All trees are located in the rear garden of 17 Oakroyd Avenue. T1 - Maple tree to be crown reduce by 2m on the height and 1.5m on the sides. The existing height is 12m and width is 8m The new height will be 10m and width will be 6.5m.

T2 - Beech tree to be crown reduced by 2m on the height and 1m on the width. The existing height is 12m and width is 8m The new height will be 10m and width will be 7m.The proposed selective crown reduction is intended to reduce overall crown spread and end-weight, maintain appropriate clearance from the building and boundaries, improve crown balance, and manage the tree's size in relation to its restricted growing environment. G1 - 7 Conifers that are closely spaced together, which dominate this part of the rear garden and create substantial shading. Their removal is proposed to improve light levels, open up the garden and allow the area to be more effectively managed and landscaped. Importantly, T1 and T2 are to be retained. At present, these trees are situated immediately behind the dense conifer group and are subject to competition for light and growing space. Removal of the 7 Conifers will substantially reduce this competition.
