  T1 Ash Tree: The proposed works form part of routine cyclical tree maintenance. Reduce the crown by approximately 2 metres in all aspects to maintain a balanced crown and appropriate size for its location. Selective crown thinning will improve light penetration and airflow, whilst the removal of major deadwood and crossing or rubbing branches will improve the tree's structural condition, reduce the likelihood of branch failure and promote its long-term health in accordance with BS3998:2010. T2 Cherry Tree: The proposed works form part of routine cyclical tree maintenance. Reduce the overall height by approximately 2 metres and reduce the radial spread to restore a balanced, well-proportioned crown appropriate for its setting. The removal of deadwood will improve safety and the tree's overall condition whilst maintaining its long-term health and amenity value in accordance with BS3998:2010.
