Supporting healthy, resilient tree populations

A deeper understanding of your trees' insides.

By combining visual assessment with advanced diagnostic tools, it becomes possible to identify internal decay, structural weakness, physiological stress, and site-related limitations that influence overall tree performance.

This approach allows for a more precise and targeted understanding of tree condition. Rather than relying on external symptoms alone, diagnostic methods help reveal underlying causes of decline, supporting clearer decision-making around retention, management, or treatment options. It also helps prioritise interventions where they will have the greatest long-term benefit.

Together, these services support a proactive approach to tree care, focusing on early detection, informed intervention, and improved long-term health outcomes. By understanding both internal structure and external growing conditions, arborists can develop more effective strategies to maintain safety, vitality, and resilience within the urban forest.

Our Services

Sonic Tomography & Resistance Drilling

Sonic tomography and resistance drilling are non-invasive tools used to assess a tree’s internal structure and condition.

Sonic tomography uses sound waves to map changes in wood density inside the trunk, helping identify areas that may indicate decay or weakness. It creates a visual representation of internal structure that cannot be seen externally.

Resistance drilling measures the resistance of wood as a fine drill passes through the trunk, providing precise data on internal condition at specific points. This helps locate and confirm areas of compromised wood.

Together, these methods give a clearer picture of internal tree health, supporting informed decisions about risk, retention, and treatment while minimising unnecessary removal.

Aerial and Drone Assessments

Aerial and drone assessments use remote imaging technology to safely inspect tree canopies and upper structures that are difficult to access from the ground.

Drones capture high-resolution imagery and video from multiple angles, allowing detailed inspection of crown structure, branch unions, canopy density, and signs of dieback or damage. This provides a clear view of areas that are often hidden or difficult to assess using traditional ground-based methods.

This approach improves both safety and efficiency by reducing the need for climbing or heavy access equipment, particularly on large or complex sites. It also allows for consistent documentation of canopy condition, supporting more accurate assessments and comparisons over time.

The data collected can be used to inform risk evaluations, maintenance planning, and ongoing monitoring of tree health. By capturing repeatable visual records, aerial assessments help track change over time and support more confident, evidence-based decisions.

Soil & Tissue Analysis with PHC Programs

Soil and tissue analysis, together with Plant Health Care (PHC) programs, focus on understanding and improving the growing conditions that support long-term tree health.

Soil analysis examines key factors such as structure, nutrient availability, pH, moisture, and biological activity. This helps identify limitations in the root environment that may be affecting tree performance, including compaction, nutrient imbalance, or poor drainage. Leaf and tissue analysis provides complementary insight into how effectively a tree is absorbing and utilising available nutrients.

PHC programs use this information to guide targeted treatments that improve overall site and tree health. These may include soil improvement, mulching, fertilisation, pest and disease management, and watering strategies designed to address underlying causes rather than just visible symptoms.

Together, these approaches support stronger, more resilient trees by focusing on the conditions that sustain growth. By treating the root environment as a living system, arborists can improve vitality, reduce stress, and enhance long-term canopy performance.

Tree Injection Treatments

Tree injection treatments deliver targeted solutions directly into the vascular system of a tree, allowing for precise treatment of pests, diseases, or nutrient deficiencies.

Using specialised injection systems, active compounds are introduced into the trunk where they are transported through the tree’s vascular pathways. This method ensures controlled distribution to the areas where it is needed most, improving effectiveness while minimising environmental exposure.

Because treatments are applied internally, tree injection can be a more efficient alternative to traditional spraying methods, particularly in sensitive or high-traffic environments. It is commonly used to manage conditions such as systemic pests, fungal pathogens, or specific nutrient deficiencies.

When used as part of a broader plant health care strategy, injection treatments support targeted intervention and improved recovery outcomes. This helps maintain tree vitality, reduce decline, and extend the useful life of valuable trees.
