Zone Ref Tag No Species Structure Physiology Tree Defects / Issues Recommendations of works (*denotes preferred works) Risk Rating Work Priority
T1 Silver Birch Fair Good Heavy Ivy infestation. Sever Ivy Medium
T2 Horse Chestnut Fair Good Multi-stem (4) tree with compression fork forming on north stems. Cavity at base of south stems but with GRG (S @ 1.2m AGL). Evidence of leaf miner on foliage throughout crown. LHB on adjacent structure roof. CL to clear roof by approximately 2.5m. Monitor stem defects triennially, or following adverse weather events. Medium
T3 Cherry Fair Good Ivy infestation Sever Ivy Low
T4 Field Maple Good Good LHB in close proximity to adjacent structure roof. CL to clear roof by approx. 1.5m. Low
T5 Horse Chestnut Fair Good Multi-stem (4) tree with Ivy infestation. Evidence of leaf miner on foliage throughout crown. Sever Ivy Low
T6 Cherry Fair Good Potential third party owned tree. Heavy Ivy infestation. LHB obscuring school entrance sign. Sever Ivy. CL to clear entrance sign. Medium
G1 Cherry Group of 5 small cherry trees. Minor DW. Potential to obscure access road lighting. Remove DW > 50mm. CR to clear obstruction caused to lighting. Medium
T7 Cherry Good Good Co-dominant tree with compression fork forming at main union. LHB in close proximity to security fence. CL to clear fence by approx. 1m. Low
T8 Field Maple Good Good Self set Cherry at base obscuring school entrance sign. Remove cherry at base. Low
T9 Field Maple Good Good Damaged branch. Remove damaged branch. Low
T10 Cherry Good Good Multi-stem (3) tree with compression forks forming. Monitor triennially. Monitor
T11 Cherry Good Good Lowest limb including security fence (N @ 2m AGL). Monitor triennially. Monitor
T12 Sycamore Fair Fair Significant damage to bark on main stem. Signs of potential squirrel damage to branches in upper crown. DW Remove DW > 50mm. Monitor bark defects triennially, or following adverse weather events. Medium
T13 Cherry Good Good Minor DW Remove DW > 50mm Low
T14 Poplar Poor Good Potential third party owned tree. Large split limb overhanging school field. Signs of decay/damage at base of overhanging limb (W @ 6m AGL). Remove full limb, that includes split limb back to stem. Remove overhanging limb with damage at base. (See annotated picture) 6 High
T15 Apple Fair Good Hollow stem but with GRG. Monitor triennially. Monitor
T16 Norway Maple Fair Good Damage to main stem (S @ 0.8m to 1.8m AGL) Monitor triennially. Monitor
T17 Horse Chestnut Decaying Fair Multi-stem (3) tree with historical limb failure. Significant decay at base, decay probe able to penetrate below root plate (600mm+). Damage with associated decay throughout main limbs. Although the tree is demonstrating good reactional growth its structural integrity is compromised and unsuitable for retention. Fell (Marked with orange paint dot) 9 High
T18 Norway Maple Poor Fair Catastrophic limb failures in upper crown with multiple hanging branches. Large split at IBU (S @ 2.5m AGL). Evidence of internal decay in main stem with FFB, possibly Auricularia mesenterica, in cavity (W @ 2m AGL) and emerging through IBU. Fell (Marked with orange paint dot) 10 Urgent
G2 Incl. Beech, Field Maple, Whitebeam, Sycamore, Horse Chestnut Woodland group consisting of mature mixed broadleaf trees. Vegetation and construction waste stacked at the base of multiple trees. Trees in decline. DW Remove vegetation and construction waste from base of trees. Fell trees in decline (Marked with orange paint dot). Remove DW > 50mm, prioritising areas to the edge of the woodland group where in close proximity to school field. Consider recommendations for converting woodland group into 'Nature Area'. Medium
T19 Norway Maple Fair Good Potential third party owned tree. Compression fork with prominent elephant ears. Monitor triennially, or following adverse weather events. Monitor
T20 Norway Maple Fair Good Potential third party owned tree. Compression fork with prominent elephant ears, with damage to fork on east. potential to fail onto adjacent pubic highway. Crown reduce by approx. 6m. 8 High
G3 Incl. Norway Maple, Sycamore, Hazel, Elder, Apple Woodland group consisting of mature broadleaf and shrubs. Overgrown understory restricting access to majority of group. Dead trees. Failed tree resting on security fence. DW. Ivy infestation. Evidence of public access through damaged security fence (School Informed). Unsecure gas substation (School Informed). Fell Dead trees (Some have been marked with orange paint dots where accessible). Remove failed tree resting on security fence. Remove DW > 50mm prioritising areas in close proximity to adjacent residential properties. Sever Ivy on large trees. Retain 'wild' state for wildlife habitats. Medium
G4 Incl. Tree of Heaven, Field Maple, Finnish Whitebeam, Cherry Construction waste (soil) piled at base of multiple trees. Damage caused by mechanical plant to bark on multiple trees. Finnish Whitebeams on north edge of group in decline. DW Remove construction waste from base of trees. Remove DW > 50mm from all trees in group. Monitor trees in group for decline annually. Medium
T21 Norway Maple Good Good Recent construction work has excavated, and installed new pathway within the trees root protection area (RPA). Construction work breeched 5m RPA by 2.5m. Monitor for decline annually. Monitor
G5 Incl. Willow, Norway Maple, Ash, Mixed Shrubs Overgrown group obstructing windows, and in close proximity to structure roof and guttering. Small dead ash tree (ADB) Remove small trees, including dead ash then reduce and maintain remaining group to 0.5m below windows. Low
