A6.105 Assemblages of breeding seabirds

Total number of breeding seabirds on the UK SPA network

 

To the total of seabirds occurring on sites holding major seabird assemblages (4,724,078 individuals) can be added those species that occur as qualifying species at sites where total numbers are less than 10,000 pairs. This amounts to a further 222,470 pairs of 14 species at 51 further SPAs, bringing the total number of seabirds breeding in the SPA network to 4,946,548 individuals. Note, however, that this is a minimum estimate of the number of breeding seabirds that benefit from the general habitat conservation provisions on seabird SPAs. This is because the total excludes non-qualifying seabird species which breed at sites classified for seabirds but where there are less than 10,000 pairs.
