Over the last couple of days, there have been busy threads on both the BWARS and NFBR Facebook groups concerning record verification. It all started with a question concerning the distribution of Anthophora plumipes, a relatively easily recognised solitary bee that flies in early spring and whose distribution is well-known.
The map that was produced on the NBN (Figure 1) showed vastly wider distribution than is shown in reliable data compiled by BWARS (Figure 2) but not currently available through the NBN. The difference is obvious! The data in question was compiled by the ‘Great British Bee Count’ run by ‘Friends of the Earth’. In essence, the data are junk as they stand! Sadly, an awful lot of well-meaning people have been encouraged to participate in what seems to me to be little more than a publicity stunt. No thought seems to have been given to data verification or to the impact poor data can have on the work and outputs of long-established biological recording schemes.
