It is proposed to remove three Beech trees (T1, T2 & T3 on sketch plan) from within the rear garden. Beech T1 has a large Ganoderma bracket on the eastern side of its stem. There is also a small bracket emerging from the south-eastern side of its stem (see photos). When advanced, Ganoderma can result in a tree's mechanical failure of its stem, base or root plate. Beech T1 therefore has a limited safe useful life expectancy. The proposed work will ensure the tree does not fail unexpectedly in the future. Beech T1 and Beech T2 have grown together as a pair. The removal of one tree (T1) will leave the other tree (T2) more exposed during strong winds. The remaining tree will also look unsightly and unbalanced (if left). Beech T3 is dead (exempt) To mitigate, one new standard-sized Beech tree will be planted as close as possible to T2.
