Tree Preservation Guidelines

Basic Treework Terms:

To help you complete the application form, the following drawings illustrate basic tree work terminology.

Crown Thinning Mainly undertaken to allow more light through the crown without altering the overall size and shape of the tree. The removal of dead and diseased wood (cleaning) followed by crossing and rubbing branches should be carried out prior to thinning to the required density. Proposals should be described in terms of percentage of thinning, e.g. 10%
Crown Lifting This may be carried out to increase the clearance between ground level and the lower branches to: Allow access below the tree To improve light Proposals should be described in terms of height above ground level in metres
Crown Reduction and Shaping This drastic form of pruning, which is allowed in special circumstances only, on certain species of tree, may become necessary for the following reasons: to reduce weight on potentially dangerous branches to balance a mis-shapen tree to prevent trees obstructing or damaging buildings and property Proposals must give the proposed extent of the reduction in metres
Removal of Overhanging Branches In cases where branches overhang gardens, buildings/structures or neighbouring property, the complete removal of all branches that overhang is usually not acceptable. Proposals should state the required clearance in metres

Trees within Neighbouring Properties
In common law a property owner can cut back branches to the boundary of his property. This is permitted as long as:

If work is planned to neighbouring trees you are strongly recommended to inform the owners of the tree. We cannot be held responsible if the work is carried out to trees without the owner's consent.

Reasons for undertaking works
When submitting an application, reasons for the proposed works must be included in the application form. If you are able to support your application with additional information please do so. If you are making an application for removal of a tree because it is causing structural damage to a building the District Council may require a surveyor's report and/or an arboricultural consultant's report.

Replanting
If you propose to replant a tree as part of your application please provide details of the species, position and initial size of the tree you wish to plant.

Tree Surgeons
Many Tree Surgeons will give advice prior to an application being submitted. It is advisable to confirm the contractors liability insurance cover prior to any commencement of work. Obtaining separate quotations is also recommended, especially on larger works, as prices for the same job can vary.
