54.1112 - Philonotis-Saxifraga stellaris springs

Classification des habitats du Paléarctique (2001)

Description

Bryophyte dominated spring communities of alpine, subalpine, boreoalpine, arctoalpine, and sometimes upland, well-lit, lime-poor cold waters of the northern Palaearctic mountains and hills, of the Alpine system and of the great Hercynian ranges, mostly dominated by Philonotis seriata, Bryum schleicheri or, in the north and west, Philonotis fontana, with a vascular species cortŠge marked by arcto-alpine species, among which Saxifraga stellaris is usually prominent. Somewhat intermediate between the communities of unit 54.1111 and those of units 54.1113 and 54.1114, they extend to relatively low upland regions in northern Europe, in the British isles, and, as glacial relicts, in the Hercynian ranges and their periphery.
