摘要: To study effects of short-term land-use changes on birds in a predominantly agriculturally used landscape Northeastern Austria, were surveyed 22 circular areas with diameter 1 km 2005 and 2009. Because the abolition to obligate set-aside land from 2008, it was suspected that amount would be reduced dramatically. Consequently, loss farmland expected. Results show indeed decreased significantly between 2009 15.05% 9.69% (mean proportion per area). Farmland represented by 20 species both years. Neither richness abundance nor composition affected land. The these landscapes already high (compared other Austria) before amendment law still relatively after it. Therefore, perhaps extent below threshold find detectable birds.
