Temporal trends of arthropod diversity in conventional and low-input meadows
Résumé
In Switzerland, efforts have been made to reduce the negative impact of intensive management in grassland ecosystems on biodiversity by introducing low-input meadows within an agri-environmental scheme. The management of low-input meadows is regulated in order to achieve environmental goals: restrictions in fertilisation, prescribed dates for mowing. This paper aims to compare temporal trends in species composition of spider, carabid beetle and butterfly communities in low-input and intensive meadows in two regions in Switzerland 1997-2004. Furthermore, temporal scale of changes in arthropod communities is stressed and consequences for management are discussed.
