Gale Tree Consultancy

Offering a range of consultancy services from a simple, visual assessment of your tree stock to a more in-depth assessment using the most modern, hi-tech decay evaluation equipment.


At Gale Tree Consultancy we believe in giving our clients the very best advice possible in relation to the management of their trees and with over 20 years’ experience in the field of arboriculture, this is what we do.


We offer a range of consultancy services from a simple, visual assessment of your tree stock to a more in-depth assessment using the most modern, hi-tech decay evaluation equipment. Mortgage Reports can be drawn up to aid those in the process of buying a property along with a climbed inspection to assess those branches or areas of concern not visible from the ground. We can also work with architects and developers in the production of a BS5837 Arboricultural Impact Assessment and Arboricultural Method Statement to help integrate trees into the built environment and buildings in to the treed environment.



Visual Tree Assessment

A visual tree assessment is simply that, from ground level, we look at your tree or trees and assess them for any defects or hazards that may compromise their life expectancy, we then produce a written report detailing the findings and any remedial work necessary. Large numbers of trees can be assessed and plotted using our Magellan Mobile Mapper CX which has a sub-metre accuracy.

Aerial Visual Tree Assessment

The tree or trees are climbed and an aerial assessment performed on those parts of the tree either not visible from the ground, or that require a more in-depth inspection; an example of this could be cavities from a failed limb or for the assessment of Massaria disease Splanchnonema platini (formerly known as Massaria disease) on London plane trees.

Resi PD400 Microdrill

Using a 400mm long fine drill bit, the Resi F400 measures the resistance of the drill bit against the timber; the more resistance the drill encounters, the more sound the timber and conversely, the lesser the resistance, the less sound the timber.


The resultant drill trace is described as a graph detailing when and where, in terms of depth, that the drill encountered any defects.


The Resi F400 can be used at ground level or at height and is a great accompaniment to the Picus sonic tomography unit.

Picus Sonic Tomography

By inducing sound waves across the stem of a tree and measuring how fast the sound waves reach corresponding sensors, an internal picture of any decay or hollowing present can be achieved. The tomogram produced not only creates an image of the decay or hollowing but also the extent; the findings are then presented in a written report along with any remedial action that may be necessary.

BS5837 Arboricultural Impact Assessment and Arboricultural Method Statement

At Gale Tree Consultancy, we can offer advice from the outset regarding trees in relation to a new development with an initial site visit and discussion following on to the survey of the trees on site and those located off site that may impact on the proposed development. We can produce the Arboricultural Impact Assessment required to evaluate the direct and indirect effects of the proposed design of the development to the trees on site and where applicable, recommend mitigation options.


From there, the Tree Protection Plan and Arboricultural Method Statement can be produced to aid the developer in their implementation of the protection of the trees. Our involvement need not stop there as we can also act as the liaison between you and the local planning authority and help with any other queries that may arise during the course of the build.

Home Buyers
Arboricultural Report

Buying a home can be stressful especially when the mortgage lender asks if there are any trees close to the property. At Gale Tree Consultancy we can act swiftly to assess the proposed new property and any trees that may be present. This is also a good opportunity to meet with the potential new buyers to discuss future management requirements of the trees on site; we will always be honest and offer the best possible advice.
