4.2.3. Insubrischer Trockenrasen

Diplachnion

Description

Phyonomy and Ecology (© Delarze & al. 2015)

Die Einheit zeichnet sich durch eine Vielfalt an wärmeliebenden Gräsern mit unterschiedlichen Wuchsformen aus, mit unterschiedlichen Blattbreiten, Horstgrössen und Blütenständen. Diese verschiedenen Gräser bilden häufig sehr heterogen gestaltete Rasenbestände, zusammen mit der niedrigen Segge (Carex humilis) und anderen trockenresistenten Gewächsen. Der Verband ist ausschliesslich südlich der Alpen anzutreffen, wo ein vergleichsweise mildes Klima herrscht (mittlere Jahrestemperatur über 10 °C). Das Artengefüge besiedelt sowohl kalk- als auch silikathaltige Unterlagen.

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.
