Veteranisation
Veteranisation is a method to create old tree structures in younger trees and is mainly carried out using a chainsaw by arborists. The veteranisation methods aim to mimic effects on trees due to naturally occurring disturbances like storm felling, lightning, browsing animals and woodpeckers. Veteranisation will increase the number of available dead-wood-habitats for threatened species, as e. g. hollow trees, trees with partially dead trunks, and sap flows. This work will be done on some of the trees that otherwise would have been cleared in the restoration actions, and will be carried out by arborists. This method allows gradual increase in light to the adjacent trees.
The trees to be veteranised will be specified in the restoration plans. Veteranisation of trees will be done both adjacent to created glades and when thinning around veteran trees. This action is important for many threatened species since it will create long-lasting habitats in living trees. The actions that will be carried out in living trees include creating a nest box, ringbarking of large branches, ringabarking the top of the tree and mimicking a lightning strike. This action is important for many threatened species since it will create long-lasting habitats in living trees.
