    T1 - Tree of Heaven – Multi-stemmed, approximately 12m in height with a 6m lateral spread. Proposed Works: Fell to ground level. Reasoning: 1. Safety concerns This tree poses a genuine safety issue. There’s significant decay within the main limbs and an included union around 2.5 m. One of the larger limbs extends directly over a busy public footpath, and there’s a high risk of failure. Removing that limb would leave a large wound, leave the tree unbalanced, and severely reduce its already poor amenity value - effectively making it unsustainable to retain in its current form. 2. Invasive species Tree of Heaven is a recognised invasive non-native species in the UK (listed under Schedule 9 of the Wildlife and Countryside Act 1981). It spreads quickly through root suckers and seed, outcompeting native species and reducing biodiversity. Giving this species TPO protection goes against current ecological guidance and local biodiversity objectives. 3. Limited amenity value This particular specimen is small, decayed, and poorly formed. It offers very limited visual or environmental benefit. Based on its condition, I struggle to see how it achieved a TEMPO score high enough to justify a TPO, and I’d appreciate a copy of the completed assessment form for review.

    Tree of Heaven – Multi-stemmed, approximately 12m in height with a 6m lateral spread. Proposed works: Fell to ground level. Reasoning: The tree exhibits a significant included union at approximately 2.5m, with further decay evident around 3m, including woodpecker holes/damage. The brittle nature of Tree of Heaven increases the likelihood of limb or total failure. Given the tree’s close proximity to a public footpath there are genuine safety concerns.
