These sites may contain threatened species, endemic species, species representative of a biome, or highly exceptional concentrations of birds. Sites are identified using a set of standardized and internationally agreed upon criteria that have gained worldwide recognition. IBAs are identified according to their significance (based on specific bird population thresholds) as either globally, continentally, or nationally significant.)

All sites identified as potential IBAs were subjected to rigorous review to determine whether they truly qualified. They represent sites which include both terrestrial and non-terrestrial habitats that are critically important for bird species not just during the breeding and wintering seasons but also during migration.)
