What is a Tree Survey?
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 of 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.
When should Tree Mapping be carried out?
Tree mapping is used to collect arboricultural data and information relating to the population of trees within the 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.
What sort of information is included within a Tree Survey Report?
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, 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.
How much does a Tree Survey cost?
The cost of mapping trees is variable and usually depends on how much data needs to be collected for each tree. On average, Tree Survey can map and tag up to 120 trees per day at the cost of $1200 (this equates to approximately $10 per tree).
