Atlas 2020

The first atlas of the British and Irish flora, published in 1962, pioneered the use of ‘dot-maps’ aligned to the OS grid. Read about the influence that it had in this paper published  in New Journal of Botany.

A repeat atlas was published in 2002 based on fieldwork carried out from 1987-1999.

BSBI is now producing a third atlas, Atlas 2020, which will be published after fieldwork has been completed in 2019.

Atlas 2020 will provide:

  • Maps for both native and introduced taxa
  • Interactive maps able to display frequency and distribution at a variety of scales
  • Analyses of changes, summarising the state of the British and Irish flora in 2020. 

Getting involved

  • Volunteer to record a 10 x 10 km (hectad) square – it’s a great way to improve your identification skills
  • Record a square on your holiday
  • Adopt an ‘under-recorded’ area (e.g. remote islands, mountains, etc.)
  • Attend a BSBI field meeting

If you are interested in getting involved, please contact the relevant country officer (listed below), who will direct you to the relevant county recorder
