Vegetation of the Czech Republic

Class VD
Littorelletea uniflorae Br.-Bl. et Tüxen ex Westhoff et al. 1946
Vegetation of oligotrophic water bodies

VDA Littorellion uniflorae

VDB Eleocharition acicularis

VDC Sphagno-Utricularion

This class includes macrophyte vegetation of oligotrophic to mesotrophic, in some cases also dystrophic water. It includes two physiognomically distinct vegetation types: stands of perennial amphibious herbs rooted in the bottom of a water body (e.g. Eleocharis. Isoëtes and Littorella), and submerged stands of bladderworts (Utricularia intermedia, U. minor and U. ochroleuca) and mosses. This vegetation can be found in lakes, fishponds, peatland pools and other types of shallow, still water bodies. In Europe it is typical of areas of oceanic climate, but in more continental areas including the Czech Republic it is rarer. It has disappeared from many historical localities due eutrophication.
