Barn Owl Conservation: Reversing Agricultural Decline

Barn owls have declined dramatically across agricultural landscapes due to habitat loss, rodenticide poisoning, and road mortality, but targeted conservation can help reverse their decline.

Key Facts

UK barn owl populations declined by 70% during the 20th century due to agricultural change
Barn owls rely on rough grassland margins for vole hunting
They are highly susceptible to second-generation anticoagulant rodenticides through prey
Road mortality is a major cause of death, particularly for juveniles dispersing from nest sites
Nest box programs have successfully supported local population recovery

Welfare Considerations

Barn owls face chronic welfare challenges from inadequate prey availability in intensively farmed landscapes. During harsh winters, owls can starve when snow cover prevents access to voles. Anticoagulant rodenticide poisoning causes internal hemorrhaging. Road strikes cause acute trauma. The Barn Owl Trust's research shows that providing rough grassland margins and nest boxes can dramatically increase local breeding success, directly improving welfare for owl families.

What You Can Do

Install barn owl nest boxes on suitable rural buildings following Barn Owl Trust guidance
Maintain or create rough grassland margins around fields on any land you manage
Avoid second-generation anticoagulant rodenticides and report illegal use
Support agri-environment schemes that include barn owl habitat creation
