Dynamic Tree Inspection

Overview

A Dynamic Tree Inspection is an on-site, real-time assessment of trees that evaluates their structural stability and failure potential under environmental conditions, often in response to recent weather events, visible structural concerns, or during routine safety checks. Unlike a static or scheduled tree survey, a dynamic inspection is reactive and situational, typically carried out by a trained arborist when sudden changes in a tree’s condition are observed.

Purpose

Dynamic inspections are used to:

• Assess trees after high winds, storms, or heavy rainfall.
• Investigate sudden changes in a tree’s posture, root plate or canopy structure.
• Examine live hazards, such as hanging limbs, cracks or leaning stems.
• Provide immediate guidance for urgent risk management decisions.

Assessment Process

• Visual inspection from ground level, often using binoculars or pole cameras for canopy observation.
• Evaluation of:
  • Stem and branch structure for cracks, splits, or failure points.
  • Root plate movement, soil heaving, or signs of instability.
  • Fungal fruiting bodies or decay indicators.
  • Crown condition, including dieback, asymmetry or broken limbs.
• May be followed by basic dynamic testing such as gently pushing the tree to observe movement or listening for root plate sounds (done cautiously and by trained professionals only).

Outcomes and Reporting

• Immediate classification of the risk level (e.g., low, moderate, high, imminent failure).
• Verbal or written advice issued on-site or shortly after.
• Recommended actions include fencing off the area, pruning, crown reduction, monitoring or urgent removal.
• Photographic evidence or video may be used to support findings.

Dynamic inspections are especially important in high-use areas such as parks, schools, roadsides and estates, where public safety is paramount and rapid response is necessary.
