These wet grasslands, dominated by Juncus inflexus and Mentha longifolia, are found in disturbed places, usually around springs in pasture complexes where vegetation is trampled by grazing animals. Soils are base-rich, usually rather heavy, with a high clay content and in some places also appear as slightly saline. This vegetation is common in the flysch Carpathians, particularly in the areas with calcareous bedrock and base-rich mineral springs. Rare and isolated occurrences are also found in other areas with calcareous bedrock, especially in northern and central Bohemia.
