2.1.2.2. Flussufer- und Landröhricht

Phalaridion

Description

Phyonomy and Ecology (© Delarze & al. 2015)

Phalaridion entsteht oft an Seeufern im Laufe des Verlandungsprozesses von Wasserröhrichten (2.1.2.1). Je nach Nährstoffgehalt können mesotrophe und eutrophe Varianten unterschieden werden. Diese terrestrischen Röhrichte entwickeln sich bei Seen hinter der Stranddüne auf stark eutrophen Sumpfstellen, aber auch an den Ufern von Fliessgewässern, die beim tieferen Sommer-Mittelwasserstand periodisch trockenfallen. Im ersten Fall dominiert das Schilf (Phragmites australis), im zweiten das Rohrglanzgras (Phalaris arundinacea). Die lokalen Nährstoffanreicherungen durch angespülte Sedimente, Erde und Strandgut begünstigen das Aufkommen nitrophiler Arten (z.B. Urtica dioica, Solanum dulcamara, Calystegia sepium). Dort kann die Krautschicht ausserordentliche Wuchshöhen (4 bis 5 m) und eine ausserordentliche Produktivität (17 t/ha) erreichen. Bei weniger nährstoffreichen Varianten gibt es fliessende Übergänge zu Grossseggenrieden (2.2.1).

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.
