An analysis of the numbers and distribution of seabirds within the British Fishery Limit aimed at identifying areas that qualify as possible marine SPAs 2010
This report describes an analysis of European Seabirds at Sea (ESAS) data, conducted to identify and delineate seabird aggregations within the British Fishery Limit that might qualify as SPAs. ESAS data used in this analysis were collected using standardised transect methods from boats over more than 30 years. All years of data were combined and then split by species and season in order to link possible SPAs to key stages in the seabirds' annual cycle. Some data were excluded because their quality might have been compromised. A correction factor was applied to adjust numbers of species where detection probability decreased with distance from observers.
