  1. CWR prioritization at national level: case studies and lessons learnt Joana Magos Brehm, Shelagh Kell, Nigel Maxted,Brian V. Ford-Lloyd, Maria Amélia Martins-Loução Joint PGR Secure/ECPGR workshop: Conservation strategies for European CWR and LR diversity 7–9 September 2011, Palanga, Lithuania

  2. Overview • Introduction • United Kingdom • Portugal • Lessons learnt

  3. Introduction • Broad CWR definition with generic limit = relative large number of taxa • Limited financial and human resources How to do it? Which criteria to use? Which method to use?

  4. CWR Inventory UNITED KINGDOM European and Mediterranean Catalogue of CWR (Kell et al.2005) Country filter UK CWR

  5. CWR Prioritization UNITED KINGDOM • 2300 plant species • 1863 CWR (81% UK Flora) (Maxtedet al. 2007) • 300 food and agriculture CWR species • 850 ornamental CWR species • 80 threatened CWR species (IUCN categories: CR, EN, VU)

  6. CWR Prioritization UNITED KINGDOM • Economic value • Crops listed in DEFRA’s home production statistics • Seed Traders National Annual Return (forage/fodder crops) • EU Common Catalogue of Agricultural and Horticultural crops genera • Genera in International Union for the Protection of New Varieties of Plants (UPOV) • Ornamental species with more than 100 nursery suppliers (in 2004) • Threatened status • Red List (80 threatened CWR) (Cheffingset al. 2005) 250 PRIORITY CWR (Maxtedet al. 2007)

  7. PORTUGAL CWR inventory European and Mediterranean Catalogue of CWR (Kell et al.2005) Country filter Flora Iberica/ Flora de Portugal Taxonomic harmonisation Portuguese CWR Ethnobotanical uses Global distribution Ex situconservation Nationaldistribution Economic value Threatened status In situ conservation Legislation PORTUGUESE CWR INVENTORY Internet www.jb.ul.pt (MagosBrehmet al. 2008)

  8. PORTUGAL CWR inventory • 2262 CWR (mainland) (~68% Portuguese Flora) • Leguminosae, Compositae, Poaceae – higher number of CWR • 141 Portuguese endemics and 253 Iberian endemics • ~12% ex situ conservation • <1% in situ conservation • ~14% threatened spp. Magos Brehm et al. 2008

  9. Economic value Ex situ conservation In situ conservation Global distribution Threatened category National distribution Legislation PORTUGAL CWR prioritization Native status 20 priorities 2262 CWR Inventory Prioritisation at species level - 8 criteria, 4 methods- Priority species (Magos Brehm et al. 2010)

  10. PORTUGAL CWR prioritization • Prioritising – different methods • Point Scoring Procedure • Point Scoring Procedure with Weighting • (Simple Ranking System) • Compound Ranking System • Binomial Ranking System (Magos Brehm et al. 2010)

  11. PORTUGAL Point scoring procedure Σ(Economic Value + Threatened Status + Conservation status + Legislation + Global Distribution + National distribution) Highest scores - priorities for conservation

  12. 15 % 20 % 15 % 15 % 15 % 10 % 10 % Habitat’s Directive Other international legislation Bern Convention National legislation Euro Council Legislation PORTUGAL Point scoring procedure with weighting Conservation status Economicvalue Threatened Status Native status Ex situ In situ (active) Highest scores - priorities for conservation Global distribution Nationaldistribution

  13. Compound Ranking System Binomial Ranking System Simple Ranking System Level 2 Level 1 Level 4

  14. Species occurring in ≥ 4 methods Global distribution • 50 top species Point scoring procedure (PSP) Point scoring procedure with weighing (PSP) Compound ranking system (CRS1, CRS2, CR3) Binomial ranking system (BRS1, BRS2, BRS3) Ex situ conservation Economic value National distribution Threatened status In situ conservation Legislation PORTUGAL CWR prioritization PORTUGUESE CWR INVENTORY Native status 20 Priority CWR Species (Magos Brehm et al. 2010)

  15. PORTUGAL CWR prioritization Matrix of overlapping % between methods and between the final list of priority CWR (by combining the different methods) and the result obtained with each method (Magos Brehm et al. 2010)

  16. Lessons learnt • The criteriaand the method used in setting conservation priorities tend to differ with the user, country, etc. • A single criterionor the use of different methods change greatly the results • Relatively low level of similarity between individual results and the final list obtained by combining all methods (high degree of subjectivity associated with the use of a single method) • Need to reduce subjectivity in order to obtain reliable results: combination of methods • Whatever the criteria and the method, priorities must be viewed as a working hypotheses based on the best available information.
