Bat Conservation and Welfare: White-Nose Syndrome and Urban Roost Protection

Bat populations worldwide face threats from white-nose syndrome, wind turbine collisions, roost destruction, and pesticide use — yet bats remain poorly understood and underprotected relative to their ecological importance and welfare needs.

Key Facts

White-nose syndrome, caused by the fungus Pseudogymnoascus destructans, has killed an estimated 5.7-6.7 million bats in North America since 2006
The disease kills bats during winter hibernation by causing them to wake repeatedly, depleting fat reserves until they starve or freeze
In the UK, all bat species are legally protected, and disturbing roosts — even in your own home — is a criminal offence
Bats can live 20-30 years and reproduce slowly, meaning population recovery from large-scale mortality events takes decades
Wind turbines kill an estimated 600,000-900,000 bats annually in the US through direct strikes and barotrauma from pressure changes near blades
Insectivorous bats provide enormous ecosystem services including pest control worth billions of dollars annually in agricultural protection
Urban roosts in buildings provide essential refuges for many bat species, and roost exclusion during maternity season can kill pups unable to survive without their mothers

Welfare Considerations

Bats experience genuine suffering during white-nose syndrome mortality events — they starve slowly over weeks during hibernation disruption, a prolonged and distressing death. Wind turbine barotrauma causes acute internal haemorrhage that may not cause immediate death, potentially leaving bats injured. Roost destruction during maternity season separates mothers and pups, causing starvation of dependent young. The welfare case for protecting bats is strong both because they can suffer significantly and because they provide irreplaceable ecosystem services that benefit other animals and humans. Their slow reproduction makes welfare-related mortality especially damaging to population recovery.

What You Can Do

Never disturb bat roosts in your home — contact the Bat Conservation Trust for advice on legal and welfare-safe management
Plant night-flowering plants and maintain insect-rich gardens to provide bat foraging habitat
Install bat boxes in your garden or on your home to provide additional roost sites
Support campaigns for wind turbine curtailment during high-risk bat migration periods
Reduce pesticide use to maintain the insect prey base that bats depend on
Donate to Bat Conservation International or national bat conservation organisations
Learn bat call identification to monitor local bat populations and contribute to citizen science surveys
