Abstract
Crop Wild Relatives (CWR) are wild plants closely related to crop species that can contribute genetic material to them (Heywood et al., 2007). Their evolution in natural conditions provides them with genetic diversity that has been very valuable in plant breeding already. As wild plants, many of them are menaced by climate change and other threats to biodiversity (changes in land use, fragmentation, genetic pollution, etc.). According to Humphries et al., (1995), a sound conservation plan should take into account all components of biodiversity, including genetic diversity. In this communication, we show an approximation to fulfill this premise. We have created a new target for conservation (SpEcoU), which considers genetic diversity of adaptive value using ecogeographical land characterization maps as a proxy. The in situ conservation status of a list of prioritized Spanish CWR and Sp-EcoUs created from this list is assessed using the Natura 2000 network. Distribution data of 459 CWR species and 4726 Sp-EcoUs were overlaid with the N2000 network. Subsequently, an evaluation of the performance of the N2000 network in the in situ conservation of both targets was performed, checking how many species, Sp-EcoUs and populations for each target were covered by it. Additionally, a complementarity analysis using both 1x1 km cells and N2000 sites was made. Results show that 74% of the species and 9% of the Sp-EcoUs have at least five of their populations within the limits of the N2000 network. On the other hand, 20 cells (1x1 km) would be sufficient to preserve 68% of the species, and 20 cells encompass 32% of the Sp-EcoUs. When sites of the N2000 network were considered, 20 sites cover 74% of the species and 20 sites 53% of the Sp-EcoUs. These assessments are essential to efficiently distribute the resources for CWR in situ conservation and direct efforts to maximize the preservation of genetic diversity.
