The BSBI Atlas of the British and Irish Flora is a major publication project that has previously appeared at 40-year intervals. It is one of the most important sources of information on the distribution of British plants, and is widely used by researchers and conservationists.
With computers it is possible to keep the maps updated on an 'ad hoc' basis, so the decision has been made to age-band records every 10 years, starting in 2000 (just after the work for Atlas 2000 completed). This means that we are now at the start of the third age band since the last published Atlas. The third Atlas will appear once analysis has been done on the 2000-2019 data.
All record submissions for the Atlas were completed at the end of 2019, so you will no longer find the pages here that were designed to help you in your recording efforts. There will be some new projects and initiatives for the county coming soon, but these will be detailed and supported on the new Hants Plants web site currently under development.
The BSBI Distribution Database offers everyone an opportunity to map the distribution of the British flora at a tetrad (2km x 2km) resolution, giving a much better impression of how frequent our more localised and declining species really are. Inevitably national coverage will be patchy for many years to come, but the pieces of the jigsaw will gradually drop into place.
