4.4.1. Kalkreiches Schneetälchen

Arabidion caerulae

Description

Phyonomy and Ecology (© Delarze & al. 2015)

Die Kalk-Schneetälchen sind durch einen lückigen Teppich aus Rosettenpflanzen gekennzeichnet und finden sich an Stellen, die vom Schnee besonders lange bedeckt sind. Im Randbereich sind oft die kriechende Stumpfblättrige Weide (Salix retusa) und die Netzweide (Salix reticulata) dominant. Die Vegetation besiedelt einen kalkhaltigen, ständig feuchten Boden. Er ist deutlich skelettreicher und daher auch drainierender und beweglicher als derjenige der sauren Schneeböden. Das ist der Grund, weshalb Moose hier eher schwach vertreten sind und erst in den humusreicheren Übergangszonen zum Salicion herbaceae (4.4.2) verstärkt auftreten.

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.
