However, many of the protected waterbird species at Lakes IJsselmeer and Markermeer are migratory. This poses extra challenges when the interpretating detected trends. Population declines may be caused by many different factors, either within the IJsselmeer/Markermeer itself, or elsewhere within the East Atlantic Flyway. This report analyses population trends of important waterbird species of Lakes IJsselmeer and Markermeer at the local and flyway level, and addresses the differences and similarities found.
