5.2.3. Hochgrasflur des Gebirges

Calamagrostion

Description

Phyonomy and Ecology (© Delarze & al. 2015)

Die Dominanz der Gräser charakterisiert diese spezielle Ausprägung einer «Hochstaudenflur». Es sind dies: Calamagrostis villosa und Agrostis schraderiana in der subalpinen Stufe und Calamagrostis arundinacea in der montanen Stufe (v.a. im Tessin). Der Boden ist kalkarm, aber dennoch basen- und nährstoffreich. Er ist zeitweilig mit Wasser gut versorgt, im Gegensatz zu den Alpendostfluren (5.2.4, Adenostylion) aber auch kurzen Trockenperioden unterworfen. Der Boden enthält weniger organisches Material als bei den Weidenröschenfluren (5.2.2, Epilobion angustifolii). Die Einheit trifft man in niederschlagsreichen Gegenden, in Lawinenrunsen und an sonnigen, waldfreien Steilhängen.

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.
