Crown thinning is the removal the leaf area of the canopy, the small secondary live woody growth, taking care to retain the framework branches. Normally no more than 25% of secondary growth would be removed in a single operation.
The aim of crown thinning is to produce an even canopy of foliage on a well structured, framework of limbs and branches, typical for the species of tree. Crown thinning does not generally include the removal of inner lower branches from the central area of the crown, most pruning wounds shall be made in the outer quarter of the canopy.
In confined spaces certain constraints recognised by the employer may result in the canopy having an un-balanced appearance upon completion of the work
