Comparative analysis of conventional and organic farming systems: Diversity and abundance of farmland birds
A comparative study on the abundance of breeding birds and wintering birds was carried out over the period 2005-2007 in conventionally and organically managed arable fields in Northern Germany. Birds were surveyed on 40 (breeding season) and 35 (non-breeding season) pairs of fields (conventional/org...
