“…The PA complementarity network analysis takes into account taxa richness and ecogeographic diversity that may be used as a proxy for genetic diversity, which is required in the designation of a CWR genetic reserve (Greene & Hart, ; Parra‐Quijano et al ., ; Iriondo et al ., ; Parra‐Quijano et al ., ). For taxa with narrow distributions such as Poa lindebergii Tzvelev, 100% of ecogeographic diversity is conserved within the PA complementary network, whereas for a common species with a wide distribution such as Deschampsia flexuosa (L.) Trin, 59% of ecogeographic diversity is conserved.…”

Aim To contribute directly to Norway's national and international commitments to systematic, long‐term conservation of crop wild relatives (CWR) by ensuring both the in situ and ex situ protection and availability of a broad range of CWR genetic diversity within the country. Location Norway. Methods We created a priority list of CWR within Norway based upon four main criteria including economic value from national to global level of associated crops and inclusion in Annex 1 of the International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA). Species presence data were gathered from the Global Biodiversity Information Facility (GBIF) and used for predictive species distribution modelling in MaxEnt. capfitogen software was utilized to create an ecogeographic land characterization (ELC) map and to identify complementary in situ genetic reserves and ex situ collecting priorities which target the full range of ecogeographic diversity of taxa. Results An inventory of 204 priority CWR within Norway was compiled. A grid cell complementary network of 19 in situ areas (~10 km2) conserved 201 priority CWR, and a separate analysis identified a protected area complementary network of 23 reserves that conserved 181 priority taxa. For ex situ conservation, 177 taxa did not have ex situ accessions and of the 24 with accessions, 15 had the minimum of five populations conserved throughout their ecogeographic range. Main conclusions We present the first comprehensive national recommendations for in situ and ex situ conservation of 204 priority CWR in Norway. Proposals target the conservation of the ecogeographic diversity of the priority CWR and hence their genetic diversity. Both the priority taxa and the methodology used are applicable at regional and global scales with the recommendations not only helping Norway to meet its international obligations for conservation of genetic diversity of CWR but also ensuring this genetic diversity is available for use in tackling global food security.

“…To guarantee real in situ conservation, active conservation measures involving the establishment of genetic reserves are needed (Maxted and Kell, 2009;Iriondo et al, 2012). Detection of ecogeographical gaps in ex situ conservation (which is the basis of the present study) can be useful as a part of a strategy to outline future genetic reserves (Parra-Quijano et al, 2012a).…”

A Multispecies Collecting Strategy for Crop Wild Relatives Based on Complementary Areas with a High Density of Ecogeographical Gaps

Amidst the general concern about the need to conserve crop wild relatives (CWR) as a source of genetic diversity potentially useful in crop breeding, recent studies have assessed global gaps in CWR conservation using predictive distribution approaches. However, few options are available to downscale such studies and conduct efficient seed‐collecting expeditions in specific target areas for ex situ conservation. A new type of optimized collecting design (OCD) to determine priority areas for collecting CWR is presented to fit this purpose. The new approach is based on the principles of complementarity and ecogeographical representativeness of ex situ collections, using ecogeographical variation as a proxy for genetic diversity of adaptive value. It aims to offer a collecting strategy that captures the maximum genetic diversity of adaptive value at a minimum cost. Ninety‐eight priority species related to cereal and legume crops, selected by the Spanish National Strategy for CWR Conservation, were targeted to illustrate this approach. The analysis resulted in a ranking of 10‐ × 10‐km areas containing decreasing richness of complementary ecogeographical gaps of selected CWR taxa. The top 10 complementary areas were overlapped with the Spanish Sites of Community Importance of the Natura 2000 network to prioritize collection in areas not covered by the network, which would be more exposed to habitat destruction and other anthropic risks. This new kind of OCD allows collectors to efficiently sample nonrepresented populations of many species growing in adaptive scenarios within a relatively reduced area at the same time.
