4.3.3. Rostseggenhalde

Caricion ferruginae

Description

Phyonomy and Ecology (© Delarze & al. 2015)

Rostseggenhalden sind mehr oder weniger geschlossene Hangrasen, geprägt durch langhalmige Grasartige, wie die Rostsegge (Carex ferruginea), der Violettschwingel (Festuca violacea) oder das Bunte Reitgras (Calamagrostis varia), die, aus Distanz betrachtet, scheinbar sehr dicht stehen. Die feinen Blätter dieser Arten lassen aber viel Licht durchdringen, was das Aufkommen einer artenreichen Begleitflora ermöglicht. Im Gegensatz zu den Blaugrashalden ist das Bodenrelief viel gleichmässiger gestaltet. Diese Rasen bedecken kalkige, meist nordexponierte Steilhänge, die stets gut durchfeuchtet sind. In den niederschlagsreichen Lagen der nördlichen Kalkalpen kommen die Rostseggenhalden besonders häufig vor, insbesondere auf tonreichen Schiefersubstraten. Die Einheit findet sich in der subalpinen und alpinen Stufe. In den unteren Lagen wachsen sie auf natürlich gehölzfreien Stellen (z.B. Lawinenrutschhänge).

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.
