Tree work specification

Well, what is decent tree work specification ? In my view it’s when you look at the tree in question holistically. Look at the tree itself, it’s surroundings, the impact it has on its locality, both positive and negative. It’s when you speak to the client or owner of the tree, you listen. You draw from years worth of practical and intellectual skill. Hopefully all of this combines to the end result being the correct tree work specification.

This tree is question…

is a Fagus slyvatica – common beech and its a real beauty. It stands over the people on the ground dwarfing them. It measures 25metres in height and is a real specimen tree. However, it has some issues. The owner of this tree is aware of their duty of care and so has the tree inspected annually by Harroway Trees

John carried out a sonic test of the tree, this showed him and us if any issues were present in the tree itself. Think “Tree X-ray” and you’re not far off!

Results?

To everyone’s surprise this outwardly healthy looking tree – it had a full crown, very close to no deadwood present and full of vigour was under attack. The Picus test showed a cavity in the main stem indicated by an area of low sonic velocity.

What caused this?

Difficult to say, no fungal brackets were found on this test but on the last visit Kretzchmaria deusta was noted present. The assumption is this is the cause of the internal rot. Now, this is where years of knowledge pays dividends. It could easily be a knee-jerk reaction time and it could be said that this amazing tree needs to be felled on grounds of safety. No – not so. Drawing on years of experience a specification of

“it would now be prudent to carry out a reduction in the tree’s height by approximately 2-3 metres, depending on the opportunities for cutting back to suitable live growth in each instance”

This is where we came in.

Leading arborist Joe carried out the task of pruning this tree, he used his years of experience to get to the correct points in the tree and carry out an incredible job of executing the spec to the letter. I think you’ll agree the quality here shines. We are often told as Arborists that the sign of a good job is one where the results are natural and hard to see where intervention has taken place. In this case both boxes are ticked.

                          Well done lads.

Even the sun came out!
