Action: Reduce turbine height
Key messagesRead our guidance on Key messages before continuing
- We found no studies that evaluated the effects of reducing turbine height 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.
Studies of patterns of bat fatalities at existing wind farms in Europe and the USA have shown that greater numbers of bats are killed at taller wind turbines (e.g. Barclay et al. 2007, Rydell et al. 2010, Georgiakakis et al. 2012).
