Tree Inventory, and Tree Survey Services

Which One? When? and Why?

Tree Inventory 
Just The Basics.  A listing of each tree, its species, physical characteristics (Trunk diameter, Canopy Diameter, Height, and Clearance), and condition rating (Health, Structural Soundness, and Overall Condition).  

Tree Survey 
A Tree Inventory with locations included, mapped to your site survey - alternatively with geolocation and GIS data for each tree where requested (such as for GIS projects).  

Note: Tree Inventories and Surveys may include pruning, removal, and care recommendations; may also include Tree Appraisal data as requested or where required as part of a development application.

So, who needs which one?

Tree Inventory

Data Included

  • Identification of all trees (and optionally shrubs) - Botanical and Common Name
  • Trunk Diameter (Nominal Diameter for multi-stem trees or caliper for shrubs) - in centimeters.
  • Canopy Diameter
  • Height
  • Clearance (height of lowest branch - trees only)
  • Angle of lean and Canopy offset (if requested/required)
  • Health Rating (Scaled 0-5)
  • Mechanical Soundness Rating (Scaled 0-5)
  • Form Rating (Scaled 0-5)
  • Condition Rating (Harmonic Mean of Health, Soundness, and Form)
  • Observations of Structure (Crowded or poorly formed branches, girdling roots)
  • Observations of Health (Insect, disease, or abiotic pressures)
  • Observations of Soundness (Breakages, Decay or Cavities in branches, trunk, or roots)
  • Pruning, removal or treatment recommendations (optional)
  • Tree Appraisal (optional)

Uses

  • Property purchase (trees in unsound or declining condition can represent a large hidden expense)
  • Setting budgets for tree and landscape maintenance
  • With an added Appraisal, can be useful in establishing a fair offer for certain commercial properties (Tree farms/production nurseries)
  • Just knowing the species and size of trees on the site or in your community
