Solar parks could boost bumble bee numbers in a win-win for nature
New research shows that simple changes to how UK solar parks are managed could boost ground nesting bumble bee populations in the parks and surrounding areas, providing an additional benefit on top of renewable energy.
Solar parks could boost bumble bee numbers in a win-win for nature
These preliminary results will be presented at Ecology Across Borders on Monday 13 December by Hollie Blaydes, a PhD researcher at Lancaster University.
Using a model that simulated bumble bee foraging in UK solar parks, researchers at Lancaster University investigated different management scenarios that offered varying degrees of resources for bumble bees. Their findings indicated that solar park land managed as meadows offering the most resources would support four times as many bumble bees as solar park land managed as turf grass.
They also found that large, elongated and resource-rich solar parks could boost bumble bee density up to 1km outside of the parks themselves, delivering pollinator services to crops in surrounding agricultural land.
Hollie Blaydes said: Our findings provide the first quantitative evidence that solar parks could be used as a conservation tool to support and boost pollinator populations. If they are managed in a way that provides resources, solar parks could become valuable bumble bee habitat.
In the UK, pollinator habitat has been established on some solar parks, but there is currently little understanding of the effectiveness of these interventions. Our findings provide solar park owners and managers with evidence to suggest that providing floral and nesting resources for bumble bees could be effective.
