  T1: Robinia - Removal - The mature Robina tree has dieback in the crown, and extensive deadwood throughout. Bark is flaking away at base of the tree, showing the outer wood to be decaying. Propose to sectional fell, cutting the trunk as close to ground level as possible. T2: Apple - Removal - Ivy has over taken the majority of the crown. Remove ivy and fell to ground level. T3: Eucalyptus - Pruning - The mature eucalyptus has previously been pollarded, resulting in vigorous regrowth. Ivy has also surrounded the trunk and has established itself over the entire tree. Propose to sever and remove all the ivy, reduce the regrowth back to previous pruning point, leaving suitable furnishing growth where possible.
