Artificial lighting schemes can damage bat foraging habitat directly, through loss of land and fragmentation, or indirectly by severing commuting routes from roosts, polluting watercourses and foraging habitat. The impact of street lighting on bat activity was tested using experiments along lesser horseshoe bat commuting routes at eight sites across Wales and South West England. Hedgerows were illuminated at a mean of 53 lux using two portable high-pressure sodium street lights. Bat activity was recorded using AnaBat remote acoustic detectors.
