Linkages between biodiversity and ecosystem services in grazed and abandoned semi-natural grasslands ?

摘要

In this study potential links between biodiversity, ecosystem service (ES) indicators and agricultural land use were examined. Semi-natural grasslands, either actively used for sheep grazing or abandoned, were surveyed and all vascular plant species recorded. Based on this survey, species richness (per 4 m2), fodder quality and quantity, as well as pollination, were estimated. We found lower species richness and indications of lower fodder quantity and quality, but of higher pollination in abandonedgrasslands. 'The relationships between ES indicators and species richness were both negative and positive, and differed in managed and abandoned semi-natural grasslands.
