The Irish Wetland Bird Survey (I-WeBS) has been gathering data on wetland birds in Ireland since 1994. This report details the trends of species nationally and at various sites based on the data gathered in the seasons 1994/95 through 2019/20.
Sites and species are only included in the reports if sufficient high-quality count data has been gathered.
For guidance on how to interpret these trends, please see the I-WeBS Trends Report Guidance.
For details on the methods used to generate these trends, please see the I-WeBS Trends Report Methodology.
Site-specific trend reports are available for the following sites:
