Tree renewals

The City of Stonnington exceeds the 90% industry health target for an urban tree population as 94% of trees managed by Council are currently categorised as being in good health.

Tree health changes over time and is dependent on many factors, including environmental conditions, soil conditions, pests and diseases, maintenance history and history of root disturbance.

A large proportion of the trees managed by Council are mature or over-mature. Trees at the end of their useful lives offer limited benefit, present a greater risk of failure and also prevent the planting of replacement trees.

Maintaining and increasing the current high canopy cover into the future will involve:

› Planting and establishing young trees

› Maintaining semi-mature trees

› Retaining and protecting healthy mature trees

› Removing trees that have reached the end of their useful lives.

Unhealthy trees

The City of Stonnington continues to monitor and identify unhealthy trees and manage them appropriately. This may mean proactive maintenance works such as mulching, treating for pests or diseases, deep watering or adding additional nutrients although in some circumstances, removal may be the only option.

Street Reconstructions

Road reconstructions provide an opportunity to redesign the road layout or create new growing spaces for street trees. If existing trees are unhealthy, these projects allow for the replacement of the existing trees with new trees and improved growing conditions.

Providing high quality public infrastructure, while also maintaining and expanding the urban forest, is important to ensure the ongoing liveability of the city. Large trees provide the greatest benefit to the community, however they also have a large root system which can impact surrounding areas.

If any issues arise between a tree and existing private or public infrastructure, Council will explore all possible tree management, design and engineering solutions before tree removal is considered.
