Records submitted to the Bumblebee Conservation Trust's BeeWalk project, a standardised transect-walking abundance-based survey focussed on bees in the genus Bombus (bumblebees) and Apis (honeybees), with occasional records of other bee species. No particular intentional bias in habitats surveyed. Records cover Great Britain, the Channel Islands and Isle of Man (but not Northern Ireland). North/mid Wales and north-west Scotland are comparatively under-represented in the dataset. Additional information, including a detailed protocol, survey analysis reports, data entry form, etc, can all be found at www.beewalk.org.uk
