Recommendations

• Prune

• Deadwooding, as described under clause 7.2.2:

• a) Prune to remove dead branches (including stubs)

• Thinning, as described under Clause 7.2.3:

• a) Reduce canopy density through removal of lower order branches whilst retaining the main structural branches of the tree NOTES: • Thinning should not produce the effect of ‘lions tailing’ or ‘feathering’

• Selective Pruning, as described under Clause 7.2.4:

• a) Prune to remove dying diseased and conflicting branches

• b) To allow a maximum 1.5m clearance from the external face and above the roof of the dwelling house, prune to remove branches at the point of attachment or branch collar

• c) Lower branches at point of attachment

• Formative Pruning of Young Trees, as described under Clause 7.2.5:

• Prune branches to: • Enhance form and improve structure, or to directionally shape the young tree • Reduce the development of structural weaknesses • Accommodate site constraints and reduce encroachment on utilities or buildings as the tree grows

• Crown-Lifting, as described under Clause 7.3.3:

• a) Prune to remove the lowest branches to achieve a maximum clearance of X m

• Reduction pruning, as described under Clause 7.3.2:

• a) Prune by reducing the overall length of branches to internal lateral branches NOTES: • The lateral branches to which the final cut is made should be at least one third of the diameter of the branch being reduced at the point of the final cut • Reduction pruning is not lopping or topping

• Remedial Pruning, as described under Clause 7.3.5:

• a) Prune damaged, diseased or lopped branches back to undamaged or healthy tissue

• b) The final cut may not be at the branch collar

• c) Carry out the pruning several stages in an attempt to induce stable and successful regrowth

• d) Manage regrowth by reduction pruning, thinning and/or general pruning

• Regularly monitor the tree to avoid future hazards caused by weak branch attachments
