Action: Conserve existing roosts within developments
- We found no evidence for the effects of interventions to conserve existing roosts within residential or commercial developments.
'No evidence' for an action means we have not yet found any studies that directly and quantitatively tested 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.
Many bat species are known to roost in the crevices and roof voids of buildings. Existing roosts can be conserved during residential or commercial developments, for example by retaining a roof space used as a roost during renovations. It is possible that with laws protecting bats in many countries, and with stricter planning and licencing requirements in the UK, for example, the consideration of bat roosts during residential and commercial development of buildings is benefitting bats. However, we found no studies examining the effects of attempts to conserve existing bat roosts in buildings during developments and encourage those working in this and related areas to publish their findings.
