Structure. The habitat is characterized by the high diversity of rare plant species. Communities, which form this habitat types are usually three-layered: herbs with significant projective cover are prevalent in the first layer (Eriophorum species, grasses);
Carex davalliana predominates in the second one and the moss cover in the third layer.
Ecological characteristic. Habitats are formed on peatbogs and soils with a high content of carbonates. These are mainly meso-or eumesotrophic bogs with considerable underground water-feeding, high ground water level and frequent flow of springs.
Threats: Change of hydrological regime (drainage), lowering of the ground water level following by mineralization of the substrate, afforestation, eutrophication (due to application of fertilizers on adjacent agricultural lands) as well as grazings.
Management. Annual cutting of the grass at the end of summer, cutting of trees (felling, uprooting of trees), barrage of reclamation canals.
