Action: Retain veteran and standing dead trees as roosting sites for bats
Key messagesRead our guidance on Key messages before continuing
- We found no studies that evaluated the effects of retaining veteran and standing dead trees 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.
Veteran or damaged trees (of any age and size) and standing dead trees (‘snags’) can provide important roosting sites for bats within crevices, cavities and behind loose bark.
For an intervention that involves creating roost features in trees, see ‘Habitat restoration and creation – Create artificial hollows and cracks in trees for roosting bats’. See also ‘Threat: Residential and commercial development – Create or restore bat foraging habitat in urban areas’ for one study that uses snag recruitment alongside other practices for forest restoration.
