Tree Stability Assessments

Tree Motion Sensors

In certain situations, it’s crucial to assess whether a tree’s root system is shifting more than expected below ground. This can only be accurately measured using specialised equipment. We use Tree Motion Sensors, which are affixed to the base of the tree, to monitor and quantify the movement of the root plate during windy conditions. These sensors provide precise measurements, allowing us to determine if the tree’s movement is within normal limits or if it indicates potential instability.

PiCUS TreeQinetic Pull Test

We also test stability of trees that are subject to structural root damage during construction and use before and after static pull tests to accurately quantify the structural loss of the tree a determine if it remains stable with the necessary safety factors for the situation. We utilise the PiCUS TreeQinetic pull test manufactured in Germany to complete this highly specialised and useful test.

Utilising Tree Motion Sensors and Static Pull Tests Offers Several Benefits For Our Clients

Enhanced Safety

By accurately measuring the movement of the tree's root plate, we can identify if a tree is shifting more than normal. This helps in assessing potential risks of tree instability, thereby ensuring safety for people and property near the tree.

Informed Decision-Making

The data collected by the Tree Motion Sensors and TreeQinetic provides detailed insights into the tree's condition. This allows us to make well-informed recommendations on whether to undertake additional support measures, adjust maintenance practices, or, in some cases, consider removal if necessary. Measuring tree stability allows more trees to be retained in the urban landscape.

Precise Monitoring

The sensors provide precise, real-time measurements of root plate movement during various conditions, particularly windy weather. This high level of accuracy helps in detecting subtle changes in tree stability that might not be visible through visual inspection alone.

Proactive Management

Early detection of abnormal tree movement enables proactive management. Clients can address potential issues before they escalate, reducing the likelihood of sudden failures or accidents.

Compliance and Documentation

For clients involved in construction or development projects, accurate data from Tree Motion Sensors and TreeQinetic can support compliance with safety regulations and provide documented evidence of the tree's condition, which can be crucial for planning and regulatory approvals.

Cost-Effective Solutions

Identifying issues early through precise measurement helps in implementing targeted interventions, potentially saving costs associated with emergency tree removal or damage repair.

Frequently Asked Questions

Tree Motion Sensors use accelerometers and other technologies to measure and record the movement of the tree’s root plate. The sensors capture data on the extent and frequency of the tree’s movement, especially during high wind conditions, and provide detailed information about its stability.

Tree Motion Sensors are used when there is a need to accurately monitor and measure tree movement, such as:

Assessing tree stability in high-risk areas.

Evaluating trees in storm-prone regions.

Investigating concerns about potential root system issues.

Supporting safety assessments for trees near structures or high-traffic areas.

The benefits of using Tree Motion Sensors include:

Enhanced Safety

Identifying potential instability and reducing risks to people and property.

Accurate Data

Providing precise measurements of tree movement that aid in informed decision-making.

Proactive Management

Allowing for early intervention before problems escalate.

Compliance and Documentation

Supporting regulatory compliance and offering documented evidence for planning and safety purposes.

The data collected by Tree Motion Sensors is analysed to assess the amount of movement and the tree’s stability. This information helps in determining if the tree is moving within normal limits or if it requires further action, such as additional support, maintenance, or removal.

Tree Motion Sensors can be used for a wide range of trees, but their suitability depends on factors like the tree’s size, location, and the specific concerns being addressed. Larger trees or those in high risk areas are typically good candidates for using these sensors, especially when there are concerns about their stability.

The installation duration of Tree Motion Sensors is generally brief, typically taking just a few hours. However, the sensors are usually left in place for a period to collect sufficient data on tree movement under various conditions, often over several days or weeks.

Tree Motion Sensors are installed and monitored by an arborists or tree care professionals who have experience with these specialiSed tools. They ensure correct placement, calibration, and data collection to provide accurate assessments.

While Tree Motion Sensors are effective for detecting abnormal root plate movement and assessing tree stability, they may not identify all types of tree issues, such as internal decay or disease. These sensors are often used in conjunction with other diagnostic tools and visual inspections for a comprehensive evaluation.

The frequency of checking Tree Motion Sensors depends on the specific monitoring requirements and the conditions being studied. Regular data reviews are performed to assess the tree’s stability and to determine if any changes in movement warrant further investigation or action.

Tree Motion Sensors are designed to operate in various weather conditions. However, extreme weather or unusual conditions may affect the accuracy of the readings. Regular maintenance and calibration ensure reliable performance regardless of environmental factors.
