Monitoring 2.2: BirdLife IBA Monitoring Framework
As well as implementation guidelines, The IBA monitoring framework provides a standardised way to assign scores to selected indicators for the status of IBA biodiversity (‘state’), threats (‘pressure’) and conservation actions (‘response’). Comparing scores between years gives an indication of trends.
In each case, a standard methodology is followed to assign scores to one of four levels (e.g. for threat, ‘low’, ‘medium’, ‘high’ or ‘very high’). Trend scores, representing changes between assessment, can thus range from -3 to +3.
The scoring system uses a ‘weakest link’ approach, applied to the species for which an IBA qualifies (its ‘trigger species’). Thus if trigger species differ in their status, the species in the worst situation provides the score for the site as a whole.
This approach allows clear and easily-understood presentation of the results, both site-by-site and between sites, in a similar way for each of Pressure, State and Response. Its simplicity is appropriate for a system that will often be based on qualitative data, and which aims to capture a valid general impression (rather than a precise measurement) of status and trend.
With only four levels, however, the step between each level is large. This makes the scores relatively insensitive to change. More detailed information is not lost but is captured through the methods for arriving at these overall ‘headline’ scores in the World Bird Database. The framework also guides the capture of specific information on particular responses, such as the presence and activities of Local Conservation Groups (LCGs).
