Oroboreal acidocline grassland

English name: Oroboreal acidocline grassland

Description (English)

Grass, sedge, rush, bryophyte and lichen acidophile or acidocline communities of the higher summits of the boreal and arcto-alpine mountains, southwest to the Highlands of Scotland, the Lake District, northern England and northern Wales, submitted to diverse, though generally moderate, levels of snow cover and wind exposure, with resulting affinities to both the fairly chionophilous grasslands of the Alps Caricetea curvulae assembled in unit E4.31 and to the snowfield communities of unit E4.11; Juncus trifidus and Carex bigelowii are often present.
