Standing deadwood, referred to as snags, not only looks beautiful in a forest but is also useful to the environment. 

It is beneficial to leave the snags standing during felling, because they contribute to the forest’s diversity. In forest certification systems, snags are trees earmarked for retention. Snags do not pose a threat to the forest as, for example, bark beetles do not feed on them. Whilst pest insects avoid snags, many beneficial insects, birds and small mammals find themselves at home in them, for example the common swift.
