Botanical Society of the British Isles
The Botanical Society of the British Isles (BSBI) is a scientific society for the study of flora, plant distribution and taxonomy relating to Great Britain, Ireland, the Channel Islands and the Isle of Man. The society was founded as the Botanical Society of London in 1836. It includes both professional and amateur members and is the largest organization devoted to botany in the British Isles. Its history is recounted in David Allen's book The Botanists.
The society publishes handbooks and journals, conducts national surveys and training events, and hosts conferences. It also awards grants and bursaries, sets professional standards (with Field Identification Skills Certificates (FISCs)), and works in an advisory capacity for governments and NGOs.
The society is managed by a council of elected members, and is a Registered Charity in England & Wales (212560) and Scotland (SC038675).
The BSBI publishes a scientific periodical, New Journal of Botany (formerly Watsonia). The journal has a north-western European scope covering vascular plants, their taxonomy, biosystematics, ecology, distribution and conservation, as well as topics of a more general or historical nature".
The society produced the Atlas of the British Flora in 2002, the Vice-county Census Catalogue of the Vascular Plants of Great Britain in 2003, and publishes the BSBI Handbooks series.

Publications dealing with rare plants 
The BSBI's attitudes to publication of details of locations of rare plants have changed over time. In 1991, publicly criticised the author John Fisher, for writing "A Colour Guide to Rare Wild Flowers", a book which gave details of the locations of a selection of rare plants, stating that it was not in the interests of conservation. Following this criticism, Fisher resigned his membership of the BSBI. Fourteen years later, David Pearman, the Society's General Secretary, contrasted the way in which Fisher was, as Pearman termed it, "hounded out", with the more open attitudes that had then taken hold. In more recent times, the BSBI has produced or supported the production of a number of County Rare Plant Registers, books which list all known locations for all rare plants in their county of coverage.
