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.

State of Nature report 2016
The State of Nature report is an assessment of how nature is doing across the UK. As well as an overarching assessment of UK flora and fauna, there are separate reports for England, Scotland, Northern Ireland and Wales to look at each country in more depth. The reports pool data and expertise from 53 nature conservation and research organisations, a partnership unparalleled in UK conservation.View a summary presentation of the State of Nature 2016.The BTO is proud to be a founding member of the State of Nature Partnership and our long-term volunteer-based monitoring schemes are key to such assessments. It is extremely important that well-structured monitoring to track changes in biodiversity continues and that good evidence is collected to identify the causes of change. Publicising the results and engagement with the public as well as policy-makers is essential to the success of any project based on citizen science.
