Tree Inventory Services

Each tree is recorded by species, diameter at breast height (DBH), estimated height, crown spread, overall condition rating, structural defects noted, maintenance needs, and GPS location. We can also include a tree tag number. Each tree gets a maintenance priority (routine, soon, urgent) and an estimated timeline for required work. The final deliverable is a signed PDF report, a spreadsheet and a site map, with a GIS data export on request.

Tree inventories are most commonly requested by property managers and condo boards who need to plan and budget annual tree maintenance, developers conducting due diligence before acquiring or developing a site, municipalities managing parks or public trees, commercial property owners preparing for large-scale maintenance or capital planning, and HOAs with shared green space responsibilities.

Cost is driven by the number of trees being surveyed and the total site area. Site accessibility and terrain affect how long the field survey takes. Data format requirements add time when your property management system needs a custom export or GIS-compatible file. Inventories supporting a development permit application require additional documentation and cross-referencing with municipal bylaw thresholds. We provide a firm quote before any work begins. The report arrives within 2 business days of the field survey.

A tree inventory is a survey and documentation exercise. It records what trees exist on a property and their general condition. A tree risk assessment focuses specifically on quantifying the probability and consequence of tree failure for individual trees that present a potential hazard. An inventory often flags trees that need a formal risk assessment. When a property has hazard concerns, we can do both.

The standard deliverable is a written report with a summary table listing each tree. We can also provide the data as a spreadsheet (Excel or CSV) for import into your maintenance management system, a site plan with tree locations plotted, or a GIS-compatible data file if you have mapping software in place. If you need a specific format for your system, let us know before the survey and we will accommodate it.

Update it every 3 to 5 years, and again after any storm, major construction or large-scale tree work. Properties with many mature trees or active construction need it more often. We can also add individual tree assessments to an existing inventory on an as-needed basis between full surveys.
