The importance of the qualitative composition of floral margins to the maintenance of rich communities of bees

Abstract: The transformation of natural environments due to the intensification of agriculture has had negative effects on the communities of bees, with negative side-effects on pollination, in both farmed and natural systems. The addition of herbaceous plant edges to crop fields may improve the abundance and diversity of pollinators. The present study emphasises the importance of the right choice of plant species in floral margins to improve the abundance and diversity of bees.
