Seabird 2000 (EUROBIS)

The data was gathered by over 1000 surveyors mainly between the years 1999 and 2003 from both coastal and inland colonies. The main objectives of the survey were: to obtain distribution and population information for all 25 species of seabird that regularly breed in the UK; to get baseline figures for those species that have been surveyed poorly up to now.

To meet these objectives a set of count sections were set up throughout Britain and Ireland and counts were made for all species. The dataset comprises detailed counts of seabirds together with: habitat information, predator information, count units, weather conditions on the day of the count. The spatial coverage was dependent on species with colonial nesting seabirds having virtually complete coverage; whereas, other species, notably some gull species having much less coverage.
