South Pennine Moors
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
|4030 European dry heaths|
|The site is representative of upland dry heath at the southern end of the Pennine range, the habitat’s most south-easterly upland location in the UK. Dry heath covers extensive areas, occupies the lower slopes of the moors on mineral soils or where peat is thin, and occurs in transitions to acid grassland, wet heath and 7130 blanket bogs. The upland heath of the South Pennines is strongly dominated by heather Calluna vulgaris. Its main NVC types are H9 Calluna vulgaris – Deschampsia flexuosa heath and H12 Calluna vulgaris – Vaccinium myrtillus heath. More rarely H8 Calluna vulgaris – Ulex gallii heath and H10 Calluna vulgaris – Erica cinerea heath are found. On the higher, more exposed ground H18 Vaccinium myrtillus – Deschampsia flexuosa heath becomes more prominent. In the cloughs, or valleys, which extend into the heather moorlands, a greater mix of dwarf shrubs can be found together with more lichens and mosses. The moors support a rich invertebrate fauna, especially moths, and important bird assemblages.|
|7130 Blanket bogs * Priority feature|
|This site represents blanket bog in the south Pennines, the most south-easterly occurrence of the habitat in Europe. The bog vegetation communities are botanically poor. Hare’s-tail cottongrass Eriophorum vaginatum is often overwhelmingly dominant and the usual bog-building Sphagnum mosses are scarce. Where the blanket peats are slightly drier, heather Calluna vulgaris, crowberry Empetrum nigrum and bilberry Vaccinium myrtillus become more prominent. The uncommon cloudberry Rubus chamaemorus is locally abundant in bog vegetation. Bog pools provide diversity and are often characterised by common cottongrass E. angustifolium. Substantial areas of the bog surface are eroding, and there are extensive areas of bare peat. In some areas erosion may be a natural process reflecting the great age (9000 years) of the south Pennine peats.|
|91A0 Old sessile oak woods with Ilex and Blechnum in the British Isles|
|Around the fringes of the upland heath and bog of the south Pennines are blocks of old sessile oak woods, usually on slopes. These tend to be dryer than those further north and west, such that the bryophyte communities are less developed (although this lowered diversity may in some instances have been exaggerated by the effects of 19th century air pollution). Other components of the ground flora such as grasses, dwarf shrubs and ferns are common. Small areas of alder woodland along stream-sides add to the overall richness of the woods.|
