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.

Published: 2020
A newly published assessment of the evidence that climate change is causing biodiversity populations to decline as a result of divergent changes in the timing of consumer demands and the availability of species that they feed on, highlights significant evidence gaps.

Irregular silviculture positively influences multiple bat species in a lowland temperate broadleaf woodland
Author: Alder, D.C., Poore, A., Norrey, J., Newson, S.E. & Marsden, S.J.
Published: 2020
Changes in woodland management have been linked to declines in birds and other wildlife but we know little about the impacts of such changes on our bat populations. All 17 of the bat species found breeding in the UK use woodlands and many are reliant on semi-natural broadleaved woodland. Because of the increasing pressures on our woodlands and their bat populations it is essential that we improve our understanding of how different types of woodland management affect their use by bats.
