BTO Research Reports are scientific papers that have been self-published by the BTO. The following is a full list of the published BTO research reports. Most are free to download, and links to Abstracts are included where possible.
Numbers missing from the list are those allocated but which were never produced or which have not been published. BTO recognises that, particularly in respect of commercially sensitive cases, a period of confidentiality is appropriate for some projects. However, in the interests of scientific development and dissemination of information, we encourage clients to permit publication as soon as it is reasonable to do so.

Birds of Conservation Concern Wales 4: the population status of birds in Wales
Author: Johnstone, I.G., Hughes, J., Balmer, D.E., Brenchley, A., Facey, R.J., Lindley, P.J., Noble, D.G. & Taylor, R.C.
Published: 2022
The latest review of the conservation status of birds in Wales. The report assessed all 220 bird species which regularly occur in Wales. There are now 60 species of bird on the Red List, with 91 on the Amber List and just 69 - less than a third of the total number of species - on the Green List.

Reports Birds of Conservation Concern
Rare and declining bird species benefit most from designating protected areas for conservation in the UK
Author: Barnes, A.E., Davies, J.G., Martay, B., Boersch-Supan, P. H., Harris, S.J., Noble, D.G., Pearce-Higgins, J.W. & Robinson, R.A.
Published: 2022
The loss of biodiversity is one of the most pressing issues globally. Efforts to tackle the issue include the use of protected areas, which are designated to protect species and/or their habitats from anthropogenic threats. But how effective are protected areas at achieving the desired biodiversity benefits?

Benefits of protected area networks for breeding bird populations and communities
Author: Sanderson, F.J., Wilson, J.D., Franks, S.E. & Buchanan, G.M.
Published: 2022
The European Union’s Natura 2000 network is the largest continent-wide effort to conserve biodiversity through a protected area network. The Natura 2000 sites are designated across the EU under either the Birds Directive or the Habitats Directive, based on objective assessment of a site’s importance for species (Special Protection Areas – SPAs) or habitats (Special Areas of Conservation Concern – SACs). Following the UK’s departure from the European Union, these sites are now covered under domestic legislation. They enable the UK to meet its international obligations for biodiversity conservation through protected area coverage. But how effective are these sites, and are they more effective than other forms of site protection?

Acute impacts from Teflon harnesses used to fit bio-logging devices to Black-legged Kittiwake Rissa tridactyla
Author: Clewley, G.D., Cook, A.S.C.P., Davies, J.G., Humphreys, E.M., O’Hanlon, N.J., Weston, E., Boulinier, T. & Ponchon, A
Published: 2022
BTO research underlines the importance of assessing the impact of tagging on a species by species basis, and suggests that the tag-attachment methods successfully used on other seabird species might not be suitable for Red-listed Kittiwakes.
