5.3.7. Moor-Weidengebüsch

Salicion cinereae

Description

Phyonomy and Ecology (© Delarze & al. 2015)

Die in Mooren anzutreffenden Gebüsche aus kugelwüchsigen Weiden (Salix aurita, S. cinerea) werden oft von Birken (Betula pendula, B. pubescens) begleitet. Die Sträucher wachsen 3 bis 5 m hoch und besiedeln nasse, moorige Standorte mit schweren tonig-lehmigen und häufig sauren Böden mit mangelnder Durchlüftung. Die Krautschicht besteht vorwiegend aus Nässezeigern und wird dominiert von grossen Gräsern (Phragmites australis, Phalaris arundinacea, Calamagrostis canescens) oder Seggen (Carex elata, C. acutiformis, C. riparia). Die Einheit findet man am Rande von Moorflächen, an Ufern von Altwassern, aber auch in sumpfigen Mulden oder auf nicht mehr bewirtschafteten Streuwiesen. Es handelt sich oft um Übergangstadien zum Erlenbruchwald (6.1.1), seltener auch zum Grauerlen-Auenwald (6.1.3). Die Einheit umfasst auch die säurezeigenden Weidengebüsche und Weiden-Zwergbirken-Gesellschaften (Betulo humilis-Salicetum repentis).

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.
