Wadden Sea Ecosystem 22: Breeding Birds in the Wadden Sea in 2001
Results of the total survey in 2001 and trends in numbers between 1991 - 2001.
With the publication of this report, it is the third time that a complete breeding bird survey of the entire Wadden Sea is presented in the framework of the Trilateral Monitoring and Assessment Program (TMAP) by the Joint Monitoring Group of Breeding Birds in the Wadden Sea (JMBB). The results of the first complete survey of breeding birds in the entire Wadden Sea, undertaken in 1990, were published in 1994 as the first issue; the results of the second complete survey of breeding birds in the Wadden Sea, carried out in 1996, were published in 2000 as the tenth issue of the publication series ‘Wadden Sea Ecosystems’ edited by the Common Wadden Sea Secretariat (CWSS).
The Wadden Sea Ecosystem No. 22 includes the results of the 2001 total survey and the comparisons to the first and second surveys, ten respectively five years ago. This report reflects the fact that the joint breeding birds monitoring program has been operational for a long period of time, allowing for the analysis of long-time series. The next total count, the fourth one, was carried out in 2006.
