BSBI
Maps Scheme The BSBI Maps Scheme produces dot maps
showing the distribution of vascular plants and charophytes in
the British Isles, updated at weekly intervals. It was launched
in 1950 and is now based on a ten-year cycle of recording, so
the black dots at any point in time show only the records that
have come in so far this decade.
The BSBI Maps Scheme database was commissioned by David Pearman,
designed by Alex Lockton and constructed by Alan Hale and Bob
Ellis. Quentin Groom & Alex Lockton manage the data and maintain
the maps. The project is funded by the BSBI.
