Crown reduction should not be used to reduce the chances of the tree blowing over in a storm. Crown Thinning is the preferred method to minimize storm damage of an otherwise structurally sound tree.
Crown reduction can be considered when the root system of a large maturing tree has substantial decay making it potentially hazardous or on a tree with a high rating.
The objective is to make cuts so that the foliage is left intact on the outer edge of the new, smaller canopy ideally, pruning cuts should not be evident when you stand back from the tree after pruning.
Each tree will be individually considered in relation to the:
shape, size, character, condition, site and species of tree.
All operations will be completed leaving each tree in an acceptable, well-balanced and safe condition. Each branch will be removed using the ABC cut method where risk of tearing is reduced.
All final cuts will be made at the branch collar, with the branch collar remaining intact. Under no circumstances will any flush cuts be made.
Section felling will be used in situations where there is a risk of damage occurring to any property or harm to the public. The work consists of the entire removal of the tree, in sections. If a delay between felling and stump removal is to occur, the stump will be left at a minimum height of 1.5 metres.
The straight fell of trees is the removal of trees as a single unit. Straight felling will be limited to such situations that pose no risk of damage to any property or persons whatsoever.
Thinning crowns to let in more light by removing some, usually up to 30 percent, of the branches and concentrating on dead or congested shoots is another strategy. It is very easy to spoil the appearance of the tree so this is best attempted in stages evaluating the effect before removing more.
Lifting the crown by removing lower branches will allow access under the tree, for mowing access, space under the tree to sit and enjoy the view and provide shade in the summer and enjoying the shades cast by the tree. It is sometimes a useful task to prevent children from climbing trees to avoid accidents.
