The BSBI aims to involve everyone interested in the flora of Britain and Ireland. Founded in 1836 as the Botanical Society of London, it has grown to become the primary organisation for botany enthusiasts in Britain, Ireland, the Channel Isles, and the Isle of Man. It supports both professional and amateur botanists, emphasizing inclusivity and active engagement in botanical study.
The BSBI Research Grant, managed by the Science and Research Committee, offers small grants to fund research aimed at expanding knowledge about the flora of Britain and Ireland. The grant supports a wide range of scientific inquiries including taxonomy, systematics, evolution, various aspects of ecology, population and ecological genetics, phytogeography/phylogeography, interactions between plants and animals, including plant biochemistry, and conservation biology. This initiative underscores the BSBI's commitment to fostering research that advances the understanding of plant life in the specified regions.
