BEFORE

This is the removal of selected branches and limbs from the lower part of the trees crown, which raises the clearance above ground level.

Extensive crown lifting should if possible be phased over a number of years. With a view to providing some opportunity for both physiological and biomechanical reactions to compensate for the wounds and branch removal, inflicted upon the tree. Crown lifting on a mature tree should be avoided or restricted to secondary or minor branches wherever possible.

AFTER

Branches that are removed in a close proximity to one another, could cause problems in the respect of cavity could originate closely to one another and could potentially coalesce.
