Selection and prioritization

By assessing the status and the nature of threats it is possible to focus conservation actions on selected target species, populations or areas. This will help keeping costs and management resources down to a minimum.

This module aims to provide guidance in how to identify and prioritize CWR species/populations and areas for targeted, in situ conservation interventions.




The process of selecting priority CWR species

There is no precise or agreed methodology for selecting species or populations for in situ conservation. Often, the selection is influenced by local requirements and circumstances, as well as the priorities of the agency responsible for implementing activities.

The questions below may be used to prioritize species for conservation based on their scientific, social, economic and cultural values.

Groups of criteria for priority setting

These criteria reflect variables contributing to a species’ status in terms of genetic value in relation to its cultivated relatives. Values can be assigned to each of the criteria to determine which are of most importance.

Conservation status

Looking at the situation of CWR and the degree to which they are threatened is often referred to as determining their conservation status or assessment. The process involves a species’ distribution and range, population size, genetic variation, habitat availability, ecosystem health and any threats to its survival in the short-, medium- and long- term.

The international union for conservation of nature (IUCN) Red List Programme is the most commonly used system for assigning species conservation status; it is intended to focus on national and local, rather than international conservation actions.

IUCN categories of threat include:
