The separation of PMGRP fromboth Fens PHT and wet Lowland Heathland PHT is complicatedby the fact that the definitions are not compatible. Moreover,there is some question as to whether the definition properlyreflects the habitat that was intended.ExplanationThe wetlands of the Culm NA will have been recordedaccurately.Elsewhere, we consider that the interpretation is good so longas the problem of the overlap with the two other PHTsmentioned above is ignored. In particular, there is often somedifficulty with the separation of wet LH and this habitat.Certain problematic mires will have been recorded as thewrong PHT, but they will be PHT, which is the important point.CommentsThe map of the PMGRP in the Culm NA we assess as verygood, the rest of the county we assess as good, accepting thelimitations discussed above.Appendix 4 - Information Relating to Priority Habitat TypesCounty Wildlife Sites Criteria
