Ecological characteristic. Habitats are formed on gleyed soils, rich in nutrients, sand, silty and sand-silty ones with a high ground water level. Usually these nitrophylious communities are located in the form of the narrow strips near riverbeds and channels and occupy a small area. Often they are considered as a stage of succession following after the ceasing of cutting Calthion union meadows. Mainly they number a lot of ruderal species.

Threats. Change of hydrological regime, adjustment of river channels, expansion of neophyte species, farming.

Management. Prevention of the habitats integrity destruction, maintanance of the natural flow of the rivers, limiting the expansion of invasive species.
