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.

A review of the Biological Defined Minimum Population Scale (BDMPS) approach and methodology to apportioning non-breeding season impacts on seabirds arising from offshore wind farms

Author:

Published: 2025

Estimates of breeding seabird populations are used to assess the potential impacts of proposed wind farm developments. The approach used in these assessments is known as the Biologically Defined Minimum Population Scales (BDMPS) method, and it was developed by Furness in 2015. This report evaluates the methods developed by Furness, and highlights potential refinements to the current BDPMS approach, including methods, definitions, and data resources, to improve future ease of use and accuracy of estimates.
