Wild Bat Conservation and Welfare

Bats are among the most ecologically important and welfare-neglected wild mammals, facing threats from habitat loss, wind turbines, pesticides, and emerging diseases.

Key Facts

Over 1,400 bat species exist globally — comprising approximately 20% of all mammal species.
White-nose syndrome, caused by the fungus Pseudogymnoascus destructans, has killed over 6 million North American bats since 2006.
Bats consume vast quantities of pest insects — a single brown bat may eat 600 mosquitoes per hour.
Wind turbines kill an estimated 200,000-500,000 bats annually in North America through direct blade strikes and barotrauma.
Bat maternity roosts in buildings and trees are legally protected in many countries but frequently disturbed during renovation work.

Welfare Considerations

Wild bat welfare encompasses both individual suffering and population-level threats. Individual bats suffer from disease, injury, and starvation, while population declines represent cumulative welfare losses at massive scale. White-nose syndrome represents one of the most severe wildlife disease emergencies of the 21st century. Wind turbine mitigation (feathering blades at low-wind periods when bats are most active) can reduce fatalities by 50-90% with minimal energy generation impact.

What You Can Do

Install bat boxes in gardens to provide roosting habitat, particularly near linear features like hedgerows.
Report bat roosts to local bat conservation groups before undertaking building work affecting potential roost sites.
Support wind energy developers that implement bat-friendly operational settings during peak activity periods.
Donate to bat conservation trusts working on white-nose syndrome treatment and population monitoring.
