Wild pollinator populations are declining in many regions, driven by land-use change and pesticides.
The IPBES assessment on pollinators, pollination and food production concluded that many wild pollinator species are declining in distribution and abundance in Europe and North America, and identified land-use change, intensive agricultural management, pesticides, invasive species, pathogens and climate change as the principal drivers.
What this does not claim: This is not a claim that honey bees are endangered — managed colony numbers have risen globally. Nor is it a claim that any single driver dominates everywhere, or that pollinator declines are uniform across regions and taxa; the assessment is explicit that data are far better for Europe and North America than elsewhere.
