Action: Provide deadwood/snags in forests
Key messagesRead our guidance on Key messages before continuing
- We found no evidence for the effects of providing deadwood/snags in forests on bird populations.
'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.
Snags (standing dead trees) and other dead wood can be important for nesting, roosting and feeding for many bird species. Providing this has therefore been suggested as a way to increase habitat carrying capacity and population sizes. Studies describing the effects of providing artificial snags are described in ‘Provide artificial nesting sites’.
