Organic animal farms benefit birds nesting in agricultural environments
(PHYSorg.com Biology)

The abundance of bird species living in agricultural environments has decreased both in Finland and elsewhere in Europe. Attempts to rectify the situation have been made with the help of agri-environment-climate subsidies. They are granted to agricultural producers by the EU for implementing measures that are presumed to be beneficial to the environment. There is a range of such subsidies, but their potential effects on biodiversity at national scales have been seldom comprehensively investigated.
