Tree Surveying and Inventories
Systematic, data-driven tree surveys for Melbourne properties, councils, developers, and strata managers.
Professional Tree Surveying Services in Melbourne
A tree survey is far more than a count of what's growing on a site. It is a systematic, methodical process that catalogues and assesses every tree on a property or precinct, building a permanent record of species, condition, risk, and management needs. For Melbourne property managers, developers, councils, and strata bodies, a well-executed tree survey is the foundation for everything that follows - from maintenance budgets to development applications.
Melbourne Arborist provides professional tree surveying and inventory services across metropolitan Melbourne. Our arborists use current Australian industry standards, field-tested data collection protocols, and modern mapping technology to deliver surveys you can actually use. Whether you manage a small residential strata block or a large municipal tree population, we build tree inventories that give you clear, actionable information.
Every tree survey we complete is tailored to the specific needs of the client. The scope, data fields, reporting format, and deliverables are agreed upfront so the finished product integrates directly with your existing asset management or planning processes.
What Is a Tree Survey?
A tree survey is the systematic cataloguing and assessment of all trees on a defined property or site. Each tree is individually identified, measured, assessed for condition and risk, and recorded in a structured database or report.
Individual Tree Records
Each tree is assigned a unique identifier. Its species, size, location, and condition are recorded independently, creating a permanent, traceable record for every individual on the site.
Condition Assessment
Beyond identification, each tree is assessed for structural condition, health rating, pest and disease signs, and estimated useful life expectancy using recognised arboricultural criteria.
Spatial Mapping
Tree locations are recorded using GPS coordinates or mapped onto site plans, allowing the survey data to integrate directly with GIS systems, CAD drawings, or asset management platforms.
Risk Classification
Each tree is risk-rated based on likelihood of failure and consequence to people, property, or infrastructure. Risk ratings drive prioritisation for maintenance and removal planning.
Management Recommendations
The survey output includes specific recommended actions for each tree - pruning, treatment, monitoring, or removal - with priority classifications to guide budgeting and scheduling.
Digital Database Delivery
Survey data is delivered as a structured digital database - spreadsheet, PDF report, or GIS-compatible format - ready for import into your existing asset management system.
What Gets Recorded in a Tree Survey
The data fields captured in a tree survey depend on the purpose and scope of the inventory. For most Melbourne surveys, we record the following for every individual tree:
Species
Botanical and common name, confirming whether the species is native, exotic, or listed as significant under local planning overlays.
DBH (Diameter at Breast Height)
Trunk diameter measured at 1.4m above ground - the primary metric for tree size and a key determinant of permit requirements under many Melbourne councils.
Height and Canopy Spread
Estimated or measured tree height and the radius of canopy spread in four cardinal directions, defining the tree's above-ground footprint.
Health Rating
Condition score from excellent to poor based on canopy density, leaf condition, bark integrity, and signs of pest or disease activity.
Structural Condition
Assessment of structural integrity including co-dominant stems, included bark, previous failures, lean angle, and any visible decay or cavities.
Useful Life Expectancy
Estimated remaining serviceable life in years, used to prioritise long-term planning and budget allocation for maintenance or replacement programs.
GPS Coordinates
Precise location data allowing trees to be mapped, filtered, and displayed spatially - essential for large sites and GIS integration.
Types of Tree Surveys We Conduct
Pre-Development Survey
Completed before any development application is lodged. Documents existing trees, identifies those within the development footprint, and establishes retention candidates requiring tree protection plans during works.
Council and Municipal Survey
Large-scale inventories for local councils covering street trees, park trees, and reserve trees. Provides the data backbone for maintenance scheduling, budget planning, and community canopy reporting.
Strata and Body Corporate Survey
Inventories for apartment complexes, commercial buildings, and managed estates. Defines which trees are common property, their current condition, and recommended maintenance to inform sinking fund budgets.
Insurance and Asset Survey
Formal tree inventories for insurance risk management, public liability purposes, or asset valuation. Provides documented condition records demonstrating due diligence and proactive management.
Bushfire Assessment Survey
Identifies trees within bushfire attack level zones and assesses their relevance to ember attack risk, radiant heat, and fire spread potential. Used to support BAL assessments and planning applications.
Heritage Tree Survey
Specialist surveys identifying trees of botanical, historical, or cultural significance. Documents current condition, threats, and recommended conservation actions for heritage registers and planning submissions.
When a Tree Survey Is Required
- Development Applications - Most Melbourne councils require a tree survey and impact assessment when development is proposed near significant trees. The survey defines which trees are retained and what protection measures apply.
- Council Requirements - Local councils increasingly mandate periodic tree surveys for high-risk locations such as school grounds, public spaces, and aged care facilities to satisfy duty of care obligations.
- Strata Management - Body corporates and owners corporations use tree surveys to allocate maintenance responsibilities, inform sinking fund estimates, and document the condition of common property trees.
- Insurance and Risk Management - Insurers and risk managers require documented evidence that tree assets are regularly inspected and managed. A current survey provides that evidence and supports claims or defences if incidents occur.
- Property Purchase Due Diligence - Buyers of commercial or large residential properties commission pre-purchase tree surveys to understand the condition and management obligations of the tree asset before settlement.
- Asset Management Programs - Organisations managing large property portfolios use tree inventories to plan maintenance cycles, allocate budgets, and track the performance of their tree asset over time.
The Tree Survey Process
Scope Definition
We establish the survey boundary, required data fields, reporting format, and deliverables with the client before any field work begins.
Field Survey
Arborists systematically work through the site, assessing and recording each tree using mobile data collection tools and GPS devices.
Data Collection
All measurement, condition, and location data is captured digitally in the field, minimising transcription errors and enabling direct export.
Analysis
Collected data is reviewed, cross-referenced against council overlays and planning controls, and assessed for patterns in risk or condition across the site.
Reporting
A formal survey report is prepared covering methodology, key findings, priority management recommendations, and supporting photographs.
Database Delivery
The complete tree inventory is delivered in your preferred format - spreadsheet, PDF report, or GIS-compatible file - ready for immediate use.
Tree Inventory Databases and Digital Records
A tree survey is only as useful as the database it produces. We structure our deliverables so the data you receive is ready to work with from day one, whether you need a spreadsheet, a GIS layer, or a management platform import file.

Benefits of a Professional Tree Survey
- Informed Decision-Making Reliable data on every tree on the site removes guesswork from management decisions. You know what you have, what condition it is in, and what it needs.
- Budget Planning A complete tree inventory with management recommendations lets you accurately forecast arboricultural expenditure over 1, 3, and 5-year horizons instead of reacting to unexpected costs.
- Risk Management Risk-rated tree data lets you prioritise attention and resources on the trees most likely to cause injury or damage, reducing your exposure and demonstrating proactive duty of care.
- Regulatory Compliance A current tree survey gives you the documentation needed to satisfy council permit requirements, demonstrate compliance with vegetation overlays, and support development applications.
- Environmental Planning Canopy data, species distribution, and ecological values identified in the survey inform environmental impact assessments, sustainability reporting, and urban greening programs.
Technology Used in Our Tree Surveys
GIS Mapping
We use GIS software to spatially locate, display, and analyse tree data. Survey results can be delivered as shapefiles, KML layers, or georeferenced PDFs for direct use in mapping and planning systems.
Drone Surveys
For large sites or areas with limited ground access, drone surveying provides aerial canopy overview, high-resolution imagery for condition assessment, and accurate canopy spread measurements.
Mobile Data Collection
Field arborists record all survey data digitally on mobile devices in real time, eliminating paper-based data entry errors and enabling faster data processing and report delivery.
Digital Tree Tags
Physical tree tags with unique identification numbers can be installed during the survey, creating a permanent on-tree reference that links to the digital inventory record for ongoing management.

Frequently Asked Questions
In practice, the terms are often used interchangeably. A tree survey refers to the process of going out and collecting data on trees, while a tree inventory is the structured database or record that results from that process. When we complete a tree survey for a client, the deliverable is the tree inventory - a usable dataset built from the field survey work.
Field time depends on site size and tree numbers. A small residential strata site with 20-30 trees can usually be surveyed in a single day. A medium commercial site with 100-200 trees typically takes 2-3 days on the ground. Large municipal surveys may require a week or more of fieldwork. Report preparation and database delivery generally adds 5-10 business days after fieldwork is complete.
Yes, and this is one of the most common uses. Many Melbourne councils require a tree survey as part of a development application when significant trees are present. The survey identifies all trees on and adjacent to the site, assesses their condition and retention value, and informs the tree protection plan. We can tailor the survey methodology and report format to meet specific council requirements in your local government area.
For tree surveys used in development applications or planning submissions, the arborist should hold at minimum AQF Level 5 qualifications (Diploma of Arboriculture or equivalent). For surveys submitted to councils or courts, certification and professional indemnity insurance are standard requirements. All our survey arborists hold relevant industry qualifications and the appropriate insurance coverage.
We can deliver tree inventory data in whatever format best suits your use case. Standard options include a structured Excel spreadsheet, a formal PDF report with tree schedule appendix, GIS shapefiles or KML layers for mapping platforms, and custom import files for asset management systems such as TechnologyOne, IIMAK, or similar CMMS platforms. We agree on the deliverable format before fieldwork begins.
Yes. For ongoing tree management programs, councils, and strata managers, we offer scheduled repeat surveys that update the existing tree inventory rather than starting from scratch. The resurvey compares current condition against the previous record, flags trees that have declined or been removed, and adds any newly significant trees. This gives you a longitudinal record of how your tree population is changing over time.
TPZ (Tree Protection Zone) and SRZ (Structural Root Zone) are calculated buffer distances around a tree that define how close construction or excavation can safely occur. For development application surveys, calculating TPZ and SRZ for retained trees is generally mandatory. We include these calculations as a standard component of pre-development tree surveys and any survey prepared for a planning submission.
We can assess neighbouring trees from within the boundaries of your property or from the road reserve. To physically access and measure trees on a neighbouring property, permission from the landowner is required. For development application surveys, it is common to note and estimate data for neighbouring trees without direct access, with that limitation clearly stated in the report methodology.
