A total of 2,858 taxa have been recorded in Surrey at one time or another, although 92 of these taxa have not been recorded in the last 50 years. In the table below the 30 most widespread taxa are listed in order of the number of monads (out of 2,105 in Surrey) in which each plant is recorded. All counts are derived from MapMate (12/02/2016).
Distribution maps for all taxon in the British Isles can be found on the BSBI website.
Even the most widespread taxon Urtica dioica has only been recorded from 1,862 (88.5%) of the 2,105 monads in Surrey, suggesting that there is plenty of scope for recording it (and many more taxa) in a new monad.
