Description

This report summarises trends and numbers of coastal breeding birds in the transboundary Wadden Sea. It is an update of the last report from 2020, adding another six years to the existing data series. Hence, we can report on long-term trends in changes in abundance (since 1991, i.e. 33 years) and short-term trends for the last twelve years (2012-2023).
