ECONOMIC BOTANY STANDARDS for CROP WILD RELATIVES Presentation for PGR Forum Workshop 5 8 September 2004 Terceira prepared by Maria Scholten, Shelagh Kell, Nigel Maxted and Brian Ford-Lloyd
2
ECONOMIC BOTANY STANDARDS for CROP WILD RELATIVES - Outline - View some economic botany databases from the perspective of crop wild relatives Compare use classifications TDWG as proposed standard? Recommend use standards for PGR Forum
3
1. Cereals, legumes (starch/sugar) 2. Fruits 3. Vegetables 4. Oil plants 5. Dyes, resin etc 6. Fibre 7. Wood 8. Animal food 9. Medicinal /poisons 10. Ornamental (11. Narcotic/stimulating) EXAMPLES OF EARLY USE CLASSIFICATIONS: Hegi 1931, Zhukovsky 1964, Schlosser et al. 1991

ECONOMIC BOTANY DATA COLLECTION STANDARD “TDWG” ( Cook 1995) Example 1: Carrot (Daucus carota L.) Level 1Level 2 Level 3 1313 8+20+24 Food additives Roots Specific Plant parts used (8 descriptors): roots Food additive types (20 descriptors) : colourings Preparations used in (24 descriptors): ice cream Example 2: Hierochloe odorata (L.) P.Beauv. Level 1Level 2Level 3 134 83+20 Social uses‘Religious’ UsesPlant part used (83 descriptors): entire Specific Social use types (20 descriptors): ritual/religion/magic

APPLICATIONS OF TDWG Database / publicationExtent of use New York Botanical Gardenslevel 3 partly MEDUSAlevel 1 - level 2 adapted FAO (Plantinfo and Ecocrop)level 1 FLORA CELTICA (RBGE)modified levels 1 and 2 SEPASAL (RBGK)completely ILDIS LegumesWeblevel 1 only Wild useful plants of Russiacompletely USDA (Wiersema)level 1 and 2 only Sources: TDWG Economic Botany Subgroup Report Summary 1999 MEDUSA: Chris Johnson personal communication

TWO TYPES OF USE STANDARDS: 1. Economic botany (TDWG prevalent) 2. Use in the context of Red Listing DATABASES TO BE COMPARED: World: GRIN - world - crops and first gene pool relatives MWD - world - crops and wild relatives Specific or regional: SEPASAL - semi-arid and arid areas - wild and semi-domesticated MEDUSA - Mediterranean - wild (potentially) useful plants ILDIS - world - legumes Russian CWR database - European crop wild relatives

GRIN: 16 gene source subcategories Query: Genetic Uses = 'all subclasses’ 760 hits Query: Genetic Uses = 'for crop progenitor’ 43 hits Query: Genetic uses = ‘for ornamental cultivars’ 267 hits Query: Genetic Uses = 'for crop relative’ 186 hits

IUCN utilization authority file (version 1.0): 1. Scale of usage: proportion of total (global) population in use 2. Purpose of use: subsistence / national /international: 16 use categories 3. Forms removed from the wild: whole/parts 4. Source of specimen in commercial trade (in %) wild or other 5. Trends in offtake or harvest (increase /stable / decrease) 6. CITES status (Appendix I, II or III or not listed)
