2.2.1.1. Grossseggenried

Magnocaricion

Description

Phyonomy and Ecology (© Delarze & al. 2015)

Die Vegetation dieses Lebensraumtyps wird durch vorwiegend grosswüchsige Seggenarten (60 bis 150 cm hoch) dominiert. Dazu gehören auch Arten, die höckerartige «Bulten» bilden (Carex appropinquata, C. elata, C. paniculata). In der Zonation natürlicher Ufer schliesst diese Vegetation landwärts an das Wasserröhricht (2.1.2.1) an. Sie übersteht mehrwöchige Überflutungsperioden, im Winter sogar mehrmonatige, und Wasserstandsschwankungen um 60 cm. Der Boden bleibt dauerhaft feucht und ist neutral bis leicht basisch. Er ist häufig sauerstoffarm und schlecht belüftet. Der Nährstoffgehalt ist unterschiedlich und lässt sich an den vorhandenen Zeigerarten ablesen.

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.
