Decay In Trees
Internal Dysfunction
Decay Inspection
During routine tree inspections and surveys, Arborists often identify trees affected by decay fungi.
Decay can develop in various parts of a tree, such as the roots, trunk, and crown, potentially affecting its stability and health. Arborists typically detect it through visual signs, such as fungal fruiting bodies, cavities, and scars left by fallen fungal brackets. In addition, they may look for other indicators of decay, which can help pinpoint areas of concern.
In addition to visual assessment, professionals use specialised techniques to detect internal decay. One common method involves sounding the tree trunk with a nylon or rubber mallet, which helps identify hollow or weakened areas by detecting changes in sound. As a result, it provides valuable insight into the tree’s condition.
If internal decay is suspected, further investigation might be necessary, depending on several factors, including:
• The tree’s amenity value and its contribution to the surrounding environment.
• Its historical significance and cultural value, which contribute to its importance within the community and heritage..
Its health as well as specimen quality.
• Whether the tree is protected or not, which can influence the steps taken for its management.
• The potential risk it poses in case of structural failure.
Regular tree health assessments are essential for maintaining safety, longevity, and environmental value. If you suspect decay in a tree, don’t hesitate to reach out to us, and we will help you determine the best course of action, ensuring that the tree's health and safety are effectively addressed.
Cavity Investigation
Resistograph Drilling: Precision Decay Detection
The Resistograph® is an advanced tool that Arborists use to detect internal tree dysfunction and hollowing while causing minimal impact.
How It Works:
A fine needle drill penetrates the tree, measuring wood resistance, which creates a graph that reveals hidden dysfunction, cavities, or weakened fibers, providing valuable insight into the tree’s internal condition.
Why Use Resistograph Testing?
• Identify internal decay before visible symptoms appear.
• Assess structural stability in order to ensure safety and preservation.
When Is It Needed?
Resistograph drilling is ideal for trees showing decay signs, those in high-risk locations, or trees of historical and ecological value, since it provides a precise analysis with minimal disruption.
Professional Arborists use Resistograph testing to ensure safety, longevity, and informed decision-making, which allows for precise tree health assessments.
Internal Investigation
Data Analysis & Risk Mitigation
We carefully analyse the data collected from Resistograph drilling to assess the extent of internal decay and structural stability, which helps in making informed decisions about the tree's condition.. Subsequently, based on the findings, expert recommendations are provided to mitigate risks and ensure tree safety, thereby helping to prevent potential hazards.
Possible actions may include:
• Targeted pruning. Arborists perform targeted pruning to reduce strain on weakened areas, which helps improve the tree’s overall health and stability, therefore enhancing its resilience.
• Crown reduction. Arborists carry out crown reduction to reduce stress on the stem, thereby helping to improve the tree's structural integrity and overall health.
Bracing or cabling. Arborists use bracing or cabling to support structural integrity, which ensures the tree remains stable and resistant to external forces, thus enhancing its durability.
• Ongoing monitoring is essential for tracking changes in decay progression, allowing for timely interventions and ensuring the tree’s continued health and safety.
• Tree removal may be necessary if the risk of failure is too high, ensuring safety and preventing potential damage or injury.
This analysis enables Arborists to make informed decisions, carefully balancing tree preservation and public safety.
