  Tree believed protected under TPO 481 – Group G1. Tree reference on attached site plan: T06 – Beech (highlighted red). Location: Road frontage, approx. 5 metres from the dwelling and directly adjacent to a well-used public footpath. Proposed Works: Complete removal (sectional dismantling) to ground level of T06 Beech. All works to be undertaken by a qualified and insured arborist in accordance with BS3998:2010 – Tree Work Recommendations. Reasons for Proposed Works: Following inspection by two independent licensed arborists, Paul Avery (PA Tree Care) and Jody (Clear Cut Gardens Tree Care & Landscape), full removal is recommended based on the following: Structural Condition & Decay: The tree is over-mature. There is a significant trunk wound with exposed sapwood from ground level to approx. 2m on the western side (approx. 35cm wide at base). Basal hollowing is present behind and above the wound. Daldinia concentrica fruiting bodies are visible at approx. 1.8m, indicating decay and compromised structural integrity. There is evidence of internal decay within the lower stem. Crown Condition: Extensive deadwood is present in the upper crown. Multiple branches retain leaves consistent with branch death. Deadwood has begun to detach and fall. Structural Weakness: A tight fork union increases the risk of structural failure under load. Public Safety Risk: The tree is directly adjacent to a heavily used public footpath near LVS School and approx. 5 metres from the dwelling. Deadwood has already fallen onto the house frontage and the public footpath. Given the decay, fungal activity, basal hollowing and falling deadwood, there is a foreseeable and increasing risk of branch or partial stem failure, with potential for pedestrian injury and property damage. Due to its roadside position and high foot traffic, risk exposure is significant. Consideration of Alternatives: We initially sought advice for minor deadwood works. However, both arborists concluded that crown reduction would not address basal decay, dead-wooding alone would not mitigate structural risk, and retention would present ongoing liability concerns. Removal is therefore considered the only reasonable risk mitigation option. Replacement Planting: We are willing to comply with a replacement planting condition, provided it does not adversely affect the remaining trees. Supporting Information Submitted: In accordance with guidance below, we have included a sketch plan showing boundaries, road, footpath, adjacent properties and T06 marked in red; photographs showing the trunk wound, basal hollow, black fungus, crown deadwood and tight fork union; and referenced observations from two licensed arborists. Urgency: While catastrophic failure has not occurred, the decay, falling deadwood and proximity to a school route and public footpath present a foreseeable risk. We respectfully request timely consideration to mitigate potential injury.
