IBAs are monitored using a simple, practical and robust framework. This involves regular assessments in which each IBA is scored against indicators of pressure (the threat facing the site), state (the condition of birds and their habitats) and response (the actions being taken to conserve the site). To learn more about this process click here.
IBA monitoring is now well established in many countries; however, it is not yet systematically applied at all sites globally (e.g. in countries without a BirdLife Partner). If no data are displayed below then national IBA monitoring has yet to commence or the data have yet to be entered into the BirdLife World Database. In order to avoid providing potentially misleading information, no data are displayed unless at least 5% of sites in the country, or a total of 20 sites (whichever is smaller) have complete monitoring assessments.
This information is based on the most recent site assessments, dates of which may differ between sites.
'Trigger' (or qualifying) bird species are those for which a site has been recognised as an IBA under any of the global (or, where appropriate, regional or sub-regional) criteria. For a full explaination of the process of IBA identification click here

Trends over time in Pressure, State and Response at IBAs
This information is based on both complete and partial site assessments (i.e. those with
scores for one or two, but not all three, of state, pressure and response in a particular
nr. fav. = near favourable; unfav. = unfavourable; v. unfav. = very unfavourable. Grey bars indicate sample sizes, i.e. the number of complete site assessments per year.
Trends should be interpreted with caution because: (a) the number and subset of IBAs assessed may vary between years; (b) the number of parameters (Pressure, State, Response) for which each site is assessed may vary within and between years; and (c) the overall sample sizes may represent a small proportion, and potentially an unrepresentative subset, of all IBAs, particularly in some years. As more data are added into the BirdLife database, the trends will become more robust and reliable.
