Annex I habitats that are a primary reason for selection of this site
|4030 European dry heaths|
|Berwyn contains the largest stands of upland European dry heath in Wales. The dry heath is characteristic of Berwyn’s more easterly location and less oceanic climate than the other major Welsh uplands, and consists principally of NVC type H12 Calluna vulgaris – Vaccinium myrtillus heath, with frequent crowberry Empetrum nigrum and occasional cowberry Vaccinium vitis-idaea. Other heath vegetation present includes areas of H18 Vaccinium myrtillus – Deschampsia flexuosa heath and in some areas stands of damp H21 Calluna vulgaris – Vaccinium myrtillus – Sphagnum capillifolium heath. These latter heaths occur in an intermediate position between the drier heaths and blanket mire and support occasional plants of lesser twayblade Listera cordata.|
|7130 Blanket bogs (* if active bog) * Priority feature|
|Berwyn supports the most extensive tract of near-natural blanket bog in Wales. Much of the blanket bog vegetation is dominated by NVC type M19 Calluna vulgaris – Eriophorum vaginatum blanket mire, with crowberry Empetrum nigrum and an often extensive hypnoid moss cover; within this community cloudberry Rubus chamaemorus is found close to the southernmost limit of its British range. On deeper peats, there are smaller stands of M18 Erica tetralix – Sphagnum papillosum mire, some of which exhibit distinctive surface patterning. The mire vegetation shows transitions to heather-dominated dwarf-shrub heath.|
