Native bees are far more diverse than honeybees and provide irreplaceable pollination services. Their decline from habitat loss and pesticides deserves welfare and conservation attention in its own right.
Native bees are ecologically irreplaceable — many plant species co-evolved with specific native bee pollinators whose foraging behavior matches flower structure. Their welfare is collective and habitat-dependent rather than individually tractable. Loss of native bee habitat removes the conditions for entire local populations to survive. Pesticide exposure kills individuals and impairs reproductive success at sublethal doses. The welfare case for native bee protection is both precautionary on sentience grounds and ecologically urgent.
