This study is summarised as evidence for the intervention(s) shown on the right. The icon shows which synopsis it is relevant to.

Reduce the intensity of farmland meadow management Bee Conservation

A replicated trial of 13 meadows under the Swiss Ecological Compensation Area agri-environment scheme in 2004 found that the species richness and abundance of solitary and social bees visiting potted flowering plants were higher in meadows under the scheme than in adjacent, intensively managed meadows (Albrecht et al. 2007).

Reduce management intensity on permanent grasslands (several interventions at once) Farmland Conservation

A replicated trial in 2004 of 13 meadows managed under the Swiss Ecological Compensation Area agri-environment scheme for at least five years (Albrecht et al. 2007) found that the species richness and abundance of hoverflies (Syrphidae), solitary bees (Apidae) and large-sized pollinators (mainly social bees and butterflies (Lepidoptera)) visiting potted flowering plants were higher in meadows under the scheme than in adjacent, intensively managed meadows. The total area of each Ecological Compensation Area meadow (0.48 - 2.15 ha) had no significant influence on the wild pollinator communities in this study.
