County Wildife Site Criteria for Cornwall Appendices

The National DefinitionGoodReliability of PHTInterpretationAverageCommentThe definition of this PHT is rather imprecise and open tointerpretation, but that is bound to be the case. Some moreprecise standard on what separates a wood pasture and parklandof PHT quality from one that does not would be useful.Local BAP VariationNoneExplanationThere is one method that may be reliably used to identify thisPHT: Phase 1 maps in combination with a detailed site report.Unfortunately, not every area marked on a Phase 1 map asparkland is necessarily an area that would be considered to bePHT, nor do we have detailed information relating to some ofthe sites.We have adopted the approach that we would only use acombination of Phase 1, Ordnance Survey maps and site reportsto map this PHT in Cornwall.Those that have been mapped for no other reason than theyappear as parkland on a Phase 1 map have been accorded aPriority Qualifier of C. There are also small number of areas ofopen land with trees that are known to been in existence forover a century that have also been included if they were notalready included on the Phase 1 maps (these may be referred toas parks or deer parks). They too have been accorded a PriorityQualifier of C. The Priority Qualifier has been upgraded to Awhere further information is available.Our method may give a biased result in that the Wood-pastureand Parklands PHT may be over-represented. On the otherhand, the use of Phase 1 as the prime source has allowed us toproduce results that are transparent. That is, the allocation toPHT follows a clear and simple method where the PHT arisesfrom a direct correspondence with the original classification.SummaryDefinitely is: parklands which have documentation of significantfeatures associated with this PHT. This would normally be inthe form of evidence of veteran trees.Overall AssessmentAverageProbably is: parklands without significant documentation.CommentsThe map that has been produced will clearly show more PHTthan further study would reveal. Nevertheless, there is a coreof mainly large areas such as Lanhydrock and Boconnoc whichare know to be of value, together with a raft of minor sites thatrequire further study to clarify their importance.Appendix 4 - Information Relating to Priority Habitat TypesCounty Wildlife Sites Criteria
