Ecosystem 23: Seriously Declining Trends in Migratory Waterbirds

Causes - Concerns - Consequences

Proceedings of the International Workshop on 31 August 2006 in Wilhelmshaven, Germany.

Since the beginning of the eighties, water birds have been monitored in the entire Wadden Sea, in a close spatial and temporal pattern, mostly by hundreds of voluntary counters. Only this long-term and successful way of monitoring has facilitated the identification of development trends. The evaluation of the data gathered in the period from 1980 to 2000, in the framework of the Trilateral Monitoring and Assessment Program (TMAP) between Denmark, Germany and The Netherlands, which has been coordinated by the Common Wadden Sea Secretariat, had alerted the scientists and was the cause for the workshop held in Wilhelmshaven.
