Annex I habitats that are a primary reason for selection of this site

  • 7110 Active raised bogs  * Priority feature

    This complex in north-west England is found in the plain of the Duddon estuary. In the southern part of the complex, where there are transitions from saltmarsh to bog, the vegetation is rich in the rare Sphagnum pulchrum. Further north a variety of raised bog conditions can be observed, from hand-cut and vigorously regenerating cuttings, to domes of uncut bog, which display significant areas of actively-growing bog vegetation.

  • This bog complex is within the tributary plains of the Duddon estuary in south Cumbria. The contiguity of the original peat domes has been severed by road construction and agricultural conversion. On some of the component bogs peat-cutting has left a drained surface which is now only partially 7110 active raised bog. The degraded raised bog is mostly dominated by purple moor grass Molinia caerulea, although pockets of raised bog plants including bog-mosses Sphagnum spp. offer good prospects for regeneration provided the hydrology is repaired. Degraded bog also occurs around the edges of discrete domes of active bog due to deep regional drainage and agricultural use of the surrounding land. There is no present-day peat-extraction on this site.
