This poor-fen association includes vegetation dominated by short sedges (e.g. Carex echinata and C. nigra), rushes and Sphagnum recurvum s. l. Grasses and broad-leaved herbs typical of managed wet grasslands are also common. This vegetation occurs in bog laggs, poor-fen margins and managed fen grasslands with a shallow peat layer. Calcium concentration is usually very low, but it may be higher if phosphorus, nitrogen or iron concentrations are enhanced. In the Czech Republic, this association is particularly common in the Moravskoslezské Beskydy Mountains, where it is the most common association of the class. However, it also occurs in other non-calcareous regions of the country.
