Meadows take up over 10,3 % of the Reserve's site. There are three natural grassland vegetation complexes, viz. the Berezina river flood-lands, the Serguch river flood-lands and extrainundated grassy mires. Meadows and grassy fens are mainly located in the Berezina flood-lands and total 77,8% of the grasslands. In the Serguch flood-lands they cover 12,1% of the area. Extrainundated herbaceous vegetation is represented by open fens and transitional mires with the total area of 10,1%. In general, 28 grassland-palustrine associations have been identified in grasslands and grassy bogs of the Reserve.
High level meadows are represented by separate hillocks or strings, where Agrostis tenuis, Bromus mollis, Festuca rubra, Hieracium pilosella, Poa angustifolia, Sedum acre, etc. dominate. Sometimes Tragopogon orientalis occur.

Armeria vulgaris, Gentiana pneumonanthe, Gladiolus imbricatus etc. can sometimes be found.
Mean level meadows total 11,7%. Macrogramineous herbage with Deschampsia cespitosa, Festuca pratensis, F. rubra, Phleum pratense, Polygonum bistorta are predominant in them.
Low level meadows total 67,9% of the grasslands and are represented mainly by macrogramineous and macrosedge fens.
