4.2.2. Mitteleuropäischer Trockenrasen

Xerobromion

Description

Phyonomy and Ecology (© Delarze & al. 2015)

Wie bei der inneralpinen Felsensteppe (Stipo-Poion, 4.2.1.1) ist der Grasbewuchs sehr lückig, kombiniert mit vielen lichtliebenden, niederwüchsigen Arten. Ein zusätzliches Merkmal bilden die vielen Zwergsträucher mit wintergrünem Laub. Die Niederschläge sind hier regelmässiger als in den Felsensteppen, und die Temperaturschwankungen sind schwächer ausgeprägt. Da das subatlantische Klima grundsätzlich günstig für dichteren Pflanzenbewuchs wäre, findet sich das Xerobromion nur an sehr flachgründigen Stellen, meist in der Nähe von Felsplatten oder auf trockenen, steinigen Auenböden. Das Xerobromion hat sein Optimum in den tieferen Lagen, an sonnigen, kalkhaltigen Abhängen mit einer potenziell starken Verdunstung. In schattigen Lagen (z.B. in den Klusen des Juras) können Übergänge zu Blaugrashalden vorkommen.

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.
