The IBA identification process provides a data-driven means for cataloging Washington’s most important sites for birds, using a set of standardized criteria recognized worldwide.

An Important Bird Area is a site providing essential habitat for one or more native species of birds in Washington at any time in their annual life cycle. Sites vary in size, and are usually distinguishable from surrounding areas in character, habitat, or ornithological importance. In most cases, sites are delineated by clearly recognizable physical features that separate them from adjacent areas.

In general, IBAs are predominantly natural areas. Human-made habitats that attract birds, such as landfills and sewage lagoons, are generally not eligible for IBA status. Further, there should be reasonable potential for IBAs to receive additional protection and/or enhanced habitat management in the future for the benefit of birds.

The criteria are divided into three major categories at three geographic scales. Sites meeting one or more of these criteria may qualify as Important Bird Areas at the state, continental, or global scale.
