In the menu on the right are indicated the most important wetlands along the flyway of the satellite-marked Purple Herons that migrate between the Netherlands and Africa to complete their annual migration cycle. Click on the names of the wetlands to visit the pages for more details on the site.

A new tool for the identification of important sites Critical Site Network Tool is still under development under the Wings Over Wetlands (also known as the UNEP-GEF African Eurasian Flyway) Project. It aims to support site managers, national authorities and international organisations to obtain information about the critical sites for waterbird species in the African-Eurasian region.
