In diesen locker besiedelten Schuttfluren (Deckungsgrad unter 50 Prozent) bildet das hochwüchsige Raugras (Achnatherum calamagrostis) auffällige, gelblich grüne Horste. Diese wärmeliebende Vegetation besiedelt instabile, meistens südexponierte Hänge in der kollinen bis montanen Stufe. Die Böden bestehen aus Kalk- oder Dolomitschutt mit einem kleinen Anteil an Feinerde. Neben Schutthängen kommt die Einheit auch auf trockenliegenden Schotterflächen in Flussauen vor.
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. |
