Many members of the Lancashire Botany Group are also members of The Botanical Society of Britain and Ireland which is for everyone who is interested in the flora of Britain and Ireland. The society traces its origins back to 1836, when it was founded as the Botanical Society of London.
From its earliest days it has welcomed both professional and amateur members, and the society remains the biggest and most active organisation devoted to the study of botany in Britain, Ireland, the Channel Isles and the Isle of Man.
The BSBI produces national Atlases and county Floras of the distribution of plants. It publishes the New Journal of Botany and holds conferences and field meetings. Members are kept informed by a newsletter three times a year and are invited to make use of its system of county recorders and national referees who can help with the identification of plants.
Lancashire Botany Group is an independent group that sends records to the BSBI for inclusion in the national data base.
