Who We Are

Tree Survey is a respected Australian owned business comprising a small team of highly skilled consulting arborists.

Our reliability and dedication to all our projects have been the foundation for our growth and success. We have a deep understanding of the planning approval pathways and the requirements that need to be met for each process. Our core competencies are in preparing detailed arborist reports to support the following processes:

Complex infrastructure and development projects require the detailed arboricultural assessment of trees against a background of multiple disciplines including, architecture, engineering, and landscaping. Our expertise in geographic information systems (GIS) and drafting, allows us to absorb and analyse each layer of the development in detail. All of our work is georeferenced and can be integrated into existing project models (CAD, GIS).

Organisations we work with

Tree Survey's Services

Tree Survey specialise in the detailed assessments and management of large tree populations. Our key areas of expertise are as follows:

Arboricultural Impact Assessment (AIA)

An arboricultural impact assessment (AIA) is a detailed and comprehensive report that reflects the potential impacts of development on trees within and adjacent to a proposed development site.

Tree Protection Plan (TPP)

A tree protection plan (TPP) generally follows the arboricultural impact assessment (AIA). The tree protection plan provides details on tree protection mitigations for trees that are proposed to be retained (as determined by the arboricultural impact assessment).

Tree Risk Assessment (TRA)

A tree risk assessment (TRA) is a detailed analysis of the risk posed by a single tree or group of trees within a specific site. Tree risk assessments are often carried out at schools, universities, holiday resorts, parks, and other public spaces where trees have the potential to cause harm to the persons who occupy that space.

Preliminary Tree Assessments (PTA)

A preliminary tree assessment (PTA) is a comprehensive survey or assessment of trees within a designated site or parcel of land. These reports are often used in the earliest stages of development planning, prior to the development application or detailed design.

Tree Surveys

A tree survey (TS) is a comprehensive assessment of a specified tree population. A tree survey is typically undertaken with the aim of providing base data on the existing tree population to assist in the management and future planning around those trees.

Project Arborist Services

The project arborist is responsible for carrying out the inspections, supervision, monitoring, and certification of trees during a development project. Details of the project arborist are often required to be submitted to the consent authority prior to construction.

GIS and Spatial Analysis

A geographic information system (GIS) is a conceptualised framework that provides the ability to capture & analyse both spatial & geographic data.

Tree Database

A tree database or register is a means to store, retrieve, display, sort, and summarise data (information) that relate to tree assets. This can be an important and useful tool to assist and the planning, management, and maintenance of large tree populations. Our expertise in geographic information systems (GIS) allows us to create, manage and maintain large data sets with extreme precision and attention to detail.

Tree Management Plan (TMP)

A tree management plan (TMP) is a comprehensive survey or assessment of trees within a designated site or parcel of land. These reports are often used to guide the future use, management, and maintenance of a site. The tree management plan provides base data and information, including the existing health and condition of the trees and any risks that the trees may pose.

Expert Witness Services

Expert witnesses provide a range of services related to their specialized knowledge and expertise.

Frequently Asked Questions

A preliminary tree assessment (PTA) is a comprehensive survey or assessment of trees within a designated site or parcel of land. These reports are often used in the earliest stages of development planning, before the development application (DA) or detailed design. The PTA provides base data and information to guide the layout of the development, including opportunities to retain existing trees. General information for each tree will include the following:

  • Identification: Allocated number and botanical name.
  • Dimensions: Tree height, canopy spread measured to four cardinal points, and trunk
    diameter.
  • Condition: Tree health, structure, and age class.
  • Significance: Tree significance, useful life expectancy, and priority for retention.
  • Protection zones: Tree protection zone (TPZ) and structural root zone (SRZ).

An arboricultural impact assessment (AIA) is a detailed and comprehensive report that reflects the potential impacts of development on trees within and adjacent to a proposed development site. The assessment provides detailed information on the impact of building, infrastructure, stormwater drainage, and landscape construction on the trees within and adjacent to the proposed footprint. The
arboricultural impact assessment will identify any trees that may need to be removed and trees that can be successfully retained. General information for each tree will include:

  • Identification: Allocated number and botanical name.
  • Dimensions: Tree height, canopy spread, and trunk diameter at breast height (DBH)
  • Condition: Tree health, structure, and age class.
  • Significance: Tree significance, useful life expectancy, and priority for retention.
  • Protection zones: Tree protection zone (TPZ) and structural root zone (SRZ).
  • Impacts: Any conflict between the development footprint and the tree protection zone.

A tree protection plan (link to page) generally follows the arboricultural impact assessment (AIA). The tree protection plan provides details on tree protection mitigations for trees that are proposed to be retained (as determined by the arboricultural impact assessment). The tree protection plan is usually included as a component of the arboricultural impact assessment but may also be supplied as a standalone document.

Our tree protection plans include detailed drawings that are prepared using AutoCAD or ArcGIS drafting software. The general information that is typically included in a tree protection plan includes, but is not limited to:

  • The location of each tree, and its identifying number.
  • Color-coded diagrams showing which trees are proposed to be retained and removed.
  • The extent of the Tree Protection Zone (TPZ) and Structural Root Zone (SRZ).
  • The location and type of tree protection that is required. This may include tree protection
    fencing, trunk and branch protection, or ground protection.
  • Site-specific tree protection mitigations, including locations for non-destructive excavation
    (NDE) or where the arborist may need to supervise works.

Most consent authorities will not accept an arborist report unless the author has an AQF level 5 qualification in Arboriculture (Diploma of Arboriculture). All of our consulting arborists have a minimum AQF level 5 in Arboriculture, many of our consulting arborists also have an AQF level 8 (Graduate Certificate of Arboriculture) and the internationally recognised Tree Risk Assessment Qualification (TRAQ) and Quantified Tree Risk Assessment (QTRA).

Our standard turnaround time is two (2) weeks. We offer priority and emergency services for an increased fee.
