The World Database of Key Biodiversity Areas is managed by BirdLife International on behalf of the KBA Partnership. It hosts data on global and regional Key Biodiversity Areas (KBAs), including Important Bird and Biodiversity Areas identified by the BirdLife International Partnership, Alliance for Zero Extinction sites, KBAs identified through hotspot ecosystem profiles supported by the Critical Ecosystem Partnership Fund, and a small number of other KBAs. The database was developed from the World Bird and Biodiversity Database (WBDB) managed by BirdLife International.
