by a set of diagnostic species. The shift towards a high soil nitrogen content has been recorded.
