Description
Phyonomy and Ecology (© Delarze & al. 2015)
Zu den Schwimmblattgesellschaften gehört die Vegetation der seichten (1–2 m, selten bis 3,5 m tiefen) Zonen von Stillgewässern, in denen Seerosen und andere Arten von Schwimmblattpflanzen dominieren. Für die meisten Varianten muss der Wasserspiegel relativ konstant sein. Unter optimalen Bedingungen bildet dieser Vegetationstyp in stehenden Gewässern einen ufernahen Gürtel zwischen dem Röhricht (2.1.2.1) und den Laichkrautfluren (1.1.2). Der Grund ist schlickig und eher sauerstoffarm. Das ökologische Optimum liegt in den kalkhaltigen, meso- bis eutrophen Gewässern der tieferen Lagen.
Distribution map
- Calculation method
Current distribution: Weighted sum (number of characteristic and frequent species) per hectare based on current observations. Reported characteristic species are given a weighting of 10, while others are counted without weighting. The habitat is considered to be present in a grid cell (5 x 5 km) if it contains at least one hectare with a minimum value of 11 points.
Potential distribution: Weighted sum (number of characteristic and frequent species) per hectare based on species distribution models. The calculation strategy is the same as for current distribution, but maps derived from species distribution models are used instead of current observations.
