Drosero anglicae-Rhynchosporetum albae

This association includes disturbance-tolerant vegetation of moderately-rich fens with low primary productivity, dominated by Rhynchospora alba and species of Sphagnum sect. Subsecunda, and containing suboceanic species. It differs from the association Campylio stellati-Trichophoretum alpini in the absence of calcicolous species, and from the association Sphagno recurvi-Caricetum rostratae in the absence of Sphagnum sect. Cuspidata as a dominant species group. This vegetation occurs in fens on fishpond and lake margins and on water-saturated sandy soils. The peat layer is shallow, with a large proportion of mineral soil fraction. Concentrations of nitrogen, phosphorus, potassium and calcium are low. This association is most common in the Třeboň Basin, and further it occurs rarely in the vicinity of the towns of Jindřichův Hradec and Doksy.
