Annual report of the Seabird Monitoring Programme
Seabird Population Trends and Causes of Change: 1986–2023
This report presents the latest seabird population trends in breeding abundance and productivity using data from the Seabird Monitoring Programme (SMP).
The report documents changes in the abundance and productivity of breeding seabird species in Britain and Ireland from 1986 to 2023, and provides a detailed account of the 2021, 2022 and 2023 breeding seasons.

Several studies have documented population declines in species of waterbird that winter on The Wash SPA and are protected as non-breeding features. With a few exceptions, the reasons for these declines are not clear cut.This project brought together findings from a wide range of studies to the identify drivers of population change on The Wash, where possible, for 15 species, and to make recommendations about measures that could be taken to halt or reverse these trends.
