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 2013

Published: 2013
The report summarises information on trends in more than 3100 species within the major taxonomic groups assessed. The report presents a new Watchlist Indicator, a cross-taxa priority species indicator that tracks changes in the abundance of 155 high priority species for conservation for which trend data are available. This demonstrates that, overall, conservation efforts to reverse the declines in these species have not yet succeeded, and highlights the need to refine the Watchlist Indicator and produce comparable measures from a broader range of species.This report is an excellent use of the population trends produced with the high quality bird data collected in the BTO’s major partnership schemes.
