JARDIM BOTÂNICO – MUSEU NACIONAL DE HISTÓRIA NATURAL (PORTUGAL) Setting conservation priorities for Crop Wild Relatives in Portugal Joana Magos Brehm Brian Ford-Lloyd Nigel Maxted Amélia Loução
Contents • Brief introduction • Objectives • Methodology • Results • Advantages and constraints • Problems encountered • Conclusions • References • Acknowledgments
Objectives • To compare different methods of prioritising CWRs at a country level. • To be an aid in the establishment of conservation priorities within CWRs for Portugal.
Brief introduction Portugal... • ~ 3000 native sp. (mainland) (Ministry of Agriculture, 1995). • Wealth of CWRs and other wild species with immediate or potential economic interest (as agricultural, ornamental, forage, aromatic and medicinal plants).
Brief introduction Major methods for prioritising Genetic Resources/Biodiversity • Point scoring procedure • MER (2000) – risk of extinction of wildlife • Sapir et al. (2003) – red numbers for endangered plant species in Israel (rarity, declining rate and habitat vulnerability, attractivity, distribution type) • Dhar et al. (2000) – medicinal plants in the Indian Himalaya region (use value index, sensitivity index, importance value index) • Millsap et al. (1990) – assess conservation status of vertebrates • Lunney et al. (1996) – point scoring procedure with weighting (mammals, birds, reptiles and amphibians in New South Wales, Australia)
Brief introduction Major methods for prioritising Genetic Resources/Biodiversity • Ranking system • NatureServe (2001) – conservation actions or any taxonomic entity, North America • Pashley et al. (2004) – birds, North America • Rule-based system • IUCN (2001) – threat criteria and categories • CITES (www.cites.org)
Methodology • Database building and Criteria • Point Scoring Procedure (PSP) • Point Scoring Procedure with Weighting (PSPW) • Simple Ranking System (SRS) • Compound Ranking System (CRS)
Methodology 1. Database building and Criteria • Starting point: PGR Forum list of CWRs for Portugal (Mansfeld’s and Euro+Med database) • Adopted taxonomy: Iberian Flora (Talavera et al., 1999-2000) National Flora (Franco, 1971-2003) • Synonyms: Iberian Flora (Talavera et al., 1999-2000) National Floras (Franco, 1971-2003; Coutinho, 1939) Flora Andaluccía (Valdés et al., 1987) Flora Europaea (Tutin et al., 1964-1988)
Ethnobotanical Value • National uses (wild harvested species) • Red Listing assessment (IUCN, 2001, 2003) Threatened status Methodology 1.Database construction and Criteria Economic Importance • Crop category • Production of related crop (€) • Production of related crop (tons) • Surface of cultivation (ha) • Traditional products • # grown varieties Genus level Actual Economic Value Species level • Potential uses Potential Economic Value
Conservation status • Ex situ • In situ (active) • Habitat’s Directive (92/43/EEC) • Bern Convention (Appendix 1) • Euro Council (1977/1983, 1983) • Other international legislation • National legislation Legislation Global Distribution • Portugal; Iberian Peninsula; Iberian Peninsula+North Africa; Mediterranean; Europe/World National distribution • # provinces Methodology 1.Database construction and Criteria Species level
National statistics (INE, Portugal) • FAO Stats • National Catalogue of Varieties • Iberian Flora • Flora Europaea • Iberian Flora • EURISCO • Aguiar et al. (2001) • Mitchell (2004) • General ethnobotanical literature on uses • National ethnobotanical literature on uses • ICN (Natura 2000 Network) • EUFORGEN • Legal documents

Problems encountered General problems: • Taxonomy • Time consuming • Quality of data • Unavailability of data: • economic data and threat assessment • ornamental and forestry species Inaccurate results for those species without a complete set of data
not included in any economical statistics Problems encountered Specific questions: • Ethnobotanical data (national uses): Economic value? Cultural value? • When different uses of the related crop, should we consider the most nationally economic important use or the use with high score? e. g. Pinus pinea – food and agriculture (pine nut) (7) or forestry (4)? • Medicinal and aromatic plants known to be small scale cultivated and marketed • Are the criteria used enough? • Population biology data? Demographic data? Ecological data? Genetic diversity? Genetic erosion and pollution? Recent and potential threats? Climate change?
Different methods different results • Different country’s needs / users’ needs choose the criteria and the method that suits best • The criteria used in setting conservation priorities tend to differ with the user; any RS is better than the PSP methods because is more adaptable to the users’ needs. • CRS, levels 1 and 4, is simpler than using the other levels and seems to give good results although using Y/N criteria. • Whatever the method, priorities must be viewed as a working hypotheses based on the best available information.
