Canopy (or crown) reductions are a way of maintaining your tree. A WAF climber makes his way throughout the canopy reducing the crown by shortening the branches in length – and so, changing the overall size and shape of the tree. Reductions are usually carried out all around the outer parts of the crown to maintain a balanced shape, seldom should it include cutting through the main stem.  Often we are asked to partially reduce tree canopies from buildings, roofs or guttering. The amount of reduction agreed between WAF and the customer is stated in terms of intended height and spread of the tree after pruning (as opposed to the % of the overall crown removed).
