An Important Bird Area (IBA) is an area designated as globally important habitat for the conservation of bird populations.

IBAs are determined by an internationally-agreed set of criteria. To be listed as an IBA, a site must satisfy at least one of the following conditions:

• provide habitat to sustain a population of an internationally threatened species.
• house large numbers or concentrations of migratory birds, shorebirds, or seabirds.
• be part of a large number of range-restricted or biome-restricted species.

Generally, IBAs must be amenable to conservation and wildlife management as well.

Currently there are about 7,500 IBAs worldwide.

The program was developed by BirdLife International; IBAs in a given country are designated by a national conservation organization.
