TG1 Coniferous Tree Group (3 trees)Goal:Sectional dismantle: Group of 3 trees - using rigging equipmentReasons: The group of three conifers is located in very close proximity to the residential property, with the canopy directly overhanging the roofline and guttering, thereby creating an ongoing risk of physical damage from branch contact and movement during adverse weather conditions. The dense evergreen foliage is contributing to excessive shading of the building and surrounding area, likely promoting damp conditions and restricting natural light. The close proximity and direct canopy contact with the building may also facilitate access for climbing animals such as squirrels, increasing the potential for pest ingress at roof level. The trees are growing in close formation, resulting in suppressed and uneven growth characteristics, which can compromise structural integrity and increase the likelihood of failure. Furthermore, their position adjacent to the building raises concerns regarding potential root-related impacts on foundations and underground services.T2 Ash StemGoal: Pollard back to previous pruned pointReasons: Part of cyclical maintenance to ensure the ongoing health and safety of the tree.
