Further Tree Investigations
We specialise in helping you understand your trees and offer a wide range of assessment methods focused on answering that simple but often uncomfortable question……
“Is that tree safe?”
We use a wide range of systems to assess your trees in great detail. We have systems that can look into the soil and below hard surfaces to map where roots are located; we can map and show the extent of decayed wood and assess where decay is likely to be in the future. We even have systems that can assess the stability of the whole tree and understand whether the tree offers a risk of failure through the collapse of the stem or failure of the roots.
We are here to help you understand the implications of defects/attributes and decay to help you better understand the safety of your trees.

Drone Assessments and Mapping
We can offer a wide variety of further investigation and technology-assisted assessments of trees to enable you to better understand your trees and any suspected problems.
To help get a better understanding of the trees in their context, we can offer detailed UAS or Drone Assessments of landscapes, tree populations or individual trees.
Alternatively, if you are concerned about a particular feature such as sudden changes in a tree’s appearance, cracking, fungal fruiting body, mushrooms close to the tree or recent failure, we have systems that enable us to understand the extent and implications of these potential issues in relation to tree and site safety.
Occasionally we need to understand issues at a microscopic level and can help at this level, too. Whether it’s leaf sample testing to understand nutrient or Chlorophyll content, testing soils to understand nutrient content or to test if the soils can suffer shrinkage, identifying root samples or we can even providing DNA of a part of a root to help identify its source.
We can provide internal scans of trees using Sonic and Electronic tomography, using Picus, and Fakopp equipment, in addition to other systems such as Thermal image or Tree RADAR.
If you are concerned about the main stem or even the whole tree’s stability, we can undertake to test using specialist equipment to non-destructively test tree roots and tree stems resistance to predicted loads.
We even have systems that can look into the ground and map the location and depth of the principal roots without disturbing the existing ground cover. Root mapping is possible through soil or even below concrete and tarmac. This can be useful in identifying where trees have caused damage or where proposals to build near a tree may threaten to damage roots directly.
TECHNOLOGY-ASSISTED FURTHER INVESTIGATION
Tree Diagnostics
Occasionally, trees, just like us, can have problems that need an extra level of information to enable better-informed decisions regarding their management or safety.
Some problems cannot be commented on accurately by simply undertaking a visual assessment, a lot like a doctor referring us for further testing before a diagnosis is given.
We offer a range of detailed assessments to help identify, understand and quantify issues, that can affect your trees.
A lot can be gleaned from ground-based visual assessments, and this does form the basis of a lot of our recommendations but when issues are identified, not all is lost and further assessment with specialist equipment might be all that is required to allay any fears or help identify cost-effective or timely management.
These assessments enable us to provide you with an improved level of information and allow us to work with you and provide an informed and balanced management of your trees and landscapes.

We both use and supply specialist equipment and are at the forefront of advanced non-destructive assessments of trees.
Working throughout the UK we provide specialist services to all clients and other professionals, including private individuals, arboricultural Consultancies, Surveyors, Ecologists, Landscape Architects in addition to various Local Authorities and national Landscape Managers.
Our Tree Diagnostics Department www.treediagnostics.co.uk provides training and equipment to other arboricultural consultancies in the UK and Ireland.

DIAGNOSING TREE PROBLEMS
Frequently Asked Questions
What does a tree further investigation involve?
A tree further investigation involves detailed assessments to identify potential issues with a tree’s health, structure, or safety. This may include root inspections, decay detection, or pest and disease analysis.
Why might a tree require further investigation?
Trees may need further investigation if there are visible signs of decay, structural instability, pest infestations, or if they are located near buildings or infrastructure.
Who conducts tree further investigations?
Qualified arborists or tree consultants with expertise in tree health and safety conduct these investigations using specialised tools and techniques.
What tools are used in tree investigations?
Tools such as resistographs, sonic tomography, air spades, and root scanners may be used to assess tree health and structure without causing significant damage.
How long does a tree investigation take?
The time required depends on the complexity of the investigation and the techniques used, but most assessments can be completed within a day.
Will further investigation harm my tree?
Most investigative methods are minimally invasive and designed to preserve the tree’s health while providing accurate information.
What happens after the investigation?
After the investigation, you will receive a detailed report outlining the findings, potential risks, and recommendations for tree care or management.
How much does a tree further investigation cost?
The cost varies depending on the size, location, and condition of the tree, as well as the techniques required. A tailored quote can be provided after an initial consultation.
