Paper abstract bibtex In Europe, many rare birds species or species whose populations are with very local distribution have benefited from special protection under European Union (EU) policy (e.g. Directive 2009/147/EC and the Natura 2000 network), while the populations of many common and widespread species have declined, with the greatest losses reported for farmland birds. Based on monitoring data for the period 2005-2010, we studied the trends in abundance and species richness of common breeding birds in Bulgaria before and after the country joined the EU in 2007. We analysed the trends in birds of farmland, woodland and "other" habitats, and additionally, we tested whether indices of the commonest birds are representative of wider changes in bird populations. At species level (n = 32), significant declines were detected in 11 species (34%), and increases in just two (6%); 19 species (60%) had uncertain trends. There were mean declines of 15% in farmland birds, 5% in woodland birds and 24% in birds of other habitats. Both species richness and total abundance of common birds were higher before the accession of Bulgaria to the EU than after. These trends may be explained by two contrasting processes - agricultural intensification in the plains, and land abandonment in agriculturally less productive mountainous and hilly areas. Conservation measures, delivered through policy governing the management of agricultural land, should be funded adequately and targeted appropriately to stop and reverse the decline in common and widespread birds in Bulgaria. © 2017 Institute of Biodiversity and Ecosystem Research - BAS.
