3 CWR CONSERVATION PLANNING SUMMARY 1. Generation of CWR checklist (which CWR exist in?) Excel, Access 2. Selection of priority crop gene pools (which CWR are more important to conserve?) 3. Diversity and gap analysis (and climate change analysis) to select target sites for conservation (where are priority taxa located and are there gaps in their conservation?) DIVA-GIS / ArcGIS, MaxEnt, CAPFITOGEN 4. Recommendations for in situ / ex situ conservation action (where should we actively conserve priority taxa in situ and where should we collect for ex situ conservation?) 5. (Implementation of in situ / ex situ conservation action within and outside existing PA)

4 CONTENT What is gap analysis? Levels of gap analysis Individual CWR taxon gap analysis Ecogeographic diversity gap analysis

5 WHAT IS GAP ANALYSIS? A conservation evaluation technique that assists the prioritization of biodiversity elements for conservation action by identifying gaps in the conservation of those elements Compares natural patterns of diversity with the diversity that is already conserved, and identifies gaps in the biodiversity elements where natural diversity is not actively conserved, either in situ (in situ gap analysis) or ex situ (ex situ gap analysis)

6 LEVELS OF GAP ANALYSIS Depends on the objective of the study as well as on the type of data available Individual CWR taxon GAPS = taxa not conserved Ecogeographic diversity level (PROXY for genetic diversity) GAPS = ecogeographically diverse populations not conserved In situ Ex situ Genetic/trait diversity level GAPS = genetically diverse populations /populations that present a particular trait not conserved Distribution gap analysis (GAPS = areas where species has been predicted to occur but hasn t been observed)

7 INDIVIDUAL CWR TAXON GAP ANALYSIS Species level Compare priority CWR with taxa conserved in situ: GAPS = species that do not occur within PAs GAPS = species that do occur within PAs but are not actively conserved Compare priority CWR with taxa conserved ex situ in gene banks: GAPS = species not conserved ex situ Not conserved ex situ! (Jordan) Excel, Access

8 ECOGEOGRAPHIC DIVERSITY GAP ANALYSIS DIVA-GIS / ArcGIS, CAPFITOGEN Intra-specific level Compare complete range of ecogeographic diversity with that already conserved (in situ/ex situ) GAPS = ecogeographic units not actively conserved in situ/ex situ Create species Ecogeographic Land Characterization (ELC) map - climatic, edaphic, geophysic variables that best reflect potential adaptive scenarios for the species Overlap taxon distribution with ELC map Detect those ecogeographic categories not conserved in situ/ex situ conservation recommendations
