Die Vegetation der Moore des Brockengebietes: II. Pflanzengesellschaften ombrotropher Moorbereiche, der Torfstiche und Bruchwälder

Abstract

In the second part the vegetation of bogs of the Brocken is described. Stands of the Sphagnetum magellanici screen the open bog sites. The Sphagnetum magellanici can be divided into six subassociations, which depend on different water tables and which can again be divided partly in two variants of ombrotrophic and minerotrophic sites. The Dicranella cerviculata-Eriophorum vaginatum-community grows as a pioneer-community onopen, ombrogenous peat. Near the brink of the bogs and on drained areas occurs the Piceo-Vaccinietumuliginosi, which has some floristical and ecological similarities with the Pine-carr vegetation (Calamagrostio villosae-Piceetum, variant of Dicranum scoparium) of the brinks of the bogs. In a different variant Pine-carr vegetationalso occurs on minerotrophic sites (Calamagrostio villosae-Piceetum, variant of Sphagnum fallax).
