Description: Effective seabird conservation requires management of key locations for nesting, foraging, and migration. The identification of critical marine bird colonies and pelagic concentration areas has a varied history with many definitions applied. Important Bird Areas (IBAs) are based on an established program that uses standardized criteria to identify essential habitats, which are areas that hold a significant proportion of the population of one or more bird species. BirdLife International, in partnership with the National Audubon Society, developed standardized criteria defining Important Bird Areas, establishing a global “currency” for bird conservation. To qualify as a globally significant IBA, a proposed site must hold a significant number of a globally threatened species, or a significant percentage of a global population, as evidenced by documented, repeated observation of substantial congregations in an area.
Some of these sites are listed as 'potentially global,' until the national review committee has an opportunity to officially designate these as global. Note also that the site profiles and reports that the file attributes link to are out of date. Both of these items will be updated later in 2015.
File includes intermediate results of new IBA analysis (including new pelagic, coastal, and interior IBAs), with preliminary single-species core area polygons, which were later dissolved together and cleaned up to produce the final IBA boundaries. Core area polygons are areas meeting the threshold for global significance for an individual species.
