  Tree Works Justification Conservation Area Notification The proposed works relate to three trees located within a designated Conservation Area and are intended to provide reasonable management of tree size, form, and proximity to built structures, whilst ensuring the long-term health, safety, and amenity value of the trees is retained. T001 Acer The Acer has developed a moderately extended canopy which is beginning to outgrow the available space within the garden setting. The proposed minor crown reduction of approximately 1.0 m in height and 1.0 m in radial spread is intended to bring the canopy back into proportion with the surrounding garden and nearby structures. The reduction will be carried out by pruning back to suitable growth points, retaining the trees primary framework and a high proportion of foliage-bearing structure. This approach represents good arboricultural management, maintaining the trees natural form whilst preventing future overextension. T002 Apple Tree The Apple tree currently has two primary limbs extending over the garage roof, creating potential for debris accumulation and ongoing contact with the structure. Removal of these limbs back to the main stem will provide appropriate clearance from the building. The remaining canopy will be pollarded at approximately 2.5 m above ground level, establishing a compact and manageable framework for future growth and facilitating long-term maintenance. In addition, the ivy present on the stem will be severed at the base to prevent further encroachment into the canopy, allowing improved inspection and reducing additional loading on the tree. T003 Olive Tree The Olive tree has developed a dense and extended canopy which would benefit from light management pruning. A modest crown reduction of approximately 1.5 m in height and 1.0 m in radial spread is proposed to improve overall structure and maintain the tree at a scale appropriate to the garden environment. The works will retain the main frame

  T1 - Blue Atlas Cedar. - Lateral branches, predominantly in the lower crown, but also partially mid to upper crown: Shorten selected branches that extend significantly beyond the main foliated body of the crown, removing up to 3 metres of growth from the longer branches, but more commonly 1.5-2 metres from others. - The top growth will not be pruned; so the aim is to reduce the width to achieve a more compact/uniform appearance, but without pruning where it is not necessary. T2 - Copper Beech - Lowest South east facing lateral branch over the the neighbours garden: Shorten back by 2 metres.
