This association of Alnus glutinosa swamp forest is usually characterized by the dominance in the herb layer of Carex acutiformis or Scirpus sylvaticus. It occurs in waterlogged sites, but the water table does not rise above the ground level as often as in the previous two associations of alder carrs. Also the organic sediment is shallower and the ground surface is not so distinctly differentiated into hummocks and hollows as in Carici elongatae-Alnetum glutinosae. In the Czech Republic this association occurs in the Bohemian Massif.
