Why it was refused
- The oak tree is located in the rear garden of 21 Arden Mhor and has an attractive, natural canopy. It is visible from neighbouring properties as well as from Arden Mhor itself, providing a clear contribution to the local landscape. The tree offers moderate to high amenity value and plays a significant role in maintaining the established arboreal character of the area. Given its condition and species characteristics, it also has the potential for a long lifespan. This application has been refused as no valid arboricultural justification for the proposed works was provided. The requested 6Ã?¢?¯m crown lift combined with a 20% crown thinning is considered excessive and likely to adversely affect the tree's amenity value. The work to the cypress on this application may be undertaken as the trees are not covered under TPO 85A Please note that the removal of deadwood may be carried out under the statutory exemption without formal consent. Having regard to the reasons given for the proposed work, the work is unjustified and will have a detrimental impact on the visual amenity and arboreal character of the area.
- The removal of deadwood, dangerous / hanging branches and ivy: This does not require the formal consent of the Council.
- Wildlife and Countryside Act 1981: Note that it is an offence under this act to disturb roosting bats, nesting birds or any other protected species. Therefore, if applicable, it is advisable to consult your tree surgeon / consultant to agree an acceptable time for carrying out the approved works.
- Owner(s)'s permission: Permission should be sought from the owner(s) of the tree(s) and / or the owner(s) of the land that the tree(s) overhang prior to any approved work being carried out.
- Expected standard of tree work: The approved works must be carried out in accordance with the conditions laid out above. If they are not, then enforcement action could being taken which could lead to prosecution and heavy fines. Therefore, it is highly recommended that the works are only carried out by a professional and competent arboriculturist who undertakes to comply with the conditions of this consent and in accordance with industry best practice (BS 3998:2010). The Arboricultural Association can provide details of its approved contractors, who have demonstrated such professionalism and Council can provide a list of contractors who are known to carry out tree work to a good standard and to normally maintain an appropriate policy of indemnity insurance.
