Compilation of the CWR inventory

What is an inventory of CWR?

An inventory of CWR is the list of CWR taxa present in a defined geographic unit (region, country etc) with ancillary information, such as: nomenclature, the applied Gene Pool or Taxon Group concepts and actual and potential utilization of the CWR for crop improvement, biology, habitats, ecogeography, direct uses, threats and threat status, current conservation actions and legislation. An inventory is usually created after prioritization of the CWR checklist, for the priority taxa only (Maxted et al. 2013)1.

Alongside checklists, CWR inventories provide the essential foundations for the formulation of in situ and ex situ conservation strategies. CWR inventories usually include information on priority CWR relevant to conservation planning and they provide policy-makers, conservation practitioners, plant breeders and other user groups with a view of current CWR priorities. As CWR priorities change over time, so should CWR inventories.
