TAXONOMIC INFORMATION IN GRIN


ECONOMIC IMPORTANCE

Currently 32,047 economic impact records exist in GRIN for the 18,683 taxa for which economic plant data are provided. GRIN economic data are classified to two levels adapted from the Economic Botany Data Collection Standard (Cook, 1995). A total of 16 classes are recognized, including 13 from this Standard: food, food additives, animal food, bee plants, invertebrate food, materials, fuels, social uses, vertebrate poisons, non-vertebrate poisons, medicines, environmental uses, and gene sources, with the addition of classes for weeds, harmful organism hosts, and CITES-regulated plants. Note that two of these added categories plus vertebrate poisons do not represent beneficial uses, but are mostly negative in their economic impact. The 16 classes are further subdivided into 113 subclasses. Sources of economic data are referenced in GRIN. A thorough discussion of GRIN economic data can be found at World Economic Plants: A Standard Reference.
