The KBA Standard is formally taken to include definitions, the criteria and thresholds, and delineation procedures. It can be used by national constituencies to identify sites contributing significantly to the global persistence of biodiversity in terrestrial, inland water and marine environments. It is important that this Standard remains stable for a period of time to enable comparisons of sites qualifying as KBAs in different regions and over time. It is recognised, however, that the criteria and thresholds may need revision in the future as experience accumulates in their application and technological advances improve our measurement and understanding of biodiversity.
