Crop Farming and Wild Animal Welfare

Arable crop farming affects billions of wild animals annually through habitat destruction, pesticide use, and direct mortality during harvest operations, representing a significant and underexplored animal welfare issue.

Key Facts

Combine harvester operation during cereal harvest kills millions of small mammals and ground-nesting birds annually
Pesticide application eliminates insect populations that form the base of farmland food chains
Hedgerow removal has reduced farmland bird populations in the UK by over 50 percent since 1970
Field mice, voles, and rabbits are directly killed during tillage and harvest operations
Organic farming supports up to 50 percent more wildlife species than conventional systems
Precision agriculture reduces pesticide application area and reduces non-target species exposure
Measures including pre-harvest flushes using noise and flushing bars can reduce hare and deer mortality

Welfare Considerations

The welfare of wild animals on arable farmland has received remarkably little attention compared to farm animal welfare, despite the enormous scale of impact. Combine harvesters kill small mammals and leverets at high rates during harvest — animals that are typically not killed instantly but injured and left to die in crop rows. Pesticide poisoning causes prolonged neurological impairment and death in non-target species including insects, birds, and small mammals. Habitat simplification through hedgerow removal eliminates nesting sites and food sources, causing chronic food stress across farmland wildlife communities. These harms affect hundreds of millions of individual animals annually in just the UK alone.

What You Can Do

Support organic farming products which maintain higher farmland biodiversity and reduce pesticide impacts
Advocate for agri-environment schemes that reward farmers for wildlife habitat maintenance
Support measures requiring pre-harvest wildlife flushing to reduce direct mortality during harvest
Reduce food waste to lower the total farmland area required for food production
Learn about farmland wildlife welfare as an important dimension of sustainable food system advocacy
