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.
Crown reductions are also a good idea if you have telephone lines near trees, as the tree grows their branches can interfere with the cables.
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. Section felling is the best way of removing a tree, if it is necessary. Some trees that show signs of disease, may in some circumstances be saved by cutting off the dead wood/branches to allow for new growth.
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 branches or twigs. The growth and therefore, health of the tree is important for ecological purposes.
By lifting the crown, that is to remove the lower branches of the tree, will allow access to the underside of the tree.
This allows for ease of mowing access or space under the tree to allow for shade from the sun if people like to sit enjoying the shade in the summer months when the sun is at its strongest. It also helps to prevent children from climbing the trees which is considered to be a hazard and thus preventing accidents.
