Notes on nomenclature

 
Scientific names of higher plant species are as used in Stace (1997). English names of higher plants are from Dony et al. (1986). Scientific names of lower plants are as used in Hill & Preston (2005) and Muñoz & Pando (2000), and Purvis et al. (1992). The names of National Vegetation Classification (NVC) types are taken from Rodwell (1991a,b, 1992, 1995, 2000). In some cases species names cited by Rodwell differ from those used in Stace (1997); where such inconsistencies occur, the names used in Rodwell (1991a, et seq.) have been retained. Marine species nomenclature follows Howson & Picton (1997).
 
The codes and names for habitat types, and species names, used in the present report are those adopted by Council Directive 97/62/EC Adapting to technical and scientific progress Directive 92/43/EEC on the conservation of natural habitats and of wild fauna and flora. These are the same names as those used in the Interpretation manual of European habitats (European Commission DG Environment 2003). The codes for species (which are not given codes in the text of the Directive) are those adopted in Appendix C of the guidance to the Standard Data Form for Natura 2000 sites (European Commission DGXI 1995).
 
Names of Annex I and Annex II features in the text include their codes and are highlighted in bold where appropriate. Annex I priority habitat types and Annex II priority species are preceded in headings and tables by an asterisk (*).
A list of cited acronyms is provided.
