Tree species: Silver Wattle Number used on sketch plan: T2 Description of works: Removal T2 Silver Wattle is located very close to a building, and has the potential to outgrow its citation very quickly. While this has been managed with cyclical pruning in the past, Silver Wattle are a vigorous species and prone to decay. Removal and replacement is recommended to avoid an intensive cyclical pruning regime, and reduce the future risk of damage to the nearby drains. Tree species: Cider Gum Number used on sketch plan: T7 Description of works: Removal T7 appears to have been windblown historically, ie the tree’s root system has partially failed. While it is reasonably stable now, the acute angle of stem lean and the vigorous nature of the species mean that cyclical pruning will be required to manage the canopy.
