Case Study: Validating a Hazardous Tree Survey Diagnosis
At TCI, we specialize in comprehensive tree surveys in Dublin and nationwide, providing the expert arborist’s reports required for planning compliance and risk management. As illustrated in the case study shown in "image.png," proactive assessment is critical to identifying hazards before they result in failure. Whether you are managing mature woodland or a development site, our team provides the rigorous analysis needed to ensure your project meets all safety and regulatory standards.
Tree Assessment Findings
Our assessment of a mature lodgepole pine (Pinus contorta) confirmed the necessity of removal due to a critical combination of pathology and mechanical instability. The tree was infected with Dyer’s maze gill fungus (Phaeolus schweinitzii), an aggressive pathogen that induces rapid, brittle brown rot in the root heartwood, severely compromising the tree's anchorage. Furthermore, the specimen exhibited a pronounced, permanent lean that lacked the physiological capacity to re-stabilize, creating an unacceptable risk of catastrophic failure.
Arboricultural Implications
We streamline the planning process by delivering precise BS 5837 impact assessments, tree protection plans (TPP), and arboricultural method statements (AMS) tailored to your site's specific constraints. By identifying hidden decay pathogens and structural weaknesses early, we help developers and property managers avoid costly delays while ensuring the long-term safety of the site.

Tree Consultancy Ireland Encounters "Eiffel Tower Fungus" in Co. Dublin
TCI recently encountered the "Eiffel Tower fungus" (Inonotus dryadeus) during a routine site inspection. The fungus had colonised the base of a veteran oak (Quercus robur), prompting a distinct buttress formation that closely resembles the base of the Eiffel Tower, hence its unique name.
This selective white rot fungus decays the compressively strong wood of a tree, leaving behind only the cellulose and hemicellulose. It is mainly found on oak species, which frequently show a high tolerance to the fungus due to this reactive buttress development. Indeed, it is a remarkably effective survival response; despite the extent of the colonisation, this specific tree still stands after recent storms.
Conclusion
Identifying specialised fungal growth like Inonotus dryadeus is a critical part of maintaining landscape safety and compliance. Whether you require a comprehensive tree survey report in Dublin or a detailed arborist report to assess veteran trees on your property, our team possesses the specialised knowledge required to evaluate complex structural health.
Furthermore, if you are planning a development, our experts can prepare a formal Arboricultural impact assessment to ensure your project meets all local planning regulations while protecting valuable local canopy.
TCI Tree Risk Assessment & Case Study
Even a seemingly healthy mature common lime (Tilia x europaea) can hide severe defects. Minor dead wood development on one side of the crown prompted a TCI arboricultural consultant to investigate further, revealing extensive decay of the lower trunk and structural roots. The culprit was brittle cinder fungus (Kretzschmaria deusta), an aggressive basal decay fungus that degrades tensile-strong cellulose and compressive-strong lignin fibres, making the wood brittle.
Why 'Healthy-Looking' Trees Can Deceive
Many wood decay pathogens only affect non-living wood, explaining why the crown appeared generally healthy and why these critical issues are often overlooked during a basic visual assessment. In this specific tree, the decay and dysfunction became so extensive that a total disconnect formed between the roots/base and the crown above. A direct correlation was drawn between this hidden base decay and the dead wood appearing in the crown on that exact same side.

Site Assessment: Windthrow and Structural Stability Analysis
An arboricultural assessment was conducted by Tree Consultancy Ireland (TCI) on a private road in Dublin following the recent windthrow failure of a Fir tree (Abies sp.), which caused a total obstruction of the thoroughfare. A detailed inspection of the root plate indicates that the failure was not the result of a single defect but a combination of environmental stressors. While the primary root system exhibited clean, structural snaps—characteristic of a healthy tree subjected to forces exceeding its mechanical capacity—there was also localized root decay on the flank previously affected by the historic failure of a neighboring specimen.
The Impact of Historical Site Alterations
The wider site context, as surveyed by our team at TCI, reveals a concerning trend of instability across the remaining tree population, with dozens of trees showing signs of structural failure. This pattern is a direct consequence of significant historical tree removal, which has fundamentally altered the site's microclimate. Trees that mature within a group dynamic rely heavily on the collective for wind shelter and shared root-plate stabilization. The removal of key specimens has stripped the remaining trees of this essential protection, leaving them vulnerable to increased wind loading and exposing the root systems to mechanical damage and desiccation.
Risk Implications and BS 5837:2012 Standards
In accordance with BS 5837:2012 standards and professional arboricultural best practice, it is evident to Tree Consultancy Ireland that the current state of the group is precarious. The exposure of remaining trees, previously accustomed to a sheltered environment, has created a cascading effect of instability. This site now requires a comprehensive tree survey to mitigate further risk to public and private property, as the failure of one tree in this compromised group significantly increases the likelihood of a chain reaction of structural failures during future weather events.
Professional Recommendations and Remediation
Given the current level of risk, Tree Consultancy Ireland strongly recommends a comprehensive, site-wide tree survey to quantify the structural integrity of the remaining specimens. Our team possesses the specialized expertise required to evaluate group stability, identify high-risk individuals, and develop a phased management plan. By implementing a proactive mitigation strategy, we can address the immediate hazards posed by windthrow and ensure the long-term safety of the site, thereby limiting liability and protecting the surrounding assets. Contact TCI today to schedule a formal assessment and receive a detailed remediation strategy tailored to your site's specific requirements.
Case Study: Arboricultural Assessment of Pinus nigra (Black Pine)
TCI recently conducted a detailed site inspection of a mature black pine (Pinus nigra) to assess its structural integrity and viability within a proposed development site. The specimen suffered a structural failure resulting in the loss of one co-dominant stem, creating a large tear wound extending to the base. Subsequent inspection confirmed the presence of Phaeolus schweinitzii (Dyer's mazegill), which has initiated extensive brown cubical rot through the central stem.
Technical Observations and Risk Assessment
Despite a loss of approximately 60% of the vascular system's circumference, the tree exhibits a surprisingly full crown in good physiological condition. This suggests a high degree of sectorality—a trait often more pronounced in broadleaf species than in conifers, likely influenced by the tree's original co-dominant structure.
In its current location, TCI concluded that the tree could be retained, as it stands in a low-risk zone with sufficient residual sound wood to maintain structural stability. However, as this site is currently subject to a planning application, the tree's retention must be evaluated against the project's Arboricultural Impact Assessment (AIA).
Conclusion and Planning Integration
Should the development footprint require the removal of this specimen, a full Arboricultural Method Statement (AMS) will be required to manage the removal process safely and in compliance with BS 5837:2012 (Trees in relation to design, demolition and construction). TCI continues to provide expert guidance on tree constraints and arboricultural consultancy services to ensure all development works remain in compliance with local authority planning conditions.
