Thedefinition refers to Phase 1 methodology and the original workis adequate to identify those few small areas that might beconsidered to be classic Upland Heathland.CommentsBodmin Moor is the only place in Cornwall where UplandHeathland may be found, because the majority of it lies abovethe limit of functional enclosure.. The NCC survey covers thenorth of the Moor and the Drage survey covers the south.We believe that the map of the small areas of characteristicUpland Heathland is accurate and that the other areas that liewithin the zone judged to lie above the limit of functionalenclosure allows an accurate assessmnet to be made.Appendix 4 - Information Relating to Priority Habitat TypesCounty Wildlife Sites Criteria
