Datganiad

Part 1- Study sites were selected mainly on the basis of notable topographic features such as areas of limestone pavement, cliffs etc. A number of unlocalised 10km square records were also searched for. Microscopic identification, chemical spot tests, UV fluorescence, thin-layer chromatography and reference to lichen floras and relevant taxonomic papers were used to identify species whilst referees in Britain and abroad were consulted to rule on critical taxa. A species list was completed for the site with each taxon given a frequency rating on the DAFOR scale. Specimens resulting from the work have been lodged with the National Museum of Wales, Cardiff. Nomenclature follows Coppins 2002 and information on the conservation status of lichens is based on Woods and Coppins 2003. Part 2- Trials for establishing a baseline for Common Standards Monitoring of lichens at Pen Y Gogarth/Great Ormes Head SSSI carried out over two days in good weather. Two lichen habitats of considerable importance were chosen- limestone pavements and dry inland limestone cliffs. Two monitoring formats were employed- site attribute tables for indirect lichen habitat monitoring and direct monitoring proformas for easily recognisable notable species or communities.
