Trees provide important environmental, aesthetic, and economic benefits, but under certain conditions, they may pose safety risks to people, property, or infrastructure. Professional tree risk assessment helps identify trees that may present a potential hazard and provides guidance for appropriate management.

 

Arbor Insight, LLC, provides professional tree risk assessment services performed by an arborist holding the ISA Tree Risk Assessment Qualification (TRAQ) through the International Society of Arboriculture. This specialized credential focuses on evaluating the likelihood of tree failure and the potential consequences if failure occurs.

 

Our assessments provide objective, well-documented evaluations that support informed decisions regarding tree monitoring, maintenance, mitigation, or removal.

 

What is a Tree Risk Assessment?

Tree risk assessment is a structured process used to evaluate whether a tree or part of a tree may fail and what impact that failure could have on nearby people, structures, or property.

​

During an assessment, the arborist evaluates visible tree defects, structural conditions, site factors, and potential targets that could be affected by a tree failure.

​

The goal of the assessment is to identify potential hazards and provide practical recommendations to reduce risk while maintaining valuable trees whenever possible.

​

Who Needs Tree Risk Assessment?

Professional tree risk assessments are valuable for property owners and organizations responsible for managing trees in areas where failure could affect people or infrastructure.

​

Tree risk assessments are commonly requested by:

• Municipal governments responsible for public trees
• Property managers overseeing commercial sites
• Homeowners and residential property owners
• Homeowners associations (HOAs)
• Schools, universities, and institutional campuses
• Insurance companies and attorneys evaluating tree-related incidents

 

These evaluations help organizations make responsible decisions regarding tree management while documenting due diligence in risk management.

 

Risk Evaluation Methods

Tree risk assessments follow professional practices recognized within the arboricultural industry. Evaluations consider several factors that influence the likelihood and consequences of tree failure.

 

Typical evaluation factors include:

• Visible structural defects such as cracks, cavities, decay, or root damage
• Tree species characteristics and growth patterns
• Soil and site conditions affecting tree stability
• Evidence of previous storm damage or structural weakness
• Proximity to potential targets such as buildings, roads, or gathering areas

 

Assessments follow methodologies associated with the ISA Tree Risk Assessment Qualification (TRAQ) and professional practices outlined in the ANSI A300 Tree Care Standards developed by the American National Standards Institute.

​

Following evaluation, clients receive clear documentation describing the observed conditions, the estimated level of risk, and recommended management options.
