BTO publishes various reports, from those covering the annual results of core surveys, through scientific studies, and on to those produced in partnership with other organisations. Many of these are published as BTO Research Reports. You can access all of our reports from here, though note that we are currently updating the reports section, working backwards through time to bring all of the report pages into a consistent format. You can read our Annual Report and Accounts in the Governance section.

Investigating wader breeding productivity in the East Cairngorms Moorland Partnership Area using collaborative methods
Breeding wader populations have declined significantly in recent decades in the UK. During this time, areas of moorland managed for grouse shooting and adjacent areas of rough pasture have been identified as persisting strongholds. A contributory cause to wader population declines is afforestation, and in the Cairngorms National Park (CNP) there is likely to be significant woodland expansion (with associated conservation gains for woodland biodiversity) in areas currently holding breeding waders. Land management planning in the CNP requires a balance between these and other competing objectives.

BirdTrends 2018
The BirdTrends 2018 report is a one-stop shop for authoritative information about the population status of the common breeding birds of the wider UK countryside. The report is based on data gathered by the many thousands of volunteers who contribute to BTO-led surveys.

Review of data and monitoring options for assessing the status of breeding wader populations in the Yorkshire Dales National Park
Breeding waders are among the birds of highest conservation concern in the UK. The findings of recent national scale surveys suggest that the Yorkshire Dales National Park (YDNP) supports important breeding concentrations of several wader species.

Updating information on the period of reproduction and prenuptial migration for UK and Irish species included on Annex II of the EU Birds Directive
Article 7(1) of the European Union’s Directive 2009/147/EC on the conservation of wild birds allows for the hunting of species included within Annex II, where such hunting does not jeopardise conservation efforts. Article 7(4) of the Birds Directive further clarifies that species should not be hunted during their reproductive period or, if the species are migratory, during their prenuptial migration. To ensure effective implementation of these requirements, the European Commission requires Member States to identify the extent of the reproductive period and, where applicable, the timing of prenuptial migration for species included on Annex II that occur on their territory. A review of the best available information on the period of prenuptial migration and reproduction of each huntable species, for each Member State where that species occurs, was first carried out in 2001. The review was updated in 2009 and again in 2014, primarily to fill in missing data, especially for new Member States, but also to address inconsistencies within the species information available. This research report uses the latest BTO information to provide a further update.
