4.1.2. Kalkfels-Pionierflur des Gebirges (Karstfluren)

Drabo-Seslerion

Description

Phyonomy and Ecology (© Delarze & al. 2015)

Diese Felsfluren bilden ein Gefüge aus vielen verholzten Kriechpflanzen, die südexponierte Kalksteinplatten spalierartig bewachsen. Im Gegensatz zu den Kalkfels-Pionierfluren der Tieflagen (4.1.1), enthalten sie nur wenige ein- bis zweijährige Pflanzen (Therophyten). Die Winter sind zu hart und die Frühjahrsbedingungen halten zu wenig lang an, als dass sich die Rosetten dieser Pflanzen entwickeln könnten. Die niederliegend wachsenden Pflanzen legen sich dicht an die Felsoberfläche, um von der dort tagsüber gespeicherten Wärme zu profitieren. Die Einheit kommt hauptsächlich in den Bergen vor, findet sich aber gelegentlich auch auf wenig besonnten und witterungsexponierten Felsen in tieferen Lagen. Sie bewächst auch Karrenfelder und stabile Geröll- und Grobschutthalden.

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.
