Policymakers Urged to do More to Protect Pollinators

Farming schemes could be doing more to help pollinators such as bees and hoverflies, according to a new international study. Researchers led by Scotland’s Rural College (SRUC) has found.

The study, published in the Journal of Applied Ecology, is the work of 22 experts across 18 different European countries. They identified substantial opportunities to improve the quality of agri-environmental habitats by implementing pollinator-friendly management practices. These would not only increase the abundance of resources in a habitat, but also the range of resources.

Where intensive farming and the subsequent loss of flower-rich habitats has been blamed for declines in pollinator species, the study suggests how collaboration could be the answer. By connecting isolated areas of nature-rich farmland and implementing diverse field margins, farmers could improve the fate of these much-needed pollinators. Other recommendations include planting nitrogen-fixing crops for foraging, ensuring habitats provide floral resources across a wider period of time and improving existing features for nesting, such as hedgerows and drystone walls.

Professor John Holland of the Game & Wildlife Conservation Trust (GWCT) notes:
“Of all the available agri-environment scheme options, flower-rich habitats on farmland are one of the best, supporting not only pollinators but other beneficial invertebrates that can help control crop pests.”

The potential impact of even a marginal improvement in habitat should not be overlooked. More than 70 per cent of crops worldwide rely on insect pollinators and previous studies show how pollinator-friendly management can also increase a number of other invertebrates, including natural predators.

Researchers evaluated how different options available within Ecological Focus Areas (EFAs) varied in their potential to support insect pollinators and how readily these options were used by farmers.

The findings of the study, which was funded under the Cost Action Super-B – Sustainable Pollination in Europe programme, will be used to inform the Common Agricultural Policy post-2020.
