The EN SAC maps for the Tamar werevery detailed.There are other surveys such as the CWS, Phase 1 and theOrdnance Survey symbols on the 1:10 000 maps, but only theCWS records were used, and then only sparingly.CommentThe definition is clear.ExplanationThe definition of Coastal Saltmarsh is clear and there isadequate detailed information for the whole county. Moreover,the identification of saltmarsh is relatively easy from aerialphotographs and Ordnance Survey maps.CommentsWe consider that the Coastal Saltmarsh PHT interpretation forCornwall is precise and that the map shows the distributionwith a high degree of accuracy.Appendix 4 - Information Relating to Priority Habitat TypesCounty Wildlife Sites Criteria
COASTAL SAND DUNES PHTGeneral DescriptionCoastal sand dunes develop where there is an adequate supply of sand in the intertidal zone andwhere onshore winds are prevalent. The critical factor is the presence of a sufficiently large beachplain whose surface dries out between high tides. The dry sand is then blown landwards anddeposited above high water mark, where it is trapped by specialised dune-building grasses which growup through successive layers of deposited sand.Fixed dune grassland forms largely closed swards where accretion is no longer significant, the surfaceis stabilised and some soil development has taken place. These communities mentioned are, or havebeen, maintained by grazing, whether by domestic stock or by rabbits.National ContextMajor dune systems are widely distributed within Britain. The total area is 53 000 ha (56 000 ha UK).The Sand Dune Survey of Great Britain (1993-1995) gives the total area of sand dunes as about 12000 ha in England and 8000 ha in Wales. The ongoing Sand Dune Vegetation Survey of Scotlandindicates that there may be as much as 48 000 ha of dune and machair in Scotland, of which 33 000 hais dune.Area of PHT in Cornwall (ha): 10301.9% National TotalNumber of Sites: 31The habitat is: Fairly rareDistribution by Administrative DistrictDistrict P K CK R CN NC ΣNumber 10 5 8 5 0 3 31Area (ha) 320 30 540 20 0 120 1030Distribution by Natural AreaDistrict Pe Lz CKG BM Cu ΣNumber 0 5 26 0 0 31Area (ha) 0 30 1000 0 0 1030For this habitat the threshold is 1.0 haAppendix 4 - Information Relating to Priority Habitat TypesCounty Wildlife Sites Criteria
