Tree Survey (TS)
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 by the overall scope of the project in consultation with the client(s) and relevant stakeholders. Base data or key attributes for each individual tree will typically include:
The first stage of a Tree Survey requires the precise and meticulous collection of tree data and spatial locations. When the tree data is collected and analysed, it can be utilised:
Frequently Asked Questions
A tree survey (or tree mapping) is a comprehensive survey and assessment of a tree population within a designated site or parcel of land. The first stage of a tree survey is the tree mapping. Tree mapping comprises numbering, tagging, and collecting data for each tree within the site. Once the tree mapping has been carried out and all relevant data has been collected the tree survey report can be prepared.
Tree mapping is used to collect arboricultural data and information relating to the population of trees within a specific site. The type of information that is collected can be tailored to the needs or requirements of the project. Tree mapping is often used by councils or property managers to compile an electronic tree database used for tracking and scheduling inspections, maintenance, or implementing tree management plans.
Tree mapping is an excellent tool for understanding the overall health, condition, quality, or species of trees within the study area. General information collected for each individual tree should include a tree number, botanical name, height, canopy spread, age class, tree significance, useful life expectancy, priority for retention, and trunk diameter at breast height (DBH). The tree survey report should also include a tree location plan prepared using CAD or ArcGIS software. The tree location plan will show the number and location of each tree.
