The aim of the project is to monitor the population size changes of Swedish breeding birds. Since 1975, birds are counted in summer and winter at hundreds of different sites using standardized methods. In this way about 150 of the 250 breeding species are surveyed. The project was started by Sören Svensson and led by him until I took over in 2002.
Species-specific trends are updated yearly and published in a report and on the homepage. Apart from the species trends being important in themselves, they are also combined into indicators that are used in various ways to indicate development of biodiversity. At the national level, bird indicators are used to assess the progress towards achieving them the environmental objectives set by the Swedish parliament (see link on the right). Presently there are indicators for Flourishing lakes and streams, Thriving wetlands, Sustainable forests, A varied agricultural landscape, A magnificent mountain landscape and A rich diversity of plant and animal life. Internationally, our data are included in the Wild Bird Indicator of the European Union (see link on the right). There are several ongoing collaborations with scientists in Sweden based on our bird monitoring data.
