4.3.1. Blaugrashalde

Seslerion

Description

Phyonomy and Ecology (© Delarze & al. 2015)

Die Blaugrashalden sind blumenreiche alpine Rasen mit grosser Florenvielfalt und auffallend hohem Anteil an Leguminosen. Strukturgebend sind horstbildende Grasartige, namentlich das Blaugras (Sesleria caerulea) und die Horstsegge (Carex sempervirens). In Hängen mit Fliessböden (Solifluktion) bilden sie oft treppenartige Rasen. Böden sind relativ flachgründig, steinig und trocknen rasch aus (Rendzina). Blaugrashalden wachsen an sonnigen Hängen über einer Gesteinsunterlage aus Kalk oder Dolomit. Das ökologische Optimum liegt in der alpinen Stufe (2000 bis 2500 m), aber Blaugrashalden finden sich auch, auf Sonderstandorten bis in die montane Stufe.

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.
