Environmental assessments and arborists reports
Trees and vegetation can have a major impact on commercial developments, subdivisions, construction projects and land-use changes.
Before work begins, it is important to understand the condition, location and value of existing trees. You may also need to demonstrate how proposed works will affect retained vegetation.
South West Tree Services provides environmental assessments and arborist reports for commercial projects, local government, developers, builders, planners and land managers throughout the Margaret River Region and wider South West of WA.
Our reports provide clear, practical information to support planning, approvals, construction and ongoing tree management.
Arborist reports for development and construction
An arborist report can help identify potential tree-related issues before they affect your project.
Our team can assess existing trees and vegetation as part of pre-development planning, construction and subdivision projects. We consider tree condition, structural stability, environmental values and the potential impact of proposed works.
Depending on the project, an assessment may include:
- Pre-development tree assessments
- Arboricultural impact assessments
- Tree Protection Plans to AS 4970
- Tree Protection Zone (TPZ) calculations
- Construction impact assessments
- Root zone investigations and root mapping
- Tree retention and management recommendations
- Significant tree reporting
Early assessment can help identify which trees can be retained, which may need removal and how important vegetation can be protected during construction.
Environmental assessments for commercial projects
Development projects often need to consider more than just individual trees.
Our environmental assessments can examine vegetation condition, significant trees and habitat or ecological values. This information can help developers and land managers make informed decisions while balancing environmental, safety and regulatory considerations.
We work with builders, developers, planners, councils and property owners to help minimise impacts on retained vegetation during construction and land-use change.
This can be particularly valuable during subdivisions, commercial developments, civil works and larger property projects.

QTRA tree risk assessments
Tree safety can also be an important consideration for commercial properties and public spaces.
South West Tree Services offers Quantified Tree Risk Assessment (QTRA) inspections to assess the likelihood of tree failure and the potential risk to people, property and infrastructure.
QTRA provides an evidence-based approach to tree risk management. Assessments consider factors including site occupancy, target value, tree condition and the probability of failure.
QTRA assessments can assist with:
- Public liability risk management
- Development and construction projects
- School, park and council tree management
- Insurance reporting
- Tree retention decisions
- Storm damage assessments
- Powerline and roadside tree assessments
- Structural defect evaluations
The result is practical and defensible advice to help inform tree management decisions.
Reports for planning, approvals and compliance
An arborist report can form an important part of the planning and approval process for a development or commercial project.
South West Tree Services can tailor reports to suit the requirements of your project, including:
- Planning approvals
- Local government submissions
- Construction and civil works
- Insurance requirements
- Legal and dispute matters
- Property management
- Ongoing tree asset management
Our team combines practical arboricultural experience with recognised assessment methodologies to provide clear reporting that supports informed decision-making.
