Conservation of the serotine bat, one of the UK's largest bat species, in building roosts.
Key Facts
Serotine bats roost almost exclusively in buildings in the UK
They have a distinctive large wingspan and slow flapping flight
Cockchafers, moths, and other large insects are primary prey
UK populations are concentrated in southern England and Wales
Serotines are sensitive to roost disturbance from building renovation
Welfare Considerations
Serotine bats face welfare risks from roost destruction during building work, requiring bat survey and mitigation before any renovation affecting roost sites.
What You Can Do
Commission a bat survey before renovating buildings in areas with serotines
Support the Bat Conservation Trust roost advisory and monitoring services
Install large bat boxes suitable for serotine bats on south-facing building walls
