8.2.3.4. Kalkreicher, trockener Hackfruchtacker

Eragrostion

Description

Phyonomy and Ecology (© Delarze & al. 2015)

Ähnlich wie der eben beschriebene Lebensraum Panico-Setarion (8.2.3.3) wird auch diese Einheit von Gräsern und Amaranthgewächsen dominiert, die erst zu Beginn des Sommers keimen und gegen Ende der Vegetationszeit fruchten. Die kurze Entwicklungszeit verlangt ein hohes Mass an Wärme. Es handelt sich um Unkrautfluren, die basenreiche, lockere Böden besiedeln und an Trockenperioden angepasst sind. Ausser in trockenwarmen Hackäckern findet man diese Einheit oft an Wegrändern und entlang von Feldmauern, auf flachgründigen oder sehr wasserdurchlässigen Bodenpartien. Im Frühling blühen hier oft auch halbruderale Arten von Pionierrasen wie Erodium cicutarium, Erophila verna, Holosteum umbellatum, Petrorhagia prolifera (vgl. 4.1.1, Alysso-Sedion).

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.
