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.

Bailiwick Bat Survey 2022 Report
Author: Newson, S.E., Allez, S.L., Coule, E.K., Guille, A.W., Henney, J.M., Higgins, L., McLellan, G.D., Simmons, M.C., Sweet, E., Whitelegg, D. & Atkinson, P.W.

This report presents the main findings from survey work delivered using passive acoustic monitoring devices deployed across the Bailiwick of Guernsey. Through the surveys that we support we aim to improve knowledge and understanding of species distribution and activity, covering a range of taxonomic groups, including bats, small terrestrial mammals and insects. Through this approach we provide robust datasets that can be used to inform better decision-making processes.

Declines in invertebrates and birds – could they be linked by climate change?
Author: Pearce-Higgins, J.W. & Morris, R.K.A.
Published: 2023
The long-term declines evident in many bird and invertebrate species have their origins within a suite of potential drivers, one of which is climate change. As well as impacting bird species directly, could climate change be increasingly hitting bird populations through its impacts on their invertebrate prey?
