A homeowner near Beauly recently contacted us regarding a large mature Ash tree that had become increasingly unsafe due to extensive internal decay and structural deterioration. Although the tree was still alive externally, significant defects within the stem meant failure was becoming far more likely, particularly during periods of strong Highland winds.
Following a detailed inspection and risk assessment, we carried out a controlled tree removal to safely dismantle the compromised tree before it became an emergency situation.
This project highlights the importance of early tree inspections, particularly with mature Ash trees showing signs of decay, hollow cavities, or structural weakness.
If you are concerned about a dangerous or declining tree on your property, you can contact our team for professional arborist advice.

When we arrived on site, the scale of the internal decay quickly became apparent. The Ash tree had developed a substantial hollow cavity through the centre of the trunk, with large sections of compromised timber visible throughout the stem.
From the outside, the tree still retained some live growth, which can often give the impression that a tree remains structurally sound. However, internal decay can severely weaken the load-bearing strength of a tree long before complete decline becomes obvious.
In this case, the decay had progressed to the point where the tree presented a clear long-term safety risk.
The client was understandably concerned about:
Following our inspection, we advised that removal was the safest and most responsible solution.
Mature Ash trees can become hazardous when affected by extensive decay, disease, fungal activity, or internal cavities. Trees in this condition may remain standing for years before suddenly failing, particularly during poor weather conditions common across the Scottish Highlands.
A hollow or partially decayed stem significantly reduces structural stability and can increase the likelihood of:
Many dangerous trees still appear healthy from a distance, which is why professional arborist inspections are so important.
At The Highland Arborist, we carry out detailed assessments to determine:

Before any cutting work began, we completed a full site assessment and removal plan to ensure the safest approach for the property and surrounding area.
This included:
As with all of our tree work, wildlife inspections were completed before removal commenced to ensure there were no nesting birds or protected species present within the tree cavity.
The extent of the internal decay meant the dismantling process required careful handling throughout. Severely weakened timber can behave unpredictably under load and tension, making experience and planning essential when removing dangerous trees safely.

Due to the advanced decay present within the stem, the tree was dismantled in controlled sections to minimise risk and maintain complete control throughout the removal.
The work carried out included:
Where possible, usable timber from the Ash tree was processed and stacked into manageable firewood blocks for the client to reuse.
All remaining branches, smaller material, and green waste were chipped and responsibly removed from site using professional wood chipping equipment.

At The Highland Arborist, we always aim to reduce unnecessary waste wherever practical. Salvaging suitable timber for firewood is one way we help homeowners make use of material that would otherwise require disposal.
This approach:
Responsible waste handling is an important part of modern arboriculture, particularly for larger removals on rural Highland properties.

The dangerous Ash tree was safely dismantled and removed before structural failure occurred, significantly reducing long-term risk for the client and surrounding area.
Once the work was completed:
The internal condition of the tree clearly demonstrated how serious the decay had become. By addressing the issue early, the removal could be carried out in a controlled and planned manner rather than becoming an emergency response following collapse or storm damage.
