Tree Risk Assessment

Green Drop Trees offers professional tree risk assessment services to evaluate the likelihood of tree failure and its potential consequences. Our assessments are designed to support informed decision-making for municipalities, developers, property managers, and homeowners—prioritizing public safety, infrastructure protection, and tree health. (for Brief description)

We follow the ISA Tree Risk Assessment Qualification (TRAQ) framework, utilizing a systematic approach to identify and manage risk while preserving valuable trees whenever possible. Our assessments range from rapid visual surveys to advanced diagnostic investigations, tailored to site-specific needs and objectives.

Our services include:

• Level 1 – Limited Visual Assessment: Quick visual inspections of large areas to identify obvious high-risk trees requiring further evaluation.
• Level 2 – Basic Assessment: A 360-degree ground-level inspection using tools such as sounding mallets and probes to assess structural defects, decay, and site conditions.
• Level 3 – Advanced Assessment: In-depth analysis using specialized tools such as resistance drills, laboratory diagnosis and aerial inspections to detect internal decay, root issues, or structural weaknesses not visible externally.

Our risk assessment reports include:

• Tree condition ratings and risk categorization
• Photos and diagrams highlighting key defects
• Recommendations for pruning, mitigation, or removal
• Mapping and prioritization for maintenance planning
• Documentation suitable for insurance, compliance, or liability protection

Whether you are maintaining a city-wide urban forest, managing liability on a commercial property, or assessing trees after a storm, we deliver the clarity and confidence you need to act responsibly and effectively.
