Download full pdf synopsis: BG2E
This is quite a heathy bog community with a dwarf shrub layer dominated by Calluna vulgaris alongside which grow some stems of Erica tetralix. Tussocks of Eriophorum vaginatum are a constant feature, as are tufts of Eriophorum angustifolium and Trichophorum cespitosum/germanicum. Frequent companions are Potentilla erecta and Molinia caerulea. Beneath all this, in the bryophyte layer, hummocks of Sphagnum capillifolium are found together with pale green patches of Hypnum jutlandicum. Sphagnum papillosum and threads of Odontoschisma sphagni are frequent.
This is a community of deep, ombrogenous, oligotrophic, wet and acidic peat soils in the uplands.
No sub-communities have been described for this community.
The Calluna vulgaris – Eriophorum spp. bog may be viewed as intermediate between two other upland blanket bog communities, the HE3F Calluna vulgaris – Eriophorum vaginatum heathy bog and the BG2F Trichophorum cespitosum/germanicum – Eriophorum angustifolium bog/heath. Trichophorum is less frequent in HE3F and pleurocarpous mosses are much more prevalent, whilst in BG2F, Eriophorum vaginatum is only occasional.
Almost all examples of this habitat will qualify as EU HD Annex I habitat 7130 Blanket bog (active)*. This is on average a moderately species-poor grassland community.
These bogs are used as rough grazing land, typically for sheep, and often occur within commonages. The main threats are overgrazing, erosion, burning and afforestation. Turf-cutting and drainage may also occur on deeper peats.
