Its the intentional wounding of trees to create decaying wood habitat commonly replicating natural wounds and habitat features commonly found on trees.Its a slightly misleading term as we never undertake this work on veteran trees, we priotise this work on trees that are already earmarked for removal or to have work done to them.
Why do we do this?
Veteran trees sustain all sorts of damage through storms, pruning, animal activity and pest attacks. With time, these wounds develop onto wood decay habitats which provide a huge selection of habitats for fungi invertebrates, birds and mammals. Young trees tend be fairly scarce of these features, they simply haven't lived long enough to endure the wounds of veteran tree life. Some wildlife such as Violet Click Beetles are completely dependent on these niche features and when a veteran tree finally dies and decomposes back into the soil the beetles need a new host, problem being, they are only capable of flying a few hundred metres so if there isn't a new home to move into close by, they will die off.
Its important to create decaying wood habitat where there is an age gap in a veteran tree population or where there is lack of wood decay habitat such as in a young group of trees.
How do we do it?
We use chainsaws, axes, winches, mallets, drills and ropes to mimic nature and speed up the process of decay related habitat. We can replicate rips,loose bark, woodpecker holes, insect sap sucking insects, horse, cattle damage, lightining strikes, cavities and aeriel deadwood...
To learn more about veteranization check out our case study below.
We have the skills and experience to undertake veteranization of your trees and deadwood management to enhance biodiversity.
There are many ways to increase biodiversity using deadwood from habitat piles to attaching aerial deadwood to branches.
Initiating pollarding fast tracks decay in trees and should be done when a tree is young. Pollarded trees also allows for more trees in an area as pollarded trees need less room than maidens.

Every good project starts with a good plan. We can assess your site and provide exert advice on how we can promote and increase biodiversity using these techniques.


Since the winter of 2013 we have been undertaking veteranization in a 6 acre woodland every winter to increase biodiversity by habitat creation and making the woods a richer, diverse habitat..inspired by Burnham Beeches Nature Reserve the longer term aim is to create patches of lower density wood pasture with pockets of higher density closed canopy.
We initiated pollarding trees with inferior form that would be felled as part of a thinning program we leave the better ones to become standards. All arisings are dead hedged to create more deadwood habitat and develop soil quality. The survival rate so far is around 90% and the 10% dead adds more valuable standing deadwood.
Its been a training ground for the Treeation Crew to hone in our skills and to review what has worked and what hasn't. As the years have gone by we have tried new techniques such as: coronet cut pollards, instigated rip cuts, bored out cavities, added union separation cracks and partially broken off limbs.
It was very encouraging to see decay fungi fruiting on these pollards after around 2 years of the project commencing, clearly showing diversity was increasing among the trees as shown with presence of King Alfred's cake decay fungi in the image.
