CROP WILD RELATIVE CONSERVATION PLANNING version 1.0
The establishment and implementation of in situ conservation goals for national CWR diversity involve 12 steps:
1. Review in situ conservation gaps
In situ conservation gaps at individual taxon, ecogeographic, genetic and trait levels [1] should be reviewed in order to establish priorities for in situ conservation.
2. Combine in situ conservation gaps with the results of the diversity analyses
Diversity analyses include hotspots and complementarity analyses at individual taxon, ecogeographic and genetic diversity levels (for information on individual and ecogeographic diversity analyses, click here [2] for information on individual taxon and ecogeographic diversity analyses and here [3] for genetic diversity analyses). In situ conservation gaps and the results obtained in the diversity analyses should be integrated into the national in situ CWR network of genetic reserves and informal CWR management sites to conserve priority CWR diversity.
3. Incorporate climate change analyses into site selection
If you have undertaken a study on how climate change may impact the distribution of priority CWR, then you should take that into account when selecting sites for active in situ conservation. The rationale lies in the fact that in situ conservation sites should be established and implemented in areas where CWR populations will not be affected negatively by climate change (or the negative impact is minimal) so as to ensure their persistence in the wild and within the genetic reserves (Magos Brehm et al. 2016).
4. Select preliminary in situ CWR conservation sites for target CWR
The in situ conservation network is likely to result from the combination of in situ conservation gaps, diversity analyses (hotspot, complementarity etc.) and climate change analysis.
5. Integrate in situ conservation priorities with national/international agri-environmental schemes
The selected preliminary sites that constitute a national network of genetic reserves and informal CWR management sites should be integrated with agro-environmental schemes (e.g. those funded by the European Commission or other regional agencies) so that their management is nationally coordinated and regionally integrated. Encouragingly, there is a growing effort to strengthen the relationship between agriculture and the provision of ecosystem services (FAO 2010). Activities that promote the in situ conservation of PGRFA are now being set up as a result of Payment for Environmental Services (PES) schemes in an attempt to encourage and reward local communities for their role in conserving and managing PGRFA for the future. However, the actual implementation of these schemes remains a significant challenge in many countries. National Strategic Action Plans (NSAP) for the conservation and sustainable utilization of CWR [5] should also be integrated into national programmes, through the appropriate national focal point(s), for the implementation of the CBD [6], National Biodiversity Strategies and Action Plans (NBSAPs) [7], the ITPGRFA [8] (ITPGRFA 2001) and the Global Strategy for Plant Conservation (GSPC) [9]. Whether CWR are conserved in situ within PAs or outside of them, it is advisable that the sites have some form of legal protection to help prevent sudden threats to conserved populations (e.g. through a dramatic change in land use).
6. Ground truth of preliminary sites to determine whether sites are suitable for in situ conservation of target CWR
The sites must be ‘ground truthed’ in order to check whether they are suitable for long-term conservation of the target CWR. Various reasons may exist why even the highest priority potential sites may be unsuitable in practice:
7. Reformulate in situ conservation priorities (if necessary)
The ordered list of potential in situ conservation sites produced as part of the preliminary selection is the initial step towards the final list of sites. If the highest priority potential sites are unsuitable, sites further down the ordered list would need to be considered. The process of selecting in situ sites is pragmatic and iterative. It continues until a list of suitable sites can be agreed for implemention of conservation action, either in a genetic reserve or informal CWR management site. It should, however, be highlighted that if for some reason there are no suitable sites for the in situ conservation of priority CWR taxa or a population of particular interest, then the ex situ conservation of those taxa/populations must be carried out.
8. Select final in situ CWR conservation sites for target CWR
The final selection of in situ conservation sites results from screening the preliminary selection using information gathered during the site visit. Pragmatically, priority should be assigned to the sites containing suitable habitats that are not predicted to be altered significantly in the medium to long term. A well balanced set of in situ conservation sites may contain a mix of: (i) genetic reserves established in existing PA, (ii) informal CWR management sites, (iii) sites in areas where PA boundaries have been extended, and (iv) sites established as novel PA. Together, each of these will form the National In Situ CWR Conservation Network that should be managed as a coherent whole. It should be emphasized that ultimately, the final selection of sites—although a pragmatic decision directed by science—is dictated by the resources available for in situ conservation and the governmental policy context at both the national and local levels.
9. Ensure the sites (genetic reserves) comply at least with the minimum quality standards
The quality standards for in situ CWR conservation sites (Iriondo et al. 2012) provide useful guidance for both the practitioners involved in the design of in situ conservation strategies for CWR and the PA managers interested in their conservation. The standards have two levels: ‘minimum’ and ‘optimal’ quality standards. The minimum quality standards are baseline requirements necessary for any genetic reserve to function and fulfil its conservation objectives, whereas optimal quality standards include a more rigorous set of requirements. Quality standards can be applied to: (a) the genetic reserves themselves, and include traits such as location, spatial structure, target taxa, populations and management, (b) the PAs selected for the establishment of genetic reserves and (c) informal in situ conservation areas outside of formal PAs.
10. Ensure communities are involved in local CWR diversity conservation and management
Promoting the involvement of local communities in in situ conservation and management of CWR is often crucial for conservation to be effective, especially when in situ conservation sites are located on private land. Local community training workshops can be carried out and agreements with private owners (e.g. tax incentives) can be made. However, agreements must be linked to some form of guarantee from the land owner to ensure CWR diversity thrives. For example, establishment of a management agreement including a conservation prescription in order to ensure CWR are properly managed, but also to recognize the local communities’ role in conserving such a valuable resource. For examples on the integration of conservation into local communities and industry, click here [11].
11. Produce in situ site and CWR taxa conservation action/management plans
The first step in formulating a CWR management plan, or amending an existing management plan to include CWR, is to observe the biotic and abiotic dynamics of the site considering both CWR and non-CWR species. A survey of the species present in the site should be carried out to help understand the ecological interactions within the reserve. A clear conservation goal should be decided and a means of implementation agreed. This process may involve some compromise between the priorities for CWR and non-CWR species conservation. This then forms the basis of the site action/managements plans, which will contain information on: CWR taxonomy, description, image, distribution, ecogeography, current conservation status and actions, threat assessment, uses, additional conservation actions required, research and monitoring requirements, incorporation into existing national or local conservation initiatives and, perhaps most importantly, it summarizes the management interventions recommended for the site and how the CWR are to be monitored to ensure the management is promoting CWR population health (Maxted et al. 2008b). As part of the routine site management, a monitoring regime that results in collection time series data of target CWR’ populations should be implemented with the aim of facilitating future reviews of project interventions (for more information, click here [12]).
12. Establish routine collection of CWR diversity for ex situ conservation back-up
CWR diversity within the National In Situ CWR Conservation Network should be backed up ex situ as an insurance in case there is a reduction of genetic diversity in CWR populations or in case they go extinct (Maxted et al. 2008b).
