A recent international study, published in the journal “Science” and involving researchers from the University of Freiburg, suggests the European Union’s biodiversity strategy falls short of adequately safeguarding vital pollinator populations. The research indicates the current EU target of dedicating 10% of agricultural landscapes to natural or semi-natural areas is insufficient to ensure the long-term stability of pollinators such as wild bees, bumblebees and butterflies.
The study found that stable pollinator populations require a significantly higher proportion of these areas, ranging from 16% to 37% within agricultural landscapes. Specifically, certain crucial pollinator species, including wild bees and bumblebees, necessitate 16% to 18% of near-natural habitats for survival, while butterflies require as much as 37%.
Beyond the sheer acreage, the quality of these habitats is also highlighted as a critical factor. Researchers emphasize the importance of recognizing and rewarding farmers for creating and maintaining these natural environments. Long-term commitments, ideally spanning at least 20 years, are proposed to secure lasting habitats offering both essential food sources and nesting opportunities for pollinators.
