Wild Bee Welfare and the Pollinator Crisis

Wild bee populations are declining globally with significant consequences for ecosystem function, agriculture, and the welfare of individual bees experiencing habitat loss and pesticide exposure.

Key Facts

Over 20,000 species of bees exist globally with only a small fraction being managed honeybees
Wild bee populations have declined by 30% or more in many regions over recent decades
Habitat loss reducing flowering plant diversity is the primary driver of wild bee population decline
Neonicotinoid pesticides cause disorientation, impaired foraging, and colony collapse in exposed bees
Wild bees are solitary in over 90% of species with diverse nesting habits including ground nesting and hollow stem nesting
Bumblebees show sophisticated spatial memory and demonstrate signs of play and positive emotional states in laboratory settings
Research suggests some bee species experience primitive forms of pain and stress from pesticide exposure
Garden and urban habitats with appropriate planting provide significant wild bee foraging and nesting support

Welfare Considerations

Wild bee welfare is an area where individual welfare science and population conservation are both relevant and intertwined. The evidence for bee sentience has advanced considerably: bees demonstrate sophisticated learning, spatial memory, and, in bumblebees, behaviour consistent with play and positive affect. Pesticide exposure causes neurological effects in bees that disrupt their foraging, navigation, and social behaviour in ways that represent welfare harm at the individual level. At the population level, the collapse of wild bee communities removes ecosystem services that other wild species and agricultural systems depend on. The individual welfare harm from pesticide exposure and habitat loss is therefore multiplied by the cascade effects on ecosystems. Garden-scale habitat creation is one of the most accessible ways for individuals to directly improve wild bee welfare while contributing to broader population recovery.

What You Can Do

Plant a diverse range of native flowering plants that provide nectar and pollen from spring through autumn
Eliminate pesticide use in your garden entirely, including systemic treatments on flowering plants
Create nesting habitat for wild bees including log piles, bare earth patches, and bee hotels with appropriate dimensions
Advocate for pesticide regulations that protect pollinators including restrictions on neonicotinoid use
Support organisations working on wild bee conservation through habitat restoration and research
