7.1.4. Einjährige Ruderalflur

Sisymbrion

Description

Phyonomy and Ecology (© Delarze & al. 2015)

Die einjährigen Ruderalfluren besitzen eine krautige Pflanzendecke, die je nach Bestand sehr unterschiedlich zusammengesetzt ist und anders aussehen kann. Allen Beständen gemeinsam ist die Dominanz einjähriger, nährstoffzeigender Pflanzen. Die Vegetation enthält neben einjährigen oft auch zweijährige Arten, die im Herbst keimen und im darauf folgenden Frühling blühen. In den vielen Varianten dieser Einheit bilden die Kreuzblütler eine wichtige Komponente der Vegetation. Die Einheit bildet die ersten Sukzessionsstadien auf nicht mehr genutzten Flächen oder regelmässig gestörten, lockeren, steinigen Böden (Ackerränder, Deponien usw.). Die einjährige Ruderalflur ist kurzlebig und besiedelt gut drainierte, nährstoffreiche Böden, die oft wenig organisches Matrial aufweisen. Sie verlangt hohe sommerliche Temperaturen.

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.
