4.6.1. Queckenbrache

Convolvulo-Agropyrion

Description

Phyonomy and Ecology (© Delarze & al. 2015)

Diese dichten, halbruderalen Grasbestände sind von Weitem am blaugrünen Blattschimmer der Quecken (Elymus repens, bzw. E. hispidus in den inneralpinen Tälern) zu erkennen. Diese rasch durch unterirdische Ausläufer sich ausbreitenden Grasarten lassen für Begleitarten kaum Platz übrig. Ihre dichte Streuschicht verhindert zudem das Aufkommen der meisten Annuellen und anderer niederwüchsiger Pflanzen. Die Gruppe entwickelt sich meist auf aufgelassenen Ackerterrassen und Feldrändern sowie an Strassenrändern, die unregelmässig gepflegt werden. Sie vermag sich lange und erfolgreich gegen die Gehölzentwicklung zu behaupten, umso besser, je dichter ihre Grasnarbe ausgebildet ist. Der Boden ist nährstoffreich, gut drainiert und trocknet oft aus. Die Einheit gedeiht in den tiefen Lagen und in den wärmeren, inneralpinen Trockentälern.

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.
