Oak Reduction

On inspection, this roadside oak was found to have hollowing and a large area of bark necrosis on the far side of the stem from the road. The extent of necrosis and hollowing was gauged using a nylon mallet.

The tree is about 20m tall and 1m girth at the base.

It was deemed appropriate to reduce the tree due to it being at the side of a road. One of the buttress roots was hollow, which appeared to be linked to the bark necrosis and hollowing.A Perenniopora fraxinea bracket was found on a branch 5m off the ground.

(Perenniopora is usually confined to the base of a tree. This is an unusual case because the bracket was found on an oak branch.)

When reducing such trees, it is important to be sympathetic. One should take care not to smash the lower canopy as this is the part of the canopy that the tree will rely on when 'growing down'. The lower canopy can be thought of as the tree's old age pension.
