List of codes used in the World Geographical Scheme for Recording Plant Distributions

The World Geographical Scheme for Recording Plant Distributions (WGSRPD) is a biogeographical system developed by the international Biodiversity Information Standards (TDWG) organization, formerly the International Working Group on Taxonomic Databases. The system provides clear definitions and codes for recording plant distributions at four scales or levels, from "botanical continents" down to parts of large countries. Current users of the system include the International Union for Conservation of Nature (IUCN), and the Germplasm Resources Information Network (GRIN).^[1] Plants of the World Online uses Kew's data sources,^[2] and hence also uses the WGSRPD for distributions.
