Crown reduction is the pruning of a tree, and is most often applied when a tree has grown too large for it’s surroundings. Crown reduction is preferred to topping, because it leaves the tree in a more natural look, decreases the need for more future work and minimises stress and bother.
Crown thinning involves removing a number of secondary branches in such a way that it produces a balanced crown structure, without altering the overall size or shape of the tree. It results in improved light levels passing through the canopy thus reducing shading.
Crown lifting is often carried out where more head room is needed underneath trees branches giving clearance for people and vehicles. This involves the complete or partial removal of branches to give a specified clearance from the ground, to give unhindered movement around the tree.
