INTERACTIVE TOOLKIT FOR
CROP WILD RELATIVE CONSERVATION PLANNING version 1.0
An ecogeographic study comprises three main phases: project design, data collection/analysis and the ecogeographic products. The project design includes:
1. Identification of target taxa expertise.
2. Selection of target taxa taxonomy.
3. Delimitation of target area.
4. Design and creation of the database structure (optional).
The data collection and analysis phase includes:
5. Survey of occurrence data, as well as passport, site and environment, and existing characterization and evaluation data.
6. Collation of occurrence data into the database.
7. Data verification.
8. Data analysis.
The ecogeographic products include:
9. A CWR occurrence data database (which contains raw data).
10. A conspectus (that summarizes the taxonomic, geographical and ecological data for the target taxa).
11. A report (which interprets the data and results obtained).
1. Identification of taxa expertise
Taxon experts and experts in the flora of a target area may provide accurate species location and ecological information and may be able to recommend relevant grey literature, Floras, monographs, taxonomic databases, the appropriate herbaria and genebanks to visit. They could also put the conservationist in contact with other specialists. Experts to contact may include:
2. Selection of target taxa taxonomy
The most widely accepted taxonomic classification can be determined with the aid of:
It is important to detect existing synonyms to avoid missing specimens that may be identified under synonymous names and to prevent separate treatments of the same taxon. In the context of the development of a National Strategic Action Plan for CWR Conservation (NSAP) [1], this step would already have been undertaken as part of the creation of the CWR checklist.
3. Delimitation of the target area
Normally an ecogeographic study should include the whole range of a species’ distribution so as to avoid the problem of non-compatible datasets that can be inherent in multiple surveys of the same taxon. However, given that conservation planning included in a NSAP is undertaken at national level, the whole country should be the target area.
4. (Design and creation of the occurrence database structure)
This step is optional as the use of the existing Occurrence data collation template [2] is recommended (see step 6 for more details).
5. Survey of occurrence data
Sources of data are likely to include:
In addition, have a careful look at the recommendations listed in Annex A of Castañeda et al. (2011) [5], which aims to facilitate the recording of passport data.
Ideally, occurrence data should be available for every CWR included in the study, though it should be stressed that georeferencing is often required to ensure the necessary data is complete. The broader the sampling of occurrence data the more geographically and ecologically representative the data, and ultimately the results, will be.
6. Collation of occurrence data into database
The use of the existing Occurrence data collation template [2] is recommended. The template caters for different types of data (genebank accessions, herbarium specimens, bibliographic references, internet references, biodiversity or botanical databases (e.g. GBIF), personal communications from experts and field observations) and, if the data is to be used for ecogeographic diversity analyses, the template also helps the user to prepare the data for use in the CAPFITOGEN tools [6] (Parra-Quijano et al. 2016).
7. Data verification
8. Diversity analyses of collated occurrence data
Data analyses may include:
Like the hotspot analysis, the complementarity analysis can be undertaken at species, ecogeographic or genetic diversity level, but rather than using the species name as the unit, the binomial species-ecogeographic category should be used instead. This involves overlaying the species distribution onto the ELC map and extracting the ecogeographic category for each occurrence data point. Complementarity analysis can be carried out using the tool Complementa [12] from the CAPFITOGEN tool set [6] (Parra-Quijano et al. 2016) for both grid and protected area analysis, or DIVA-GIS [9] can be used for grid analysis only. More information on the establishment of genetic reserves to actively conserve CWR based on these analyses is provided here [15].
9. Data synthesis
After the data has been collated and analyzed, the following products should be produced: an occurrence database (which contains raw data after verification and standardization), an (optional) conspectus (which summarizes all of the data collated for each CWR) and a final report (which interprets the data obtained and is usually a part of a conservation planning report or a CWR National Strategic Action Plan/National Strategy).
1 Environmental Impact Assessment (EIA) have been defined by the IAIA and IEA (1999) as “the process of identifying, predicting, evaluating and mitigating the biophysical, social, and other relevant effects of development proposals prior to major decisions being taken and commitments made.” In other words, they permit assessing the possible negative and positive impacts that a project (e.g. highway, dam, building, etc.) may have on the natural, social and economic aspects. Regarding the biophysical aspect, EIA reports generally provide species lists of Flora (and Fauna) that occur in the area where the project is to be developed thus constituting important sources of species distributional data.
