Vegetation of the Czech Republic

Alliance VBC
Batrachion fluitantis Neuhäusl 1959

The alliance Batrachion fluitantis includes vegetation dominated by different species of Batrachium (Ranunculus subgen. Batrachium), Callitriche, and other submerged aquatic macrophytes adapted to fast running water, usually with fluctuating water table and restricted availability of nutrients. These species have roots or rhizomes firmly anchored in the bottom, elastic and firm stems, and leaves with blades divided into long narrow parts. Some species also have leaves floating on the water surface. Besides generative reproduction, the species often spread through vegetative fragments. This vegetation occurs mainly in the upper and middle sections of rivers or in larger brooks, but also in some clean still water bodies. It is typical of north-western to central Europe, while in south-eastern Europe it is less diverse or absent due to higher temperatures and better nutrient status of streams.
