In 2010, the updated Global Strategy for Plant Conservation (GSPC) of the U.N. Convention on Biological Diversity included as its first target (Target 1) the need for ‘An online flora of all known plants.’ With this background in mind, in January 2012 in St Louis, Missouri, U.S.A., representatives from four institutions: the Missouri Botanical Garden, the New York Botanical Garden, the Royal Botanic Garden Edinburgh, and the Royal Botanic Gardens, Kew (all members of the Global Partnership for Plant Conservation, GPPC) took the initiative to meet and discuss how to achieve GSPC Target 1 by 2020. The meeting resulted in a proposed outline of the scope and content of a World Flora Online (WFO), as well as a decision to form an international consortium of institutions and organisations to collaborate on providing that content.
The WFO project was subsequently launched in India, at an event held during the 11th Conference of the Parties to the Convention on Biological Diversity in October 2012 where the COP also adopted a decision welcoming the WFO initiative. In January 2013 a Memorandum of Understanding on the WFO was opened for signature. Up to the end of March 2023, 51 institutions and organisations had signed the MOU.
The WFO is an open-access, Web-based compendium of the world’s plant species. It is a collaborative, international project, building upon existing knowledge and published Floras, checklists and revisions but will also require the collection and generation of new information on poorly know plant groups and plants in unexplored regions.
The project represents a major step forward in developing a consolidated global information service on the world’s flora.
