Retain veteran and standing dead trees as roosting sites for bats
Overall effectiveness category No evidence found (no assessment)
Number of studies: 0
Background information and definitions
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.
To be included as evidence for this intervention, studies must have monitored a comparison, i.e. compared areas where veteran and standing dead trees have been kept as roosting sites for bats with similar/nearby areas where they have been removed. There must have been an active decision (i.e. intervention) to retain the trees and the study must state when the intervention was carried out.
For an intervention that involves creating roost features in trees, see ‘Create artificial hollows and cracks in trees for roosting bats’. See also ‘Create or restore bat foraging habitat in urban areas’ for one study that uses snag recruitment alongside other practices for forest restoration.
