Table 7. Counts of squares and climat ic means Attribute (a) Counts GB Min Max Explanation IR 0 985 Ireland Counts of 10-km squares 0 2805 Great Britain and Isle of Man CI 0 14 Channel Islands (b) Climatic means Mean values for 10-km squares Tian - 1.3 7.0 January mean temperat ure (°C) Tjul 10.4 17.0 July mean temperature (°C) Prec 553 32 18 Annual precipitation (mm) Climatic means Climat ic values for plants were calculated as t he mean climate of the 10-km squares where they occur in Britain, Ireland and the Channel Islands, averaging over the squares enumerated for the counts. Climate data for 10-km squares were taken from baseline climate summaries of t he UK Climate Impacts Programme (Hu Ime & Jenkins, 1998). These baseline summaries were const ructed by interpolat ion of daily weat her measurements from individual met stat ions, averaged over the 30-year period 1961- 1990 (Barrow et al., 1993).
HA BI TA T A TTRIB UTES Coastal species Species are deemed to be coastal if 80% of occupied squares are on the coast and if they depend on coastal habitat. Most coastal species have Ellenberg salt values (S values, defi ned below) greater than 0. Those with Ellenberg S = 0 were scrutinized carefully to ascertain whether their habitat was indeed coastal. Broad Habitats The preferences of species for Broad Habitats of the UK BAP are listed in the column labelled Br Habitats. Species' main habitat (s) are_list ed. No species is deemed to have a preference for more t han four habitats. Minor habitats are ignored. For more informat ion about Broad Habitats and species' preferences, refer to the Appendix.
