5.4.3. Subalpine Kalkheide (Erikaheide)

Ericion

Description

Phyonomy and Ecology (© Delarze & al. 2015)

Die Kalkheiden, deren Aussehen an die sauren Zwergstrauchheiden erinnert, sind durch die dominierende Schneeheide (Erica carnea) und eine reichhaltige Kalkflora gekennzeichnet. In der Strauchschicht überwiegen Nacktsamer und Heidekrautgewächse. Dieser Heidetyp ersetzt die sauren Zwergstrauchheiden auf den unausgereiften, nährstoffarmen Karbonatböden über kompaktem Kalk oder Dolomit. Das Substrat ist skelettreich, gut drainiert und trocken. Man findet die Einheit häufig auf Felskuppen und am Fusse wenig aktiver Geröllhalden. Die Einheit wächst in der subalpinen Stufe, stellenweise auch in der unteren alpinen Stufe. Nur wo kalte und feuchte mikroklimatische Verhältnisse herrschen (Kaltluftaustritte, Lawinenrunsen usw.), besiedelt sie auch Stellen in der montanen 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.
