  6. Decided - Granted6/2022/1995/EMT

    There are 2 false acacias which have dead and dying branches on them. False Acacia 1 (larger tree) needs all the dead and dying branches removing (I have been advised this will entail reducing the height substantially by about a half). False Acacia 2 (smaller tree, thought to be an off shoot of the larger tree) needs the two large dead branches removing - as this will reduce the tree to only one central branch remaining I would like to request that we can remove the whole tree.
