A tree risk assessment is typically performed by a qualified arborist. The arborist will assess a variety of factors that include soil conditions, what structures are endangered if the tree falls, the overall health of the tree, wind exposure, etc.

Tree risk assessments rely on identifying and assessing structural condition to assess failure potential. 'Defect' is the term we commonly use to identify a condition or characteristic that is structurally weak or contributes to a structural weakness.

THE TREE RISK ASSESSMENT Qualification (TRAQ) was designed to provide a systematic process for assessing tree risk. Part of the process was to devise a simple field data collection form. The form now used in teaching the course went through many iterations before it was released.

Basic is the standard assessment that is performed by arborists in response to a client's request for tree risk assessment. Inspection tools: binoculars, hypsometer, magnifying glass, mallet, trowel, shovel, & probe may be used. Drilling for root and trunk decay may be included for an additional fee.

During a Level 2 Basic assessment, Arborists walk completely around a tree and look for defects in all visible areas of a tree, including the surrounding area. These assessments include the use of a rubber mallet for "sounding" the tree and probes that can be used to evaluate open cavities.

It is a systematic process for assessing trees for defects, predicting the likelihood of failure and prescribing risk mitigation. It is a methodical process of inspecting trees, identifying defects such as structural faults, fungal decay or physiological decline.

The Tree Risk Assessment Form is more than a rating record of potential tree hazards for a particular site. It is a record of the overall structural condition of a tree that can be used to determine progression of defects over time and to document the frequency of certain defects.

The Forest Service inspects campgrounds and other developed sites for tree hazards in order to provide a safe environment for forest visitors. Insects and diseases that infest trees are a natural part of the ecosystem, providing food and habitat for wildlife.

A tree health assessment is done to determine a tree's health condition. A professional arborist can also perform a risk assessment but only at the owner's request.

The 3 Levels of Risk Assessment This level involves looking at the tree's roots, trunk and crown to detect structural defects. It is a 360 degree, ground-based visual observation of the tree. Level 3: Advanced Tree Risk Assessment. This level is anything in excess of level 2.
