Background information and definitions
This intervention involves leaving a minimum distance between wind turbines and bat roosts or habitat features to create a buffer zone. The EUROBAT guidance on bats and wind turbines recommends a minimum distance of 200 m between wind turbines and important bat habitats (Rodrigues et al. 2014). Natural England, UK recommends a minimum distance of 50 m from the turbine blade tip to the nearest bat habitat feature (Mitchell-Jones & Carlin 2012), and for micro turbines a minimum distance of 20 m has been recommended (Minderman et al. 2012). However, reduced bat activity has been recorded up to 1,000 m from wind turbines (Barré et al. 2018). This action may not protect migratory bat species. Bennet & Hale (2018) found high fatalities of migratory bats at wind turbines without bat habitat features nearby (e.g. in open grazed fields).
