DynaRoot System: Advanced Tree Root Stability and Health Monitoring

At Holly Arboriculture, we utilise the DynaRoot System, a cutting-edge tool designed for assessing tree root stability in real-world wind conditions. This non-invasive technology uses an anemometer to measure wind speed and an inclinometer to measure tree trunk inclination, providing critical data to evaluate tree stability and safety. By using actual wind data, the DynaRoot System offers a more realistic and accurate assessment compared to traditional tree stability tests.

The DynaRoot System is ideal for people that are responsible for managing trees in high-risk environments, such as construction sites, urban developments, or areas with dense tree canopies. However, its benefits extend beyond just high-risk areas – it is also valuable for managing trees in any environment where stability assessments are crucial, such as residential properties, parks, or green spaces. It helps these clients assess tree stability, reduce risk, and make data-backed decisions regarding tree preservation, management, or removal.

Key Benefits:

  • Non-Invasive Root Stability Analysis: The DynaRoot System measures wind pressure and tree inclination to assess the tree’s root stability without causing any harm to the tree or surrounding area.
  • Real-World Wind Data: By analysing how trees respond to natural wind loads, the system provides highly accurate, real-time data on tree stability.
  • Precise Safety Factor Calculation: The system calculates the Safety Factor (SF), which evaluates the risk of a tree uprooting or breaking. A Safety Factor greater than 1.5 indicates low risk, while below 1.0 suggests a high risk.
  • Efficiency for Multiple Trees: Unlike traditional methods, the DynaRoot System can assess multiple trees simultaneously, making it an ideal solution for large-scale tree evaluations in urban areas, construction sites, residential properties, parks, and green spaces. Whether you’re managing a single tree or an entire wooded area, this system provides fast, accurate assessments to support informed decision-making.
  • No Heavy Equipment Needed: the DynaRoot System requires only basic equipment like the anemometer, inclinometer, and data software minimising site disruption
  • Avoid Guesswork: With data-driven insights, appropriate recommendations can be made.

How It Works:

The DynaRoot System uses three key components to assess tree root stability under wind load:

  1. Anemometer: This device measures wind speed (0-150 km/h) at a height of 10 meters above ground. Accurate wind measurements are crucial for simulating the wind load on trees.
  2. Inclinometer: Attached to the root collar of the tree, the inclinometer measures trunk inclination in two directions, providing data on the tree’s movement in response to wind forces.
  3. Evaluation Software: The data from both the anemometer and inclinometer is transferred to the evaluation software, which processes it to calculate the tree’s Safety Factor. The system evaluates the data over a period (recommended 3 hours) to account for the dynamic response of the tree.
