Résumé :	The development of the breeding bird Communities in a river valley in Schleswig-Holstein after introducing low intensity large-scale grazing was investigated. A second part of the river valley that resembled the study area in land use and site conditions was used as a reference site. In the beginning of investigations, both sites were dominated by abandoned wet grassland without shrubs.. Land use of the reference site remained unchanged during the five study years. Breeding bird numbers decreased significantly after the introduction of large-scale low intensity grazing compared to the reference site. The decrease based mainly on a loss of unthreatened herb layer breeders. The highest decline was recorded in formerly abandoned grassland where year-round grazing produced a homogeneous and short vegetation structure in springtime.
