SPECIES LIST FROM WORKSHOP DAY 1, DAY 2 AND FINAL WITHIN THEMATIC GROUP CONSENSUS The scores (Initial Overall impact on biodiversity score) were provided by the experts within the five thematic groups at the first stage of

consideration of the species. The scores were used for guidance only and should be viewed with caution, the discussions within and between thematic group experts provided the context of the scores and enabled the initial ranking (which were subsequently reviewed and moderated) of the species. These initial scores represent those provided in the preliminary assessment prior to the workshop (see ticks in Final List, Day 2, Day 1 and Preliminary columns for the point at which the species were included within the process) the scores listed below were the scores attributed at the first stage that the species was included for consideration. Following review through the consensus process the scores were altered, therefore the scores here and those in Table 5.1 are not the same. The scores in Table 5.1, while also for guidance only, were the final scores from the consensus following review and moderation through expert discussions. However, the final ranking of the species was

determined by consensus through discussions across all thematic groups; the scores were not altered and so do not reflect the final rank. Some of the cells remain blank because many of the species were only included in preliminary stages and because of the number of species and time constraints the experts were unable to provide all this information for species that were subsequently removed from consideration.
