Structure. The basis of habitats are one-, two-layered communities, 50-150 cm high, mainly composed of characteristic species, in particular
Alopecurus pratensis , which forms up to 90% of cover.
Scirpus sylvaticus and
Carex acutiformis are dominants of minor coenosis in the microrelief depressions, while
Deschampsia caespitosa and
Poa pratensis predominate at the degraded areas.
Ranunculus repens ,
Carex hirta ,
Trifolium repens Photo: Н.Сичак etc. take a considerable part in the formation of a lower sward layer subjected to the pasture load.
Ecological characteristic. Ordinary communities of the floodplain meadows are sporadically distributed on relatively fertile, moderately wet meadow soils, dried up boggy and rarely peat ones. They are mainly concentrated in the central parts of the Western Bug river floodplains and its biggest tributaries.
Threats. Change of hydrological regime of the soil (drainage) and those of management methods, ruderalisation.
Management. Maintenance of the appropriate hydrological regime and cutting terms. Limitation of applying herbicides and fertilizers on adjacent agricultural lands.
