Does your tree overhang the footpath and highway? Or, Do you need to lift the lower branches in order to gain access to a site?
Crown lifting involves pruning lower canopy branches to achieve a desired vertical clearance from ground level to nearest foliage. The most common reason behind crown lifting a tree is to get the desired clearance on footpaths and highways to make sure the canopy isn’t exposed to damage from passing vehicles.
When crown lifting a tree the work should be subtle. The desired live crown left after the work has been carried out is at least two-thirds of the height of the tree.
