Joint migratory bird monitoring programmes and support of common scientific and management projects to promote conservation and management of the natural resources of the Wadden Sea and Banc d’Arguin. The ambition is for the two sites to take lead in simultaneous counts along the entire East Atlantic Flyway in order to get a full picture on the status of migratory bird populations using the flyway. Research on migratory birds in the Wadden Sea and Banc d'Arguin is closely interconnected and significant for all other wintering, breeding and staging sites along the flyway. Thus, only scientific cooperation can reach a holistic perception of the flyway and a common basis for successful management.
