2.4.1. Offene Hochmoore

Sphagnion magellanici

Description

Phyonomy and Ecology (© Delarze & al. 2015)

Offene Hochmoore bestehen vorwiegend aus einem schwammigen Teppich wassergetränkter Torfmoose, auf dem verstreut kleinblättrige Heidekrautgewächse und schmalblättrige Sauergräser wachsen. Die Torfmoose sind durch ihr kontinuierliches, vom Grundwasser unabhängiges Wachstum die treibende Kraft für die Entstehung der Hochmoore, und sie zeigen im Kern des Moores meist die grösste Aufwölbung. Auch im kleinen Massstab betrachtet, weist die Hochmoorfläche kein gleichmässiges Wachstum auf. Es wechseln sich höckerartige Bulten mit nassen Schlenken ab; Letztere meist mit Vegetation des Rhynchosporion (2.2.4). Der grosse Mangel an verfügbarem Stickstoff begünstigt die Existenz fleischfressender Pflanzen (Drosera) und mykorrhiza-abhängiger Heidekrautgewächse.

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.
