- Abstract
- During the past fifty years pollinators in Europe have been declining. Agricultural intensification is considered to be main driver for this decline. In Europe agricultural schemes are used in order to e.g. maintain biological diversity. As a part of these schemes several European countries use flower strips to increase the amount of pollinators in the landscape. Status and Trends of European Pollinators (STEP) is an EU-funded project which aims to assess the current status and trends of pollinators in Europe. STEP also aims to evaluate and synthesize strategies to mitigate the decline in pollinators. As a part of the STEP project trap nests (used as artificial nest sites) where placed in sixteen field borders in landscapes with varying... (More)

STEP also aims to evaluate and synthesize strategies to mitigate the decline in pollinators. As a part of the STEP project trap nests (used as artificial nest sites) where placed in sixteen field borders in landscapes with varying complexity. Eight of the field borders were adjacent to a sown flower strip, whereas eight were not. The aim was to see if sown flower strips in agricultural landscapes benefit the reproduction of solitary bees and wasps. And also how landscape complexity effected the reproduction of these species and if the effect from the flower strips was higher in simpler landscapes that enhance normally few permanent flower resources. Neither flower strips, nor landscape complexity had any effect on the bees. The wasps however benefitted significantly from both flower strips and increased landscape complexity. This means that flower strips could be used in order to maintain biological diversity in Sweden. More research is needed on why bees did not benefit from flower strips, and if this depends on the design of the flower strips, or if solitary bees are not limited by lack of food, but rather by lack of nest sites.
