2.2.3. Kalkreiches Kleinseggenried (Davallseggenried)

Caricion davallianae

Description

Phyonomy and Ecology (© Delarze & al. 2015)

Diese Flachmoore bilden dichte, niederwüchsige (unter 50 cm) Rasenbestände aus kalkzeigenden Seggen. Oft sind diese Gesellschaften auffallend reich an Orchideen. Die Böden sind basen- und kalkreich. Dabei kann es sich um mineralreiche Rohböden, aber auch um torfige Humusböden handeln. Damit umfasst die Einheit auch die Simsenriede wenig saurer Torfböden (mit Trichophorum caespitosum). Das diesen Flachmooren zufliessende Grundwasser muss gegen Nährstoffe gut abgepuffert sein und enthält oft wenig gelösten Sauerstoff. Die Mehrheit der Gesellschaften erträgt ein periodisches Trockenfallen besser als diejenigen der kalkarmen Kleinseggenriede. Die kalkreichen Kleinseggenriede steigen in den Kalkalpen bis gegen 2100 m hinauf, sie finden sich aber, anders als die kalkarmen Kleinseggenbestände, auch häufig in den tiefen 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.
