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.

Bat distribution and activity in the Skell Valley catchment, 2024 Report

Author: Newson, S.E. & Crisp, G.

Published: 2025

This report presents the main findings from survey work delivered using passive acoustic monitoring devices deployed across the Skell Valley catchment. 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 birds, bats, small terrestrial mammals and insects. Through the approach we provide robust datasets that can be used to inform better decision-making processes.

The Białowieża Forest as an example of the resilience of long-term studies in a changing world

Author: Broughton, R.K., Cholewa, M., Czeszczewik, D., Fuller, R.J., Jaroszewicz, B., Kuijper, D.P.J., Maziarz, M., Mikusiński, G. & Neubauer, G.

Published: 2025

Long-term studies offer valuable ecological insights but are vulnerable to change. Environmental, social and geopolitical changes bring risks and opportunities. Poland's Białowieża Forest has seen decades of changes and provides lessons of research resilience. Collaborative teams and leadership dispersed between institutes disperses the risk, and adaptability in exploiting opportunities aids the continuity of long-term studies.
