Figure 2. Probing. The tree risk assessor can use
a stiff, small-diameter rod or stick to probe into
cavity openings to estimate their size and extent.

Level 2: Basic Assessment Process
* Locate and identify the tree or trees to be assessed.
* Determine the targets and target zone for the tree or tree parts of concern.
* Review conditions and available site history. Assess general tree health.
* Assess unusual or expected loads, or changes in load, on the tree and its parts.
* Inspect the tree visually-using binoculars, mallet, probe, or trowel, as
desired by the arborist or as specified in the scope of work.
* Record observations of site conditions, defects, and outward signs of
possible internal defects and response growth.
* If considered necessary, recommend an advanced assessment.
* Analyze available data to determine the likelihood and consequences of
failure in order to evaluate the degree of risk.
* Develop mitigation options and estimate residual risk for each option.
* Develop and submit a report, including, when appropriate, advice on
re-inspection intervals.
