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.

Northern Ireland Seabird Report 2018
Author: Wolsey, S. & Booth Jones, K.
Published: 2019
Since 1986, seabird populations in the UK and Ireland have been monitored through the Seabird Monitoring Programme coordinated on behalf of partnership organisations by JNCC. Sample data on breeding abundance and breeding success of seabirds are collected from a large network of sites, both regionally and nationally, to enable species’ conservation status to be assessed. To examine trends at individual colonies, at country level and across the whole UK, it is essential that individual sites can be monitored consistently for many years.

Bird conservation and the land sharing‐sparing continuum in farmland‐dominated landscapes of lowland England
Author: Finch, T., Gillings, S., Green, R.E., Massimino, D., Peach, W.J. & Balmford, A.
Published: 2019
Agriculture is necessary to meet the food demands of an increasing human population, but it is also a leading threat to biodiversity, both because natural habitats are destroyed when land is converted to agricultural use and because the intensive management of existing agricultural land has negative consequences for many species. For this reason, scientists are studying strategies to mitigate the impacts of agriculture on biodiversity.
