Crown Reduction


Crown reduction is a skilled and lengthy process of reducing the overall size of a tree's crown, while attempting to maintain the natural shape as far as possible.


Crown reduction is often performed on trees under Tree Protection Orders or trees of high value but in poor health, due to fungal infection or disease, as an alternative to felling and removal. The process reduces the risk of failure.

Pollarding techniques are a form of very heavy crown reduction and only performed on deciduous trees such as: Willows, Oaks, Horse Chestnuts, Beeches, Limes, and London Planes etc.


Trees with very heavy crowns and branches such as Willows and Horse Chestnuts tend to be prone to break outs and splits. Pollarding is a method of reducing the weight on those branches considerably, thus reducing the risk of failure. Pollarding causes the tree to generate extensive new growth and once pollarded, it is important to re-pollard or perform a normal crown reduction, every two – three years, to maintain the crown's ideal balance.

Crown thinning


A technique used to remove the inner branches of a tree's crown. This permits higher levels of wind to pass safely through the tree and reduces the sail effect which can cause failure to very large or dangerous trees.


Lack of sun light due to a neighbour's tree is often a cause of dispute. Crown thinning is a preferred method of dealing with this problem by allowing more sun light to pass through the crown.

Crown lifting


Crown lifting raises the trees lower branches to a more acceptable height. This is normally done along public foot paths and fence lines.

As trees grow older or fall prey to ill health, the crown can contain dead braches that can be dislodged or dropped in high winds. A deadwood climbing procedure can remove these branches before they fall, preventing potential damage to the surrounding area or indeed to people in close proximity to the tree.

Tree felling is the complete removal of a tree, most likely due to ill health or urban development. Felling is also used to thin forested areas and harvest timber.

Tree Dismantling


Dismantling is a climbing procedure, where an Arborist takes a tree to pieces and lowers the timber to the ground using ropes and rigging equipment.


Dismantling is required when a tree is too large to fell or is surrounded by obstacles such as houses, sheds, public areas, fences, hedgerows, other trees etc.


Dismantling is a highly skilled and potentially dangerous operation and should only be carried out by a highly competent and experienced Arborist.

Stump Grinding


After a tree has been felled or dismantled, the only thing left is a tree stump cut approx 1inch above the soil level, these can be removed using a stump grinder down to a depth of approx 2 feet.

Note:    Tree Preservation Orders and Conservation Area Applications.


There are many Conservation areas and TPO’s (tree protection orders) in effect within the UK.


Green Tree Works always carries out checks for this legislation and all applications are made directly to local planning authorities before any work is ever undertaken.
