Action: Close off potential access points on turbines to prevent roosting bats
Key messagesRead our guidance on Key messages before continuing
- We found no studies that evaluated the effects of closing off potential access points on turbines to prevent roosting bats on bat populations.
‘We found no studies’ means that we have not yet found any studies that have directly evaluated this action during our systematic journal and report searches. Therefore we have been unable to assess whether or not the action is effective or has any harmful impacts. Please get in touch if you know of such a study for this action.
Bats have been observed roosting in the nacelles of wind turbines (Ahlén et al 2009), as well as in turbine door slats, stairwells and between the gills of the transformer (Bennett et al 2017). Closing off potential access points on wind turbines to prevent bats from roosting may reduce the risk of bat collisions with turbine blades.
