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 (DA) or detailed design. The preliminary tree assessment provides base data and information to guide the layout

A geographic information system (GIS) is a conceptualized framework that provides the ability to capture and analyse spatial and geographic data. GIS applications (or GIS apps) are computer-based tools that allow the user to create interactive queries (user-created searches), store and edit spatial and non-spatial data, analyse spatial information output, and visually share the results

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. The extent of data and key attributes collected for each tree is driven

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

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). The tree protection plan is usually included as a component of the arboricultural impact assessment but may also

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. There are various stages in the development process (from site acquisition to completion) where the AQF level

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

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

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
