TRAQ Level 2 · ANSI A300 Part 9

ISA TRAQ risk analysis

ISA Tree Risk Assessment Qualification Level 2 documentation aligned with ANSI A300 Part 9 — site, targets, loads, defects, and the likelihood × consequence matrix. Upload annotated photos (close-ups of each defect, wide shots of the target zone) for an arborist-reviewed risk rating and mitigation plan.

Step 1

Assignment & site

Per ISA TRAQ BMP (3rd ed.) — context before observation.

Purpose of the assessment*

Risk assessment time frame*

Site use*

Site disturbances affecting the tree (select all)

Wind / load history (last 12 months)

Step 2

Tree identification & condition

Tree ID / tag (optional)

Species — common name*

Known failure profile for this species

DBH — diameter at breast height (4.5 ft)*

Estimated height*

Life stage*

Vigor*

Prior failure history of this tree

Step 3

Targets within fall zone

TRAQ defines the target zone as the area within 1.5× tree height where the tree or part could fall.

Targets in fall zone (select all)*

Highest-value target (one sentence)*

Distance from trunk to highest-value target*

Occupancy rate of highest-value target (ISA BMP Table 3)*

Is target relocation or restriction feasible?*

Step 4

Load factors & exposure

Wind exposure*

Crown density / sail area*

Edge-tree status

Lean — angle from vertical*

Lean — character*

Step 5

Defects observed

Use the photo upload step for annotated close-ups of each significant defect.

Roots / root collar (select all)

Trunk / stem (select all)

Branch unions / architecture (select all)

Branches / canopy (select all)

Primary defect of concern (one sentence)*

Part most likely to fail*

Most likely direction of failure*

Step 6

Risk rating — ISA TRAQ matrix

ISA BMP: Likelihood of Failure × Likelihood of Impact → Combined Likelihood; Combined Likelihood × Consequences → Risk Rating.

1. Likelihood of failure (within stated time frame)*

2. Likelihood of impacting target (if failure occurs)*

3. Consequences of impact*

4. Risk rating (from ISA BMP matrix)*

Brief rationale for the rating*

Step 7

Mitigation & re-inspection

Recommended mitigation (select all that apply)*

Residual risk after mitigation*

Recommended re-inspection interval*

Additional observations / context

Photos

Upload up to 6 photos.

Clear daylight images help our arborists evaluate before a site visit. Wide shots of the whole tree plus close-ups of the affected area are most useful. JPG/PNG/HEIC, 8 MB each.
