Survey Inspect Assess

Tree surveys are essential for the sustainable planning and management of tree resources. Tree surveys are generally required prior to development planning to allow the identification and sustainable retention of significant trees.

A tree survey is generally undertaken following the preparation of a survey plan provided by a registered surveyor. The survey plan allows us to accurately map and reference existing trees within an AutoCAD document, which can then be modified to graphically illustrate the tree survey data.

Tree surveys may also assess tree populations to provide base line data for succession or maintenance planning. A tree survey will provide an inventory table which captures the following data for each tree:

  • Genus, Species and Common Name
  • Height and Width
  • DBH (Diameter at Breast Height)
  • DRB (Diameter above Root Buttress)
  • Age, Health and Vigour
  • Landscape Amenity, Heritage or Ecological Value
  • Crown Form and Condition
  • Visible Defects or Evidence of Wounding
  • Structural Root Zone Tree Protection Zone
  • Retention Value
