Close off potential access points on turbines to prevent roosting bats
Overall effectiveness category No evidence found (no assessment)
Number of studies: 0
Background information and definitions
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.
