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.

Northern Ireland Seabird Report 2017
Author: Wolsey, S. & Booth Jones, K.
Published: 2018
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.

Improving understanding of the possible relationship between improving freshwater and coastal water quality and bird interest on designated sites - phase 1 review
Author: Henrietta E K Pringle, Niall H K Burton
Published: 2018
Over the past 50 years there has been widespread improvement in water quality in many freshwater and coastal systems driven by domestic and European legislation, most recently the EU Water Framework Directive (EC Directive 2000/60/EC), but also including the Urban Waste Water Treatment Directive (EC Directive 91/271/EEC) and Bathing Water Directive (EC Directive 76/160/EEC).
