What Trees Are Suitable for Development in Stonnington?
Suitable canopy trees must be capable of long-term growth under urban conditions, supported by adequate deep soil and aligned with Stonnington Council planning requirements.
During planning permit assessment, unsuitable tree selection is a common reason for council RFIs, redesign requests or refusal where proposed species cannot realistically achieve canopy performance on the site.
Assessment is based on:
- Site conditions
- Soil availability and functionality
- Development layout
- Planning overlays and environmental controls
- Long-term canopy performance expectations
Under Clause 52.37 – Urban Tree Canopy, council assesses whether proposed trees can achieve realistic mature canopy outcomes supported by appropriate soil volume and growing conditions.
Our AQF Level 5 arborists recommend canopy species based on long-term site performance and planning compliance, not personal preference or generic species lists.
What Makes a Tree Suitable?
Suitable canopy trees are generally:
- Appropriate to neighbourhood character and local streetscape
- Compatible with available soil conditions and growing space
- Capable of reaching realistic mature canopy size
- Supported by continuous, functional deep soil
- Able to tolerate urban heat, restricted space and environmental stress
- Compatible with planning controls, overlays and site design constraints
A tree is only considered suitable where both the species and the available growing environment allow realistic long-term canopy performance.
Suitability is determined by long-term site performance, not simply appearance at planting stage.
Canopy Performance Under Clause 52.37
Clause 52.37 commonly references:
- 6 metre canopy
- 8 metre canopy
- 12 metre canopy
Assessment is based on whether trees can realistically achieve mature canopy size over time, rather than their size at planting.
Council typically considers:
- Species performance
- Soil functionality
- Available root volume
- Site layout and development constraints
- Long-term structural stability and health
This is a performance-based assessment rather than a fixed approved species checklist.
Example Canopy Trees (General Guidance Only)
Small to Medium Canopy Trees
- Tristaniopsis laurina
- Lophostemon confertus
- Pyrus calleryana (selected cultivars)
Medium to Large Canopy Trees
- Eucalyptus leucoxylon
- Corymbia maculata
- Platanus × acerifolia (where site space allows)
Final species selection should always be site-specific and aligned with planning permit conditions, available soil volume and development constraints.
Deep Soil Requirements – Stonnington
- Continuous rather than fragmented
- Located clear of basement structures where possible
- Wide enough to support root plate development
- Free from excessive service conflicts
- Capable of supporting mature canopy growth and long-term stability
Council assesses deep soil based on functional performance, ensuring trees can realistically achieve their intended canopy outcome under Clause 52.37.
Common Reasons Canopy Trees Are Rejected
- Poor species selection for urban conditions
- Insufficient soil volume or root space
- Fragmented or restricted growing zones
- Conflicts with buildings, basements or services
- Incompatibility with planning overlays or site constraints
- Unrealistic canopy expectations for the available site conditions
Stonnington Vegetation & Canopy Objectives
Council vegetation objectives commonly include:
- Maintaining neighbourhood character and canopy streetscapes
- Protecting established urban vegetation
- Increasing long-term canopy cover
- Integrating canopy outcomes into development design
These objectives align with planning permit assessment and Clause 52.37 canopy performance requirements.
Frequently Asked Questions
No. Trees are generally assessed based on canopy performance, site conditions and planning context rather than a fixed approved species list.
Council considers whether the proposed species can realistically achieve mature canopy growth within the available site conditions.
No. Replacement trees must be suitable for the site and capable of achieving long-term canopy outcomes.
Species that cannot realistically establish or reach mature canopy size under site constraints are commonly rejected.
Species are often rejected where they are unsuitable for the available soil volume, root space, urban conditions or planning constraints.
Council focuses on realistic long-term canopy performance rather than planting intent alone.
Both are critical. Tree species determines canopy potential and growth characteristics, while deep soil determines whether that canopy potential can realistically be achieved on the site.
Council generally assesses species suitability and soil functionality together under Clause 52.37.
