By county (BSBI)
The Botanical Society of Britain and Ireland collect data at the county level. To facilitate this they make recording cards available for each county in Britain and Ireland. Recording cards have a general cover sheet and then a second sheet that is customised to include only those species that occur in each county and are not too rare.
If you are very experienced in identifying vascular plants, these cards may be valuable tool for recording. BSBI Recording Cards by county
We encourage those interested to get involved with the BSBI. There are 40 Irish BSBI country recorders who have responsibility for collating and submitting data for their county.
