  FRONT: ONE Catalpa / Indian Bean tree (approx HEIGHT 8m ) (T1) - REMOVAL of TWO dangerous Branches. REASON: The first has snapped and is hanging in the canopy. The second is a hazard beam that has horizontal splits. Both should be removed to mitigate health & safety issues as the gardens are a high volume area. Informative A: to thank for retaining the tree for amenity, wildlife and shade to reduce increasingly high summer temperatures due to climate change. Informative B: please create habitat log piles with arisings for wildlife and biodiversity.

  FRONT (London Rd): ONE Bay (T1)(ht.7m) FELL. Reason: it is located approximately 1m from the main foundations of the building so removal will mitigate future issues. A mediterranean garden will be planted up as a replacement as an example of a drought resistant form of urban planting. REAR (by nursery): ONE Beech (T2)(ht.8m) FELL. Reason: it is dominated by the larger beech & yew trees growing nearby leading to phototropic lateral growth towards the nursery that will cause problems for the gutters & roof. Another beech tree will be planted a little further away in the south downs. REAR (by nursery): ONE Yew (T3)(ht.10m) CROWN REDUCE HEIGHT by 1m from 10m to ht.9m, LATERAL REDUCE by 2m from 8m to 6m Southern laterals. Reason: to rebalance the tree keeping a natural aesthetic. Informative A: the replacement tree for beech (T2) is hugely appreciated to maintain the treed character of the gardens, for amenity, wildlife and shade to reduce increasingly high summer temperatures due to climate change. Informative B: please create habitat log piles with arisings for wildlife and biodiversity.

  REAR (nature trail): ONE Lime (T1)(approx ht.12m) LATERAL REDUCE SPREAD by 2m from 11m to 9m on E compass point, no height reduction. Reason: to give 2m clearance from the lamp column, pruning to suitable points to maintain natural aesthetic. REAR (nature trail): ONE Sycamore (T237)(approx.ht.12m) LATERAL REDUCE by removing dead stem. Reason: the stem has died, remove for health & safety reasons, the tree will remain. REAR (nature trail): ONE Sycamore (T264)(approx.ht.14m) LATERAL REDUCE by removing south stem which has died. Reason: the stem has died, remove for health & safety reasons, the tree will remain. REAR (nature trail): ONE Prunus (T3)(approx.ht.8m) FELL. Reason: strong eastward lean over the footpath that runs through the nature trail, poor physiological condition noted previously, lean appears to be worsening, replant with another prunus - see informative A below for alternative species. REAR (nature trail): Sycamore (T2) remove deadwood and stub ? exempt works. Informative A: the proposed replacement for Prunus T3 is greatly appreciated to maintain the woodland habitat for wildlife and visitors wellbeing, suggested alternative species to Prunus: alder buckthorn, grey or goat willow, hazel, purging buckthorn, elder. Informative B: to thank for retaining the treed character of the disused rail line for amenity, wildlife habitat and shade to reduce increasingly high summer temperatures due to climate change. Informative C: please continue creating habitat log piles with arisings for wildlife and biodiversity.

  REAR (near mini golf): ONE London Plane (T174)(ht:approx.20m) FELL and replace. Reason: basal fungal brackets, declining physiological condition (loss of fine twigs, large areas of bark loss on upper branches seen from disabled parking area), resistograph results show very low resistance in the low stem holding wood hugely increasing the likelihood of failure; given the size of the tree, the proximity to the mini golf course, on higher ground than adjacent disabled parking area, the combination of the compromised strength and high footfall mean the tree must be removed to prevent health & safety issues in the future; a native species tree is proposed to be planted as a replacement. Informative A: the proposed replacement tree planting is hugely appreciated to maintain the treed setting and amenity of the Horniman Gardens. In view of the specimen trees and arboretum character of the gardens, a large canopy replacement tree is suggested with species such as: hornbeam, oak, wild service tree, London plane, cut leaved beech, Indian horse chestnut, wingnut, Japanese pagoda tree, golden rain tree. Informative B: where possible please continue to retain safe standing dead timber or create habitat wood piles on site and lay cut branches between stakes as a linear 'dead hedge' for wildlife and biodiversity.

  FRONT: ONE Lime tree (T1) Ht 15m FELL to ground level & treat stump REASON: A remedy to the differential foundation movement at the insured property and to ensure the long-term stability of the building. To limit the extent and need for expensive and disruptive engineering repair works at the insured property. To limit the extent and need for costly CO2e emissions relating to alternative engineering repair works at the insured property. It is the case that an alternative to felling such as pruning or significant 'pollarding' of the tree would not provide a reliable or sustainable remedy to the subsidence in this case. We do not consider that any other potential means of mitigation, including root barriers, would be effective or appropriate in the circumstances. We are satisfied that the evidence obtained following completion of our Arboricultural Implication Assessment report completed 31/01/2024 clearly links the Lime T1 and False Acacia T2 as the cause of damage to the risk address. REPLANTING: Insurers understanding the requirement to offer replacement planting in the event consent to fell is granted. 43 DEVONSHIRE ROAD TREE PRESERVATION ORDER 2024 DC/24/135159

  9 EXETER PLACE, LONDON, SE26 6AB

  REAR (fronting Wells Park Rd) ONE Sycamore (T2, in TPO A1)(ht.12-14m) FELL by dismantling to safe standing stem or high stump. Reason: health & safety, the tree is in severe physiological and structural decline, leaning towards the road, several branches have already failed, and although a small amount of live growth remains, the tree has no meaningful long-term viability, the significantly compromised structure presents an unacceptable risk of further branch or whole-tree failure onto highway. The proposed removal is necessary to eliminate the risk. The replacement tree is to be a large canopy species planted as near as practicable to the original location. The County of London (Lewisham No.2) Tree Preservation Order, 1957. Informative A: thank you for proposing 4x replacement trees, 1x is required to be a large canopy tree to replace the TPO tree and to maintain the treed boundary character to Wells Park Road for public streetscape amenity, wildlife and shade to reduce increasingly high summer temperatures due to climate change ? Hornbeam, Hop hornbeam, sessile oak, Japanese Pagoda Tree, walnut (Juglans regia), Italian alder or grey alder, Caucasian Elm (Zelkova carpinifolia), small leaved lime, Hackberry (Celtis australis), Turkish hazel (Corylus colurna), Kentucky Coffee Tree (Gymnocladus dioica) - see further planting details below. Informative B: thank you for planting additional voluntary trees for screening, to improve species diversity, and the setting of the property. Informative C: thank you also for looking to retain a safe standing stem/high stump and creating habitat log piles with some dead wood arisings for wildlife and biodiversity.

  12 PRINCETHORPE ROAD, LONDON, SE26 4PF

  REAR: ONE Lombardy Poplar (T1)(ht.16m) CROWN REDUCE by 10-11m to ht.5-6m, REDUCE SPREAD from 10m to 5m to create new pollard. Reason: multi-stemmed tree has had a major stem failure exposing large cavity approx.2m above gd level. Remaining stem above cavity is weighted towards neighbouring properties and a crown reduction to reduce weight and sail above cavity is urgently needed to minimise risk of future failures. Merely reducing the one stem would drastically change the balance of the overall canopy and exposure to wind would be likely to cause more failures on the remaining stems. Crown reduction is required for safety to reduce overall canopy to approximately 5-6m from ground level (please see annotated photo) to create a new pollard. Informative A: thank you for managing the tree by safe reduction to retain as a low pollard for rear amenity, wildlife and canopy shade to reduce heatwave temperatures due to climate change. Informative B: please create habitat log piles with arisings for wildlife and biodiversity.
