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.

An indicator highlights seasonal variation in the response of Lepidoptera communities to warming
Author: Martay, B., Monteith, D.T., Brewer, M.J., Brereton, T., Shortall, C.R. & Pearce-Higgins, J.W.
Published: 2016
As the effects of climate change are becoming ever more evident and widespread, methods to measure the impact on ecological communities and to understand how such impacts occur are more valuable. Recently published research, led by the BTO in collaboration with the Centre for Ecology and Hydrology, BioSS, Butterfly Conservation and Rothamsted Research, describes the development of a new indicator for detecting the effect of climate change in British butterflies and moths, which also provides new insights into when species are most sensitive to change.

Density-dependence and marine bird populations: Are wind farm assessments precautionary?
Author: Horswill, C., O'Brien, S. & Robinson, R.A.
Published: 2016
As the number of offshore wind farms increases, it is important to correctly assess the impact that these developments can have on wildlife. New research led by the BTO examines this situation for seabirds, considering the current environmental impact assessment process in light of the key factors that determine seabird population dynamics.
