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.

Robustness of simple avian population trend models for semi-structured citizen science data is species-dependent
Author: Boersch-Supan, P.H., Trask, A.E. & Baillie, S.R.
Published: 2019
Accurate and robust population monitoring is essential to effective biodiversity conservation, and is at the heart of BTO’s mission. While all BTO-led surveys and schemes are volunteer driven, observation protocols differ among them, spanning the range from the highly structured BTO/JNCC/RSPB Breeding Bird Survey (BBS) to BirdTrack, which allows for the submission of casual observations by any interested birdwatcher. A new BTO study now compares data from these two schemes to see whether trends in BirdTrack reporting rates are comparable to population trends derived from BBS data.

Flowers of the Brecks Part 2: Wetland, Woodland & Farmland
Author: Mike Crewe
Published: 2019
The Brecks form a unique area of inland East Anglia, straddling the counties of Norfolk and Suffolk. Recognised as one of the most important parts of the United Kingdom in terms of biodiversity, they encompass tracts of forest, heathland and arable farmland, threaded by river corridors. These diverse habitats support a range of fascinating wildlife.
