In 2019, the organisation had 2,316,699 public visitors at Kew, and 312,813 at Wakehurst.[5] Its 326-acre (132 ha) site at Kew has 40 historically important buildings; it became a UNESCO World Heritage Site in 2003.[6] The collections at Kew and Wakehurst include over 27,000 taxa of living plants,[7] 8.3 million plant and fungal herbarium specimens[8] and over 2.4 billion seeds collected from nearly 40,000 species in the Millennium Seed Bank.[9]
Mission
edit
The Royal Botanic Gardens, Kew states that its mission is to apply scientific discovery and research to fully develop the information about and potential uses of plants and fungi.[10]
A conference held in 1976 by the Royal Botanic Gardens, Kew was important as it established a co-ordinating body in order to determine which threatened plants are in cultivation and where they are located which played a role in plant conservation.[11]
More than 470 scientists work for the Royal Botanic Gardens, Kew.[13] The Director of Science is Alexandre Antonelli.[14] The Deputy Directors are Elizabeth Gardner, Paul Kersey and Monique Simmonds.[15]
The scientific staff at Kew maintain a variety of plant and fungal data and digital resources, including those listed below.[17]
Plants of the World Online
edit
Plants of the World Online is an online database launched in March 2017 as one of nine strategic outputs with the ultimate aim being "to enable users to access information on all the world's known seed-bearing plants by 2020". It links taxonomic data with images from the collection, to provide a single point of access with information on identification, distribution, traits, conservation, molecular phylogenies and uses.[18]
International Plant Names Index
edit
The International Plant Names Index (IPNI) includes information from the Index Kewensis, a project which began in the 19th century to provide an "Index to the Names and Authorities of all known flowering plants and their countries".[19] The Harvard University Herbaria and the Australian National Herbarium co-operate with Kew in the IPNI database, which was launched in its present form in 1999 to produce an authoritative source of information on botanical nomenclature including publication details of seed plants, ferns and lycophytes. It is a nomenclatural listing of all published taxonomic plant names including new species, new combinations and new names at rank of botanical family down to infraspecific. It provides data for other related projects including Tropicos and the Global Biodiversity Information Facility (GBIF).[20]
Neotropikey
edit
Nitropikey is an international project, based at Kew Gardens, on the flowering plants of the Neotropics (tropical South and Central America).[21][22][23]
World Checklist of Selected Plant Families
edit
The World Checklist of Selected Plant Families (WCSP) is a register of accepted scientific names and synonyms of 200 selected seed plant families. WCSP is widely used, and most authoritative web resources on plants use it as their basis.[24][20]
World Checklist of Vascular Plants
edit
The World Checklist of Vascular Plants (WCVP) includes all known vascular plant species (flowering plants, conifers, ferns, clubmosses, and firmosses). It is derived from the WCSP and the IPNI and therefore only includes names found in those databases. It is the taxonomic database for Plants of the World Online. Since WCSP includes only selected families, WCVP will seek to complete the process.[25][20][26]
World Checklist of Useful Plant Species
edit
The World Checklist of Useful Plant Species lists 40,292 species, including nine non-plant taxa (e.g. nostoc, forkweed, brown algae), compiled from multiple pre-existing datasets.[27][clarification needed]
Collaborative projects
edit
The Plant List
edit
Kew also cooperated with the Missouri Botanical Garden and other international bodies in The Plant List (TPL). Unlike the IPNI, it provides information on which names are currently accepted. The Plant List is an Internet encyclopedia project which was launched in 2010 to compile a comprehensive list of botanical nomenclature.[28] The Plant List has records for 1,064,035 scientific names for plant species, representing 350,699 accepted plant species. In addition, the list has records for 642 plant families and 17,020 plant genera. It was last updated in 2013, and was superseded by World Flora Online.[29][30]
World Flora Online
edit
World Flora Online was developed as a successor to The Plant List, in 2012, aiming to include all known plants by 2020.[30][31]
