7.1.6. Mesophile Ruderalflur (Steinkleeflur)

Dauco-Melilotion

Description

Phyonomy and Ecology (© Delarze & al. 2015)

Die Einheit weist eine lückige, aber artenreiche krautige Pflanzendecke auf, in der zweijährige Rosettenpflanzen und Leguminosen vorherrschen. Viele Arten können sehr hochwüchsig sein und bis zur Blüte Wuchshöhen von über 1,5 m erreichen (Melilotus spp., Oenothera spp., Isatis tinctoria usw.). Es handelt sich um eine Pioniervegetation mit hohen Lichtansprüchen, die sich auf Böden mit wenig organischem Material und geringem Stickstoffgehalt entwickelt. Sie besiedelt unbewirtschaftetes Land: kiesige Brachen, unbebautes Ödland, Eisenbahnschotter, alluviale Kiesbänke usw. Die Einheit ist mässig wärmeliebend, kann aber bis in trockenwarmen Gebiete vorkommen, wo sie gegenüber dem Onopordion (7.1.5) eher magerere Standorte besetzt. Die geringe Produktivität der Böden hemmt die Sukzession, die allmählich in Richtung geschlossener Graswiesen und Gebüschformationen abläuft.

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.
