When undertaking an appropriate assessment of impacts at a site, all features of European importance (both primary and non-primary) need to be considered.
Annex I habitats that are a primary reason for selection of this site
|7110 Active raised bogs * Priority feature|
|Cors Fochno (also known as Borth Bog) lies on the south side of the Dyfi estuary in Wales and forms a component part of the Dyfi Biosphere Reserve. Although a substantial part of the former peatland complex has been taken for agriculture, the surviving core area supports the largest expanse of primary near-natural raised bog in an estuarine context within the UK. Extensive areas of patterned mire include occasional hummocks of the bog-mosses Sphagnum fuscum and, more rarely, S. imbricatum ssp. austinii, with hollows supporting S. pulchrum, greater sundew Drosera anglica, white beak-sedge Rhynchospora alba and bog-rosemary Andromeda polifolia. The extensive cover of bog-myrtle Myrica gale and maritime margins with black bog-rush Schoenus nigricans are distinctive features of this site in an England and Wales context. Areas of domestic peat-cutting peripheral to the dome are now actively regenerating and support a significant area of active bog vegetation; 7120 degraded raised bog also occurs widely around the periphery of the active core.|
|7120 Degraded raised bogs still capable of natural regeneration|
|Substantial areas of degraded raised bog occur peripheral to 7110 active raised bog at this extensive estuarine raised mire site. Included here are a range of vegetation types in which peat formation has been arrested as a consequence of intensive drainage followed in places by peat removal and/or agricultural management. The vegetation cover of these areas is varied and includes grazed and ungrazed Molinia – Myrica swards, reed Phragmites stands, rush Juncus pasture, wet woodland and scrub, drier areas of acid grassland and bracken Pteridium aquilinum, and improved grassland over archaic deep peat.|
