In the 2000s a lot of progress has been made with regard to data storage and data analysis, allowing a meaningful analysis and comparison of trends in the various regions of the Wadden Sea. Apart from many trends being negative, some of the trends show remarkable differences between countries. For instance, bar-tailed godwit increases in the Netherlands, shows a stable development in Lower Saxony, but decreases in Schleswig-Holstein and Denmark. Similarly, dunlin increases in the Netherlands, shows a stable development in Lower Saxony and Denmark, but decreases in Schleswig-Holstein.
