Vegetation of the Czech Republic
Magno-Charetum hispidae Corillion 1957
This vegetation type, dominated by Chara hispida, occurs in small unmanaged or less intensively managed fishponds and flooded sand or loam pits. It has also been documented from a natural habitat of pools within a calcareous fen complex near Lysá nad Labem. It grows in water with a higher concentration of calcium than typical of other stonewort associations. This association has been so far recorded at a few sites in warm lowlands of northern and central Bohemia.
