Description
Undisturbed, or little disturbed, peat-forming bogs, often taking the shape of a convex lens. Such intact or nearly intact systems have become very rare or even exceptional. They are composed of a number of communities, which form and occupy the topological features of the bog. These communities are interrelated and function as a unit (part of complex X04), so that they cannot be regarded as separate subhabitats; their presence and combination, however, characterizes the various types of bogs. The subunits thus contribute to a description of individual bog systems. Vegetation of alliances Oxycocco-Empetrion hermaphroditi, Sphagnion medii and Sphagnion cuspidati. Typical species in the herb layer Eriophorum vaginatum, Oxycoccus palustris, Vaccinium spp.; in the moss layer dominance of genus Sphagnum spp., e.g. Sphagnum cuspidatum, Sphagnum fallax, Sphagnum palustre and Sphagnum magellanicum among others.
