3.4.2.2. Silikatfelsflur

Androsacion vandellii

Description

Phyonomy and Ecology (© Delarze & al. 2015)

Als Silikatfelsflur wird die lockere, pionierhafte Vegetation auf Silikatfels und grossen Silikatblöcken bezeichnet. Kleine Risse und Klüfte ermöglichen die Bewurzelung durch Gefässpflanzen. Im Gegensatz zur Kalkfelsflur finden wir hier neben den Gefässpflanzen häufig auch trockenheitliebende Moose und Flechten. Zu den Standorteigenschaften gehören intensive Trockenperioden und extreme Temperaturschwankungen. Der Lebensraum ist praktisch in allen Höhenlagen anzutreffen. Von der kollinen bis zur nivalen Stufe folgen einander verschiedene Gesellschaften (Assoziationen).

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.
