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.

The nomenclature used follows that of the New Flora of the British Isles (Third Edition) by Clive Stace.
