4.3.5. Borstgrasrasen

Nardion

Description

Phyonomy and Ecology (© Delarze & al. 2015)

Die Borstgrasrasen erkennt man an der Dominanz des Borstgrases (Nardus stricta), das seinen Namen den borstigen, früh vergilbenden Blättern verdankt. Die Bestände sind kurzwüchsig und relativ gleichförmig. Einige Varianten sind mit vielen bunt blühenden Arten versehen. Sie wachsen auf sauren (oder zumindest oberflächlich versauerten), ausgewaschenen Böden. Häufig handelt es sich um ungedüngte Alpweiden. Das Nardion erstreckt sich von der subalpinen bis in die untere alpine Stufe; hie und da findet es sich auch noch in tieferen Lagen auf extensiv genutztem Weideland.

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.
