2.2.4. Übergangsmoor

Caricion lasiocarpae

Description

Phyonomy and Ecology (© Delarze & al. 2015)

Die Übergangsmoore bilden Bestände aus Sauergräsern (insbesondere Seggen), die auf die Übergänge zwischen den äusserst nährstoffarmen (dystrophen) Hochmooren und den etwas mineralienreicheren, aber immer noch oligotrophen Standorten spezialisiert sind. Diese finden sich typischerweise in Senken in der Nachbarschaft von Hochmooren. Die Bestände bilden manchmal flossartig in eine Wasserfläche von Tümpeln hinausragende Schwingrasen. Die Einheit wächst aber auch in wasserhaltigen Vertiefungen der Kernzone von Hochmooren (Schlenken) oder bildet Übergangsmoore, die zwischen den Hochmooren und den mineralienführenden Kleinseggenrieden liegen. Das Substrat ist reich an organischem Material (torfig), besitzt reduzierende (sauerstoffarme) Eigenschaften und enthält nur wenige Nährstoffe und Basen.

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.
