Wild Bee Population Decline and Ecosystem Welfare

Wild bee populations are declining globally due to habitat loss, pesticides, disease, and climate change, with consequences for ecosystem health and the indirect welfare of countless species that depend on pollination.

Key Facts

Over 20,000 wild bee species exist globally, compared to one managed honeybee species
Wild bees are responsible for approximately 80% of wild plant pollination worldwide
One-third of wild bee species in Europe are declining and 9% face extinction risk
Neonicotinoid pesticides impair navigation, foraging, and reproduction in bumblebees and solitary bees
Loss of flower-rich habitat is the primary driver of wild bee decline in agricultural landscapes
Wild bees pollinate the majority of wild flowering plants that provide food and cover for vertebrate wildlife
Rewilding farmland margins and reducing pesticide use are the most impactful conservation interventions

Welfare Considerations

Wild bee welfare is complex — individual bees have limited cognitive capacity compared to vertebrates, but the ecological consequences of their decline cascade to affect the welfare of countless animals that depend on the fruits, seeds, and habitat structure created by pollination. From a welfare perspective, the irreversible loss of pollinator populations represents an ecosystem-level harm with wide-ranging consequences. Additionally, evidence that bees can experience states analogous to positive and negative affect makes their welfare a direct moral concern worth taking seriously.

What You Can Do

Plant diverse native wildflowers in gardens, verges, and community spaces to support wild bees
Advocate for reduced pesticide use and neonicotinoid bans near agricultural and natural areas
Support agri-environment schemes that pay farmers to maintain flower-rich field margins
Avoid disturbing ground-nesting bee sites in gardens and lawn areas
Donate to Bumblebee Conservation Trust and similar organizations protecting wild bee populations
